- Sometimes a Bridgeport's big brother can be used for something other than outboard support or holding a cup of tea.
Machining bars in preparation for welding to auger boring machine skid. There were six, ten foot long pieces to machine. I have recently been swamped with work and I need to get this done quickly. I was able to machine the feature in one pass which saved some time. The milling cutter is a 3" Sandvik R390 face mill with six inserts. Turning at 800 RPM and fed at 20 inches a minute. The cut was 1" wide and 5/8" deep. I could machine about 43" in a pass and then reset the bar and continue on. Each bar required three resets and took a total of about 15 minutes to complete.
I don't believe I have ever seen a cut like that done intentionally and successfully! What a machine! Thanks.
Thanks Bruce. This was my first proper 'heavy' milling machine and I have been pleasantly surprised by what it can do. Ken
First glance I thought it was aluminum then I saw the blue chips. That's getting some work done
I said to myself:
Now that's working!
Must be near full insert depth of cut.
Nice chips, the colour of money, blue..
Rigid machine and se up.
I'm sure Mr Wilkes will be impressed.
I was using just about the entire insert on the depth of cut. When you do that you get every penny out of your inserts. Unfortunately you don't get many opportunities to do that. Ken
Thanks for the video, I saw your other videos - very helpful to me. I'm also glad I “discovered” you on TH-cam - you are a top professional and also have a special personality, an example to many. Continue.
Thanks, Ken
Show off. I love that you send er all the way tho. Hoggin is a blast.
very good video..thanks for your time
Nice one Ken . One decent size cut there ! Cheers .
Thanks Max.
With out coolant ....this is impressive
That was very satisfying, thank you!
BTW forget about David's milling he amazes me with his trepanning.Milling inconel 718 is hard enough yet he punches a huge hole through a big billet.
very impressive...wow
Just come across your video remind me the good old days working on a big Mecoff mill machining long work pieces.Just wondering why you didn't climb mill,less friction less heat longer tool life.Unless your machine pulls into it.
Hello Mehemet, Your last sentence is the reason I didn't climb mill it. The backlash eliminator on this mill is worn out.
Bloody hell 😨, impressive !.
Did you make that radiused wiper yourself? That's pretty sweet. Good to see someone taking good care of such a nice old machine.
Sort of. The metal wiper holder was original to the machine, but I replaced the actual wiper by bending a straight one into the correct radius. It worked better than I had hoped. Ken
What face mill and inserts? WOW
Now David is gonna try to do the same. Just wait for it.
I'd like to see him fire up that Huron and bury a face mill in some large stock. Ken
Oh that support stand for the Bridgeport.you say...haha....when lock down safe is declared an the pubs are open..js as a David wilks representive...cheers..
Is that a #50 milling machine taper in that mill? I like how you used the 1-2-3 blocks for a backstop.
Hello Mark. Yes it is a 50 taper spindle. Ken
Good job! I love gear head mills I just love running my Cincinnati vertical she's a beast. Best wishes Mark
@@markmilam3152 What size of Cincinnati?
Is that machine a Fexac by chance ?
WOW!
Every machinist in my area will take you a bridgeport can't really cut! They use these only to drill molds. I am after a Bulgarian FU321 with 7.5kW as an upgrade to my uncle's FU251. Apart from tiny drill presses with milling capabilities that's the only true mill for many of the machine shops in my are like the also Bulgarian ZMM lathes (C11 lathes are really getting shit done although I like the TOS a little better in some regards).
Very impressive, What make is your mill ? It seems to have a good length to the table. I have a Bridgeport 2S myself.
The mill is a Fexac. They were made in Spain. The longer table is nice, so is the fact it has 5 tee-slots instead of the usual 3.
@Foxberg's Fabbercobblin Yes, it has 10 hp on the spindle. Ken
Holy chips batman! That looked so cool 😎
Any particular reason coolant wasn't used?
I didn't use coolant because I would have had a hell of a mess (it would have all ended up on the floor with the swarf) and I wasn't looking for a good surface finish (this was a weld prep). The face mill got pretty warm but was not damaged and the inserts seemed to hold up well. Ken
@@hmw-ms3tx Makes sense. I saw the flying chips but didn't realise the mill wasn't in any sort of enclosure. I wouldn't want to clean up that mess either 😂😂
And if the inserts were only warm after all that, they're a particularly good match for the material & horsepower.
Like they say, put the heat into your chips, not into the tool!
Did I see the lights flicker when the cutter engaged the work? :)
In my old shop that would have been a distinct possibility. Ken
Ouch....material wear and cost for power probably are equivalent to a one week holiday in the Caribbean :-)
Not at all CNC's use more power than manual machines.
Lovely painted clamps! 😅
Thanks Robert. That was the colour they came with and I haven't used them enough to wear it off. Ken
What inserts were you using?
Think I would be putting a wheel barrow and some ply wood to direct it into the barrow.
More chips than KFC well done
Funny, I thought about putting my wheel barrow under the shower of swarf. However, it is very awkward to empty it into my scrap metal bin. Ken
@@hmw-ms3tx less to pick up off the floor lol
Wow, so quiet. Bridgeport would rattle like hell trying to take 1/4 of the cut
How much HP did that cut take?
It was probably between 9 and 10 hp. The mill has 10 hp on its spindle, so it was near its limit. Ken
Nicee!
Thanks, Ken
I bet you don't get your inserts from Bangood!😤
Not these ones. Actually not any. Ken
Sharing on Facebook, wow is all I can say.....
That cut makes Abom look like a wussy!
I guess he doesn't read comments
