I'm glad you did not cut out the deburring of the chuck jaws. This is important information for some of the younger viewers. Also, shows your attention to detail. I am constantly watching your videos, keep up the excellent work!! Also, make longer videos and don't worry about the length, people can fast forward through the parts they may find boring. I like watching all the processes of the job.
I happened to run into this video and found it absolutely fascinating. I'm not a machinist. The amount of care and expertise required to produce such a part is really remarkable. And you explain it so patiently.
Really enjoying your videos, I am an engineer from the UK but not involved with CNC machining. Your calm approach really shows a depth and sophistication which reflects true craftsmanship. Many thanks for taking the trouble to do these videos.
You truly have a amazing machine . I'm a old Tool Maker now I've used three and four axis cnc wire edm and sinkers . But the work that can be done on the type that you have just swings the door wide open . Great job keep them coming . Thanks Old Tool Maker Fort Worth Texas
Man I wish I got to run tiny parts like this on my 650H. Mine has a 26” SMW air chuck and never have parts under 20” diameter or so. Nice video tho. I like how you went through the whole process with the material prep and Jaw stetup. Most people don’t get to see all the stuff needed before even turning the part.
You are a top notch machinist, my friend. I enjoy all of your videos. I am glad you didn't cut the jaw prep out of the video because there are a lot of people out there that don't realize how much goes into making a part and the added cost.
That was one of my biggest fears, "crashing the machine". Back in the day, I watch a co-worker crash one of our Kitamura's 80xi's (from the late 80's to 90's edition's), mind you, that was all I needed to see, to put the fear of god in me, to never take for granted, the amount of power these machines have at their disposal to convert into absolute violence and chaos. Those were 10 and 15 hp machines, LOL... You have my respect, as per, the 60 hp, units that you play with everyday. One missed step, and it is costly. Nice job, again on the video. The engraver pencil (although, you assumed there wouldn't be any interest in that footage), was that real time motion, and what was the type of cutter or abrasive used,... fluted, stone, diamond?.. meaning, it plowed right on through the material... Drew
I worked for GE in the gas turbine division thay had some rather large VTLs with a 20' dia. chuck 3 rams i dont even remember what the HP was but anyway i seen a cowerker setting one up and the left hand ram was down and just alittle close to the jaws when he started the machine up it winded up and hit the jaw with a bang i can still here today and continued on to the next 3 jaws Bang Bang Bang knocking all 4 jaws clean off the chuck and into the air flying till the machine came to a stop because those machines dont just come to a stop when you hit the stop button nedless to say i gained alot of respect as to the power of those machines its a good thing it was the night shift and there werent that many people there because toes jaws landed right in an spot that people would have bin if it were day time to this day i check and dobble check and tripple check as to the clearance on any chuck that i am running
At some point everyone will crash a machine. Sadly it happens. The worst one I saw was on a bullard with a 48" chuck. Guy just wasnt paying attention and restarted the program with the tool inside the part. It blew the entire 600lb assembly out of the machine through the doors and into the floor where he WAS standing. Called that guy Usain Bolt for years. Another guy went full rapid into the spindle of a SL35 and blew the Jaws off the face. I crashed a 3" boring bar on a Mori nh6300 into an alignment pin I forgot to take out of a part for line reaming. Never feels good.
User Name I’ve been indicating parts in when we turn od’s in two op’s we blend em and send them. Forgot to handle my turret up and away when I finished indicating and went to cycle start. We ran some long big boring bars in the turret at the time and it just indexed around immediately till it met my part in the chuck. Was more scared I had to go tell boss man. Haven’t made the same mistake yet though that’s true with all my crashes lmao
Excellent video, very well detailed. I have worked with Mazak lathes of 2 and 3 (QT-28 and QT-35) axes but that video machine is another level. Thank you
No iam glad you didn't cut the jaw prep out of the vido because there are alot of people out there that dont relize how much goes into making a part thay think just put it in the machine and make the part so thats a good thing
@@Fabiable Better holding power with a 4 jaw. Spin that size shaft that fast sticking out that far while facing and there's a good chance of chucking the part in a 3 jaw.
Fabian Nenning 4 jaw chucks are much more precise when well adjusted. 3 jaw chuck will always shake a little bit (around .003") so if your tolerance is thighter than that you got to use the 4 jaw chuck
@@RochCroque what a bullshit, if you use soft jaws on a 3 jaw chuck and have a workpiece with a good face and turned surface, you will get 0.00mm concentricity. And i had faced/turned the ram shaft first with hard jaws into his diameter, on the this "T" side. Then clamped on soft jaws and turned the thread and etc. Switched to clamp on the diameter and milled the other side... Time is money and you as americans should understand it the most...
