Makin' the parts that make the parts! It's been a long time since I've been in a machine shop, but I love watching everything. Thanks for taking the time to share it with us. :)
Many thanks from Yorkshire UK. Just woke up and watched your video. Very appreciative of you taking time to share your experience from clearly a busy schedule.
Thank you Peter. When you video making a tool with your CNC cutter grinder it is breathtaking. Your explanations make me feel I could (almost!) step up and make an endmill. Dreaming... I wish you had a manual tool and cutter grinder and, with your usual casual but accurate way, showed us peons how to sharpen various cutters. If you know of any youtuber doing T&C videos... guidance is, would be, appreciated! Keep safe.
for me this is the best TH-cam channel worthy of watching, if there was such a thing as an award or an Oscar, you earned it. keep making those videos and keep us machinists happy. just a suggestion, combine all your videos into a library and offer it for sale .
Ooooooooh great opening shot , was hoping for Part 2 of the last video... Awesomeness. Now having watched this, this is like the BEST video ever -from 26 mins onwards amazing shots and almost complete explanation. Incredible. This video has been a HUGE share. Thanks for Sharing Peter ! (I don't think there's anything else like this on the Web).
@@EdgePrecision Can't wait (in a good way) to see how you figured out a finishing solution for those deep very tricky surfaces and edges in titanium. There was a sort of teaser graphic in the background of the last video... (your customer should be very pleased indeed.). Really appreciate the thought and care you put into these videos, . some really good shots, angles , close ups and lighting that actually visually communicates what's going on. ~ That's rare / difficult to achieve.
Using a micrometer to measure a sharp carbide tool will almost certainly damage the cutting edge. Rocking the indicator tip on a sharp cutting edge will also damage it. It wouldn't be noticeable with the naked eye necessarily but with a microscope or Zoller measuring machine you'll see it clearly. Maybe not a big deal for some but I just thought I'd share that.
My K O Lee T & C grinder sucks badly in comparison to this. Really there is no comparison. If I can get it running within half a thousandth TIR, I'm tickled. No way to grind flutes from scratch! Re-sharpen I can do, but not as nice as this can. And get the 1st and 2nd relief so perfect on a chamfer mill, the 2nd relief always seem to drag as it gets close to the center of the endmill. I keep trying for improvement. Thanks for sharing Peter. KenS.
In those days they were dealing with HSS tools. So they could machine it in the annealed state than heat treat. Than just grind the cutting edges as you would today on a manual tool&cutter grinder. Or it could be done with a cam operated machine as well.
I find it remarkable you have such command of the nuanced detail of the process and the software, to make a one off tool. I realize you have had this for years but I have tools that I use once in awhile that I take as long to rediscover as it is to use them... And didn't you say there were only 4 of these machines made??? GREAT video. thx.
que buen trabajo y vaya pasada de maquina de afilado...como siempre un placer seguir tu canal..gracias por compartir tu conocimiento..un saludo y mucha salud
Usually, we use wire cutting to cut off point drill to get a chamfering mill. Then use a USB microscope to magnetically attract the spindle to measure the diameter of the tip of the new chamfering mill
Cool video and nice endmill. It is also possible to measure the diameter with the machine when making new tools. For this purpose, the option "measuring in process" is necessary. With this option, the core diameter and the outer diameter can be measured and automatically corrected.
Who knew there was such a beautiful end mill hiding inside that bar of carbide? How close of tolerance can you get with this setup? Is there a cycle for dressing the wheels? I worry who is going to be doing this work in 10 - 15 years? Thanks for making the video clip.
Yes if the tool has the correct spacing for the mic. But modern tools now days sometimes have irregular spacing on the flutes. I have a 3 flute mic but not anything else. Say for 5,7 or 9 flute tools.
The inconel job on the horizontal mill is setup to run unattended. I have run that job for years and thousands of parts. I have shown a little about the cutters I use in a previous videos.
Wow! I like to own such a machine! Serious toy for big boys. I'm afraid I cannot afford it but this gives you a lot of freedom in your machining approach. I saw an earlier video when you ground a special tool for a job and I thought you used the Mazak for this too. Now I understand better. This machine probably has air or oil bearings and automatic balancing to get a real thru running tool. Do you own this machine or is it a machine you can use for your jobs? Software looks a bit dated but it seems to have all the features you need for grinding special purpose tooling. (DOS was really stable compared to a lot of windows versions who came later. Win97 made my hair grey...) Thank you for sharing, Job (for grinding only a Deckel SO1 which provide me great single lip cutters for custom jobs but this machine rocks!)