These videos show how incredibly meticulous your work is. If only there were shops like this here in my area, I'd apply there especially since I get my Journeyman's Card next month. (4th year tool and die maker)
Peter, great job, thanks for the video. That surface pattern seems to be from either a cold drawn bar, or a cold worked and forged bar, before its heat treatment. This part must get some serious cyclic compression loads for them to have given you such a stock.
Hey peter. You don't remember me but me and my father worked for your company in Texas. I use to clean your machines when I was a kid. My father remembered you. Miss your work
thank you for sharing your videos , you allmost show all the process , i will keep on watching, this is really related to my job. i love making set-up work .
I always enjoy your deburring and emphasize on a clean workspace. It might seem like a waste of time, but dealing with a bad cut for the next few days is a bigger waste of time. Avoiding the possible injury, you are far better off . Repeated bandages and time dealing with it. Plus the pain of the injury and the slowly healing wound. One of those things you learn when you get older.
So nice to see videos about the specifics of CNC setup from a genuine working professional. So much of the stuff on YT is either amateur or pure theory from applications techs. Also, Okuma has a envelope travel limit feature (I'm 90% sure Mazak does as well, but its been most of a decade since I ran one). It basically puts a soft limit on the travel in both directions in whichever axis you need. I use it a lot to basically guarantee that I won't hit my jaws or center. On jobs like this especially, it helps to reduce the pucker factor.
Duncan Thanks for your comment. The Mazak also has what they call safety barriers (I usually turn them off). That doesn't help when your in the cam software. In Esprit TNG you are working with a accurately defined model of your machine. So it will tell you in anything is wrong down to .001" or better or what ever you define. This is particularity helpful on a mill turn doing milling on the face of a part. Many of them have limited travel in the X minus direction. (Min has only 10 mm X minus travel) So if the simulation shows you going out of machine travel in the X minus direction You can change the C axis solution or machining strategy to correct the problem. Without that you would have to find out when you run the machine. This can be as little as .0001" so without this ability in the software you can't see it in a normal simulation. If you use accurate tool models it can also do the same for tool collisions. Something the Safety barriers may not tell you.
@@EdgePrecision I seem to remember being regularly frustrated with the soft limits when I was running Mazaks. We ran all Mazatrol programs, and were pretty lax on defining the tools, so that probably didn't help.
You made a comment about even though it was a 32 finish showing a pattern in the 4140. I noticed that in some I was machining this morning also. Likely has to do with the composition of the material and the affects of the heat treatment.
Honestly? The deburring was the most valuable part as far as learning is concerned. I'm not gonna be making gun drilled inconel air foils for the space shuttle on an Integrex (as awesome it is to see how that gets done!)... but damn if I couldn't use some learning on hand deburring of steel parts from a badass machinist (which you are)
Peter, always enjoy your videos. I know that they are expensive but have you considered using a spin window in front of your camera to eliminate the coolant distorting the image of the machining operation?
Good finish on the part they want to grind it after wards .. story of my life. Some times i think those who make cad drawings don't really know too much out of the office
Nice work! Not sure what CNMG insert you used on that roughout operation. I've had success with Sandvik's CNMG 543 (r.046) PR 4305. 425sfm .026 ipr @.300-.325doc. 4140 brinell of 300-310. Not sure you want to apply that amount of load on a Integrex. But a little Nexus 550 will do a great job handling those loads. The only problem is the jorgensen conveyors can't move fast enough to evacuate the big chips up the incline. So change the little sprocket, up one tooth, to increase the speed of the belt. I rough the hell out of some parts for FMC with a positive rake holder. That way I can use all eight corners of the CNMG. Grooving I usually run at 1300sfm. I saw Y'all posted a job opening!
If you have a minute, could you tell me what that tool you used to deburr your soft jaws is and where you purchased it from? I run a large hurco mill everyday and that tool looks mighty useful to me! Thanks! Great video! Im jealous of your machine!
Great video Peter! What is your experience with Espirit's machine simulation, does it provide good collision detection/prevention? Also, that deburring tool looks superb, what were you using for the tip and what are your general recommendations for pencil grinders?