Thanks Job Kneppers! I own this machine. It's a CNC tool and cutter grinder. It actually rides on roller bearing ways. It theoretically can resolve to .000039" of accuracy.
Hi,I trained as a cutter grinder in the early 70s.Man how it changed,what would you charge for one endmill like that? WOW.I still have a old cinn grinder in took apart and moved in my celled over 20 years ago and thought I would sharpen tooling someday
Starting from someone’s tool it takes more work to get the chamfer to the exact size. It only takes about 20 min for this machine to grind it from solid.
Superb video thanks Peter. Such a versatile machine too, choosing the right machine is a skill also it seems. When buying a used machine do you inspect the machine yourself for condition or just trust the dealer ? If buying at a distance I wonder if the are surveyors to carry out the assessment?
I use a Walter's power, endmills are the easier tools we make we are specialty tool company and make some complicated cutting tools.. well a Walter's hmc 500 if anyone is interested in seeing it
Really interesting video, Peter =) It's become quite rare for me to watch a 30min youtube video and feel like it only took 5 minutes. Have you ever considered taking in an apprentice? I'm in the EU and already a machinist (although I'll never reach your level) so I'm sure there's bound to be some people who'd love to come under your wings and learn the trade. Cheers.
I do exactly the same type of work but on manual machines. I could make the entire tool on manual machines . I can't compete time wise to the CNC making the tool from a blank . We would buy a new end mill and add the chamfered. The chamfered l would put it on with the Hybco form relief grinding fixture. The chamfer would be just as accurate with a better finish and I wouldn't need a secondary. I have made some metric extra long drills from carbide blanks as they were a non catalog item. Was a lot of work and time. They sure looked beautiful when they were done. Your CNC can do somethings l can't . You can flute taper end mill with a constant 30 spiral. I would need to change the rate of spiral down the flute to do that. Never had the opportunity to run a CNC but I'm sure I could learn but at pushing 70 that's not likely going to happen.
I can see how it can be done on a manual grinder. I have done some regrinding. But I would not want to make one from a blank. My hats off to you! Also I will be 66 in July. Your never to old to learn something. Thanks for the comment.
Oh I am still learning on the manual machines. Anyone that thinks they know it all in this business is nuts. I sill learn from others and on my own. I been grinding for over fifty years and l found grinding is a moving target. When I started they didn't have CBN wheels.
You don't worry about it. That's funny. Don't get my wrong. I think what are you doing is amazing. Like I just have a bench grinder. Actually I have 3 and a half grinders. The half is a old sowing machine motor. With grinding wheels buffing wirer. Ect .
Hi, Thank you for the great video! How do you resurface your wheels? We have the OD grinder redress them but I've heard of wire cutting the wheel, even wiring in a form into the wheel.
Great video. The sound quality of your voice is perfect. I stopped making videos at work because I received so many complaints about my audio. Interesting software. I wonder if we sat side by side, you with your software and me with the ANCA software, which might be faster creating the same tool. My guess is it would be very close. One thing I didn’t see, after you changed the wheel pack and coolant manifold I didn’t notice you telling the machine that it had a different pack. Is this not necessary with your software?
Thanks Alfred. Yes I did do that. It is necessary to tell the software. I just didn’t get it in the video clip for some reason. But it’s just a selection before you select to manufacture and probe the clamping length. It will give you a error saying no wheel pack in the machine configuration for that cycle. Probably the same in Anca software. Though I have never used Anca. My version of Numroto is probably 15 years old. It may be a lot different now.
On the “geometry” page you entered .624” diameter, then on the “blank” page you entered .625”. Does that interfere with the grinding or finished product?
The blanks are really .6247” centerless ground. All endmills are really .001-.0015 undersize. For grinding it makes no difference what size you enter. The machine will try to grind that size.
I'm not even a machinist and I found this fascinating. Nice explanation of your program. Also how often do you have to check the grinding wheels for accuracy? How long do they last?