Norman J , Esprit's collision detection works good if the tools and holders are properly specified properly. The grinder shown in the video I've owned for over ten years. At first I resisted buying it because of the cost. It has given no trouble it is much more powerful than a small air grinder like a Dotco but a little heavier. Even at lower RPM it has power because it's constant torque.
If you are asking what hourly rate I like to get. This is what I will say about that. Because everything I own is paid for I feel ok if I get at least $100.00 per hour. I usually do quite a bit better than that. if you were buying this machine new and had financing and insurance on that you would have to make at least twice that much and maybe a little more say $225.00-250.00 a hour.
It is possible to set limits on tools. Typically this is called tool life management on controls. It is possible to set a time limit number of use or load and than automatically change to a alternate tool. This kind of thing is done more a higher production setting. What I have to do is pay attention to the feel and sound of the tool running. With experience you can easily tell when a tool is dull or has failed and stop the machine.
Really enjoyed that thank you. To a newbie like myself I was wondering whether there are any viable options for a forging that starts you closer to the finished diameter but with the flanged end but have less material to shift? Not trying to be a smarty pants (I freely admit that I am just learning) but is the reason that it would be too expensive for a relatively small run?
Thanks Frank. This is manufactured to the customers spec. They say what material. I guess a forging would be closer but the quantity is so low they probably don't want to spend money on the tooling.
..Just found your channel today...excellent contents, especially the ones about how you got started...! What is the thread pitch on the end of these (Hydraulic?) rods....12-TPI? That's a very common pitch for hydraulic stuff no matter the diameter....you mentioned nickel plating, then ground...is that going to finished in hard chrome?...usually wears better than nickel would. Even with the CNC, do you still run a 'spring pass' on threading? I was the 'Welder' in a shop with a lot of manual machines, but we had 2 guys doing hydraulic repairs...lots of rods threaded on one end for pistons....almost always 12 TPI.......then I'd weld the rod eyes back on....we had rods up to 5-6"....! cylinders up to 10" or so....and 3 stage, 27 foot for total of 81 foot for cranes....5 stage, maybe 18-20 feet for dump trucks...
Doug Ankrum Yes the thread was a 12 pitch. After I did my work the parts got ground than electrical less nickel plated. I think there is some API spec. That doesn't allow the hard chrome plating. But I'm not sure.
Nice work and great videos. Try running the 4140 without coolant and that may get rid of the spotty look to the finish. Of course only if the insert can run dry. I run iscar ic908 with a "pp" chip-breaker dry in 4140 with great results for insert life. I also run Sandvik 4325 with a qm chip-breaker dry aswell. What kind of inserts do you use in this video?
adavid7901 , I will have to get back to you on that to be exact. The roughing insert is a Iscar one of their newer grades. The groove a Sandvik and the others Sumotomo.
Edge Precision sumitomo make great inserts for heavy milling .. in my experience i work with 50/63/80 mm shoulder mill and 45° facing . on facing on my iso40 i remove 4 mm depht on 42nicr 65% engagement at 0.23 mm/t .. heavy chip !
adavid7901, I have a better answer for you on the inserts. The roughing insert is a Iscar CNMG 432-TF IC8250 The finishing inserts are Sumitomo DNMG 432EMU AC520U Shaft OD and VBMT331ESU AC520U Pin OD and Rough Thread Relief. Groove Sandvik N132H2-0396-0002-GF 1105 Thread Vardex full profile lay down .375 IC grade VTX. These may not be the best grades for this material they are just what I had on hand without having to buy new inserts. The Iscar insert had no trouble roughing the whole part with one tip. It would have done more I just indexed it every part to be safe. The other inserts gave no trouble either.
Edge Precision I really like the sumitomo inserts in a cnmg same grade and chip breaker I run them in inconel 725 at 200sfm at .009/rev and .09 doc. And they last longer then a Sandvik ceramic. The iscar tf chip breaker is awesome aswell. I haven't used the 8250 grade but I'm sure it's great. Most of my turning with iscar was with IC908 or IC3028. I found The Sandvik 1105 grade works really good in stainless but I like the 4325 better for an all around grade. Keep up the great bids and work.
Thanks Chris. A carbide burr for most things. But I have used all types of tools. It can be slowed down to 1,000 rpm with constant torque. Its speed range is 1,000-50,000 RPM.
@@EdgePrecision Thanks Peter for the quick reply, I'm sorry I should have specifically asked you about the tip you use for de-burring post machining. I've been a manual machinist for 20 years, your videos let me into the weird world of CNC, fascinating stuff.
Do you make your own sacrificial jaws? Or buy them by the boat load? I really enjoy your videos. Not everyday you get to see start to finish process of limited run, tool room style work on a huge machining center.
No I buy blanks and machine them. It is difficult to compete with the people that make the jaws. Often times the blanks cost not much more than the material if I made them. They must buy large quantities of the material and get better discounted prices than I can get. It just isn't worth it for me to make the blank jaws. This is also why I have a CNC tool and cutter grinder and don't grind standard end mills. The price of the centerless ground blanks at the quantities I purchase. I can't compete with big manufactures. Plus the cost of coating the tools. I only grind special tools.
Thanks Eduard. The machine does have a probe. But the location of the probe is so high and to the back when deployed its hard to see when you jog the tool up to it. Also because my machine doesn't have a jog pendent (A handle jog wheel on a extension) I can't reach the jog wheel on the control and be up close to the tool setter probe to see. I find it is faster/easier to just touch off tools manually. I also like the conformation of the tools actual location (The Mazatrol shows the tools actual location in relation to the active work offset on its display) in relation to the part.
Nice work Peter. Seems odd they want a 32 finish if they are grinding and plating the part?? You mention when you were checked for tool clearance you also were looking at the sheet metal too. Does the machine have limit switches at all?
Bill De La Vega Yes it does. Mazak has barriers that stop the machine in Mazatrol but in a eia program these may not work. The machine has to travel in the Z axis further than this to make the tool change. So you can hit the chuck or the cabinet if the X axis is down to far before hitting the limit.
I know how to program and prepare cnc like this, but I fall in a limbo, I am fearful about executing my programs, because one mystake last year I lose my touch, so I start seeing videos like yours to come back, because I love this kind of work. Dont know if my english was very good, if not, Im sorry, Im from Brazil. Greetings.
If you're doing a lot of this type of work it can be helpful to set up a jig made from V blocks in a mill. I used to make a heap of drive shafts and by first mounting in the cnc mill we could machine a face on both ends to a precise length, drill, tap and cut a centre taper on both ends. Made total machine time way faster
I notice you do job shop type work. How do you decide whether a piece needs a test part or test operation? Is that cost going toward your customer? Can you make a video of how you process an incoming job through it being recieved by a customer?
If the job is complicated and of expensive material I will do a setup piece out of inexpensive material. Just to test the program and setup. I do include the cost in the job.
Normally they require the part to be roughed than heat treat than finish machine. In this case they said the material was pre qualified and that wasn’t necessary. I did ask and that’s what I was told.

Excellent work.
Very informative. Thanks.
If you have a minute, could you tell me what that tool you used to deburr your soft jaws is and where you purchased it from? I run a large hurco mill everyday and that tool looks mighty useful to me! Thanks! Great video! Im jealous of your machine!
...moc pěkná ukázka přípravy a super camera. Zdravím z Tschech. 👉 👍👍✊🙋
Josef Děkuji, vážím si toho.
Nice work again and very informative！What‘s the deburring tool?I want that too
clickblol , it's a NSK pencil grinder. Model Espert 500. www.nskamericacorp.com/product/category/Espert-500/12.
I get that weird spotty finish on aluminum and steel sometimes too.
Отличное видео!!! Лайк!!!
that HUGE dial holder, HUGE
Great video Peter! What is your experience with Espirit's machine simulation, does it provide good collision detection/prevention? Also, that deburring tool looks superb, what were you using for the tip and what are your general recommendations for pencil grinders?
Norman J , Esprit's collision detection works good if the tools and holders are properly specified properly. The grinder shown in the video I've owned for over ten years. At first I resisted buying it because of the cost. It has given no trouble it is much more powerful than a small air grinder like a Dotco but a little heavier. Even at lower RPM it has power because it's constant torque.
mind you my commentary needs improving By the way, what is the hourly rate for this machine and you driving it, it is fascinating to watch
I'm curious if it's possible to program in the geometry of the spindle, jaws, etc. so that the CAM software can help you avoid crashing...
Yes in the cam software it is possible to have a model of the machine for simulation purposes.
Great video Peter !
I wonder . What is the mazak 's cost per hour?
If you are asking what hourly rate I like to get. This is what I will say about that. Because everything I own is paid for I feel ok if I get at least $100.00 per hour. I usually do quite a bit better than that. if you were buying this machine new and had financing and insurance on that you would have to make at least twice that much and maybe a little more say $225.00-250.00 a hour.