Grinding wheels get shaped by a diamond in the machine, and very frequently. On our CNC grinders they're touched up after each part. There's a "dressing" cycle that shapes the wheel against this diamond point, and an offset is created each time.
How can we encourage one of the big manufacturers to give Peter a brand new machine with all the bells and whistles to keep until he retires. That’s what everyone in this community wants to see. The cost would be a fraction of what they didn’t spent going to IMTS. I would like to see it done with some support/training/tech/ to get Peter up to speed and no strings attached. Assuming you (Peter) are game. Let’s start mentioning this to our reps and see if we can make it happen.
Very cool What make + model of machine is that? Did you ever upgrade the software on it? I want to get one of those grinders on the used market to play with. I know nothing about them.
Hey Peter! How many end mills can you typically produce using one pack of wheels before you need to dress or replace? I haven't had a lot of experience with grinding and interested in the different types of wheel bonds and how they hold up.
These wheels have a lot of abrasive depth and are very hard. I don't grind production type of work. But if I had to guess I would say thousands and thousands. It depends on how hard you push them and how much you true/dress them. If you are grinding tools that require very sharp internal corners. Than you would have to true up the wheels more to maintain the sharp edges. I haven't bought any any wheels in years.
About the focusing. If you are using a static placement for the camera, turn autofocus OFF. There's really no reason for the camera to change its focus. Even during zoom (optical or digital) the focus will not change.
Thank you Rudi. I do understand how to use manual focus. As I said in this video. I was trying out a new camera. The Sony ZV-1. I accidentally had it set on the product showcase function for the auto focus. If I was using my Canon 6D DSLR which I should have been using I would have eliminated this problem. It is because this Sony's point and shoot camera's manual focus is a pain to use. But the sound it records is better than the Canon even with the Rode Go mic. I wish Canon put better audio amps in their cameras. But I just got this Sony yesterday and wanted to try it out. I like the camera but it doesn't do so good for this purpose. It lacks the ease of using manual settings. For a Vlog type of camera I think it will be fine.
The wheel pack that looks copper (they are 3M wheels) isn’t. It has some kind of plating on it. The others (the ones I used) are Naxo Force wheels. I’m not sure what there cores are but it isn’t aluminum. It may be steel or stainless of some kind. The cup wheels are aluminum but not the fluting and gashing wheels.
most diamond wheels are nickel plated its one layer of diamond powder, some are resin bond resin impregnated some more expensive form wheels are reverse bond with metal powder bond, you need a dressing stick to clean the wheel not a (carborundum wheel dresser) do not try to dress wheel with a diamond you will ruin your diamond wheel.
You mentioned customer. Without revealing any secrets, is this like a local shop you are making a special tool for some specific special job he has? Because I am just curious why someone would call Peter instead of Niagara (or whoever) for an end mill.
it would be cool if and when you made these tools after its made you showed it in action cutting somthing unless the cutter was for some 1 elese love the vids
Was the fluting operation at the normal feed rate and "depth of cut." I know nothing about grinding, but if so that's an incredible material removal rate
With this size endmill you can take it in one cut. Let’s say for endmills .750 in diameter and smaller. For larger you may take more passes. These wheels are specially designed for this kind of grinding.
@@AnselGaddy Yes if you are running a run of endmills it will change as well as the machine and coolant changing temperature. But for one tool not to much. These wheels don't wear fast.
So do those wheels just cut straight at full depth? A typical table grinder that I'm used to, those things only do recommended depth about a hair at a time.
Да, но эта машина была построена 20 лет назад. А его программному обеспечению не менее 15 лет. Я уверен, что новые версии NumRoto намного более продвинуты.
Sir did you ever make a conical ball end mill. I want that you make video on this. If you have already made video on this please send its link to me. Thanks
Yes I have ground tapered ball endmills before. In fact that is part of the standard program on the grinder in the Numroto software. But I don’t think I have a video on that.
Or even slower because the material has to flow out thru the gashes. This is where a lot of people break endmills while milling. It is better to plunge at a angle or helix if possible.
dear sir, i just buy a Makino Seiki CNJ4 2011. I would like to study how use it to make tools. Do you have any training course? or you know where i can study about that please give me a suggestion. thank you very much

Fantastic machine Peter. You have a whole other business just with it. Making high end tools for the Houston area. That would keep you very busy!
Looks like it turned out great!
Beautiful tool.
If I could afford it I'd have you knock off another one so I could encase it in acrylic and put it on my bookshelf.
Now that's is precision cheers.
Amazing work we need more videos like this
Awsome video! Nice that you share such educating stuff! :)
Beautiful finish …u got 3 wheels on there .. that’s awesome … do all operations without changing wheels ..😱
"it only measures half of a tenth, but that's good enough"
"I wasn't confident with the measuring probe thingy so I made a tool that will measure a millionth of an inch runout.... " 🤦♂️🙄🤔
Well done, very impressive!!.......... 👍.
really good video of each step, thank you
I need a machine to make drill bits too.. love it
Magnificent! Thank you

You can get an anvil mic to measure odd flute end mills I’ve always done it that way.

Is there any advantage of a Grindingwheel with a copper body ? Because we in Germany only have them with a Aluminum body or I never seen one.
The wheel pack that looks copper (they are 3M wheels) isn’t. It has some kind of plating on it. The others (the ones I used) are Naxo Force wheels. I’m not sure what there cores are but it isn’t aluminum. It may be steel or stainless of some kind. The cup wheels are aluminum but not the fluting and gashing wheels.
most diamond wheels are nickel plated its one layer of diamond powder, some are resin bond resin impregnated some more expensive form wheels are reverse bond with metal powder bond, you need a dressing stick to clean the wheel not a (carborundum wheel dresser) do not try to dress wheel with a diamond you will ruin your diamond wheel.

This tool is for Center-line. The shop I Useto own and where I’m located and rent space from. The job they are using it on I have run before myself.
@@EdgePrecision Makes all the sense in the world. TY for the answer.
it would be cool if and when you made these tools after its made you showed it in action cutting somthing unless the cutter was for some 1 elese love the vids
Was the fluting operation at the normal feed rate and "depth of cut." I know nothing about grinding, but if so that's an incredible material removal rate
With this size endmill you can take it in one cut. Let’s say for endmills .750 in diameter and smaller. For larger you may take more passes. These wheels are specially designed for this kind of grinding.
@@EdgePrecision do you have to compensate for wear on the grinding wheels as a program goes along?
@@AnselGaddy Yes if you are running a run of endmills it will change as well as the machine and coolant changing temperature. But for one tool not to much. These wheels don't wear fast.
Thanks for your effort, in fluting prosess when you use flat wheel and when angle wheel?
Thanks
It’s used for more flutes at a higher helix angle. Like a 6 flute endmill with a 45 degree helix angle.
So do those wheels just cut straight at full depth? A typical table grinder that I'm used to, those things only do recommended depth about a hair at a time.
Yes these super abrasive wheels are designed to grind this way.
A creep feed grinder cuts full depth as well
Do you send them out for coating or do you run them uncoated? If so, what materials are you cutting with them?
If I need a tool coated there is a place here in town that does it. Most of the time I use uncoated tools. But coated works better.
Работал на более современном станке ANCA RX7 там вообще без проблем такой инструмент изготовить
Да, но эта машина была построена 20 лет назад. А его программному обеспечению не менее 15 лет. Я уверен, что новые версии NumRoto намного более продвинуты.
Is this CNC tool grinder yours or is it Centerlines?
My grinder not Centerlines.
Sir did you ever make a conical ball end mill. I want that you make video on this. If you have already made video on this please send its link to me. Thanks
Yes I have ground tapered ball endmills before. In fact that is part of the standard program on the grinder in the Numroto software. But I don’t think I have a video on that.
Thanks for showing. M
Since it has 2 flutes that center cut do you have set the feedrate as for 2 flutes when plunging?
Or even slower because the material has to flow out thru the gashes. This is where a lot of people break endmills while milling. It is better to plunge at a angle or helix if possible.
Sir which CBN wheel used for flute grinding and OD in end mills production.
This is a carbide tool. So I’m using diamond wheels.
dear sir, i just buy a Makino Seiki CNJ4 2011. I would like to study how use it to make tools. Do you have any training course? or you know where i can study about that please give me a suggestion. thank you very much
Sorry but I don’t know anything about this machine or it’s control. All these machines have different software.