100 ××××××× AY LOVED YES GOOD MACHIN HYDRAULIC 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
buen video..gracias por tu tiempo
Gracias de nuevo Tr Precision!
19:00 How did you know that the cutter broke, Mazak is able to detect the breakage of the cutter?
It is possible to set limits on tools. Typically this is called tool life management on controls. It is possible to set a time limit number of use or load and than automatically change to a alternate tool. This kind of thing is done more a higher production setting. What I have to do is pay attention to the feel and sound of the tool running. With experience you can easily tell when a tool is dull or has failed and stop the machine.
another great video. how fast were you turning when you faced the part. love that your videos are longer and very detailed. keep it up!
raider , l had it set to 650 surface feet with a 1000 RPM limit. Thanks.
Really enjoyed that thank you. To a newbie like myself I was wondering whether there are any viable options for a forging that starts you closer to the finished diameter but with the flanged end but have less material to shift? Not trying to be a smarty pants (I freely admit that I am just learning) but is the reason that it would be too expensive for a relatively small run?
Thanks Frank. This is manufactured to the customers spec. They say what material. I guess a forging would be closer but the quantity is so low they probably don't want to spend money on the tooling.
@@EdgePrecision thanks for the reply and thanks again for the informative video.
..Just found your channel today...excellent contents, especially the ones about how you got started...! What is the thread pitch on the end of these (Hydraulic?) rods....12-TPI? That's a very common pitch for hydraulic stuff no matter the diameter....you mentioned nickel plating, then ground...is that going to finished in hard chrome?...usually wears better than nickel would. Even with the CNC, do you still run a 'spring pass' on threading?
I was the 'Welder' in a shop with a lot of manual machines, but we had 2 guys doing hydraulic repairs...lots of rods threaded on one end for pistons....almost always 12 TPI.......then I'd weld the rod eyes back on....we had rods up to 5-6"....! cylinders up to 10" or so....and 3 stage, 27 foot for total of 81 foot for cranes....5 stage, maybe 18-20 feet for dump trucks...
Doug Ankrum Yes the thread was a 12 pitch. After I did my work the parts got ground than electrical less nickel plated. I think there is some API spec. That doesn't allow the hard chrome plating. But I'm not sure.
Nice work and great videos. Try running the 4140 without coolant and that may get rid of the spotty look to the finish. Of course only if the insert can run dry. I run iscar ic908 with a "pp" chip-breaker dry in 4140 with great results for insert life. I also run Sandvik 4325 with a qm chip-breaker dry aswell. What kind of inserts do you use in this video?
adavid7901 , I will have to get back to you on that to be exact. The roughing insert is a Iscar one of their newer grades. The groove a Sandvik and the others Sumotomo.
Edge Precision sumitomo make great inserts for heavy milling .. in my experience i work with 50/63/80 mm shoulder mill and 45° facing . on facing on my iso40 i remove 4 mm depht on 42nicr 65% engagement at 0.23 mm/t .. heavy chip !
adavid7901, I have a better answer for you on the inserts. The roughing insert is a Iscar CNMG 432-TF IC8250 The finishing inserts are Sumitomo DNMG 432EMU AC520U Shaft OD and VBMT331ESU AC520U Pin OD and Rough Thread Relief. Groove Sandvik N132H2-0396-0002-GF 1105 Thread Vardex full profile lay down .375 IC grade VTX. These may not be the best grades for this material they are just what I had on hand without having to buy new inserts. The Iscar insert had no trouble roughing the whole part with one tip. It would have done more I just indexed it every part to be safe. The other inserts gave no trouble either.
Edge Precision I really like the sumitomo inserts in a cnmg same grade and chip breaker I run them in inconel 725 at 200sfm at .009/rev and .09 doc. And they last longer then a Sandvik ceramic. The iscar tf chip breaker is awesome aswell. I haven't used the 8250 grade but I'm sure it's great. Most of my turning with iscar was with IC908 or IC3028. I found The Sandvik 1105 grade works really good in stainless but I like the 4325 better for an all around grade. Keep up the great bids and work.
Edge Precision the 8250 grade and tf chipbreaker are exactly what you should be running. Good job
good trick using the dowel pin....thanks
Good work on the jaws.
Excellent video as always. What kind of tip do you use in you pencil grinder, a burr or an abrasive tip?
Thanks Chris. A carbide burr for most things. But I have used all types of tools. It can be slowed down to 1,000 rpm with constant torque. Its speed range is 1,000-50,000 RPM.
@@EdgePrecision Thanks Peter for the quick reply, I'm sorry I should have specifically asked you about the tip you use for de-burring post machining. I've been a manual machinist for 20 years, your videos let me into the weird world of CNC, fascinating stuff.
That is what I'm talking about the NSK pencil grinder.
@@EdgePrecision Thanks
Do you make your own sacrificial jaws? Or buy them by the boat load? I really enjoy your videos. Not everyday you get to see start to finish process of limited run, tool room style work on a huge machining center.
No I buy blanks and machine them. It is difficult to compete with the people that make the jaws. Often times the blanks cost not much more than the material if I made them. They must buy large quantities of the material and get better discounted prices than I can get. It just isn't worth it for me to make the blank jaws. This is also why I have a CNC tool and cutter grinder and don't grind standard end mills. The price of the centerless ground blanks at the quantities I purchase. I can't compete with big manufactures. Plus the cost of coating the tools. I only grind special tools.
Thanks.
why didn't you ramp down on the rough milling jaws cycle using y axis?
Smart man!!
I want to be a world class machinist one day
На таком оборудовании для токаря работать - удовольствие.
Try with some sort of spinning shield (sapphire glass fine polished) , centrifugal force probably will get off coolant.
Loved your videos Sir 💟
That is a nice machine
can last all day i love to watch
Great!!
For setup thread turn why you use blocks, machine not have probe?
Thanks Eduard. The machine does have a probe. But the location of the probe is so high and to the back when deployed its hard to see when you jog the tool up to it. Also because my machine doesn't have a jog pendent (A handle jog wheel on a extension) I can't reach the jog wheel on the control and be up close to the tool setter probe to see. I find it is faster/easier to just touch off tools manually. I also like the conformation of the tools actual location (The Mazatrol shows the tools actual location in relation to the active work offset on its display) in relation to the part.
Not understand-me ,you best operator machine cnc or video?)))
Best regards from operator Anca & Rollomatic!)
nice work
That finish is from using coolant. I never run coolant on 4140 for finish passes just for roughing.
I realised that too
Nice work Peter. Seems odd they want a 32 finish if they are grinding and plating the part?? You mention when you were checked for tool clearance you also were looking at the sheet metal too. Does the machine have limit switches at all?
Bill De La Vega Yes it does. Mazak has barriers that stop the machine in Mazatrol but in a eia program these may not work. The machine has to travel in the Z axis further than this to make the tool change. So you can hit the chuck or the cabinet if the X axis is down to far before hitting the limit.
So you're loading the program from your CAM software, that is an eia program?
Bill De La Vega That's what Mazak calls a G code program. You have to save the program with a .eia suffix for Mazak to recognize it.
They make a turning holder to put the I believe B axis at 45 degrees to solve clearance issues. We use them where I work
I know how to program and prepare cnc like this, but I fall in a limbo, I am fearful about executing my programs, because one mystake last year I lose my touch, so I start seeing videos like yours to come back, because I love this kind of work.
Dont know if my english was very good, if not, Im sorry, Im from Brazil.
Greetings.
If you're doing a lot of this type of work it can be helpful to set up a jig made from V blocks in a mill. I used to make a heap of drive shafts and by first mounting in the cnc mill we could machine a face on both ends to a precise length, drill, tap and cut a centre taper on both ends. Made total machine time way faster

like a big brother? google translation
5:40 it sounds like in some scary movie : D
What kind of insert did you use to rough?
It’s been a long time ago. But I pretty sure I used some Iscar grade 8250 CNMG 432 insert. I can’t remember the exact chip breaker design.
Impressive to say the least.
Any details on that "pencil grinder" that you could post? Cheers.
Go to this link. nskamericacorp.com/product/category/Espert-500/12
I wouldn't have the guts to spin that over 100rpm... I don't know how you go 1000 plus on that diameter
Same
加油！！！
I notice you do job shop type work. How do you decide whether a piece needs a test part or test operation? Is that cost going toward your customer? Can you make a video of how you process an incoming job through it being recieved by a customer?
If the job is complicated and of expensive material I will do a setup piece out of inexpensive material. Just to test the program and setup. I do include the cost in the job.
Why would they choose a 4140 HT that big? Wouldn't the HT be gone near the center, negating even buy HT?
Normally they require the part to be roughed than heat treat than finish machine. In this case they said the material was pre qualified and that wasn’t necessary. I did ask and that’s what I was told.
