How to really cut 4140 - with a Gorilla

We spent a day with Dan McMurray from Alpha Industrial Supply trying to break his tools. Bottom Line, we could have, but decided to stop once we hit 482 ipm feed rate in 32Rc 4140. You heard that right. Those sound like common feed rates for Aluminium, but it was 4140. We also slotted a 1/2” Endmill, 3/4” Deep in that same 4140, ran it at 47 ipm at 4800 RPM’s. The finish was incredible. Dan has been looking for machines he could really load up his tools on and show what they could do. He stressed that there best fitted for a CAT50 machine with a ton of torque. He was amazed that our little VMX24, CAT40 12k Spindle took it like it wasn’t even there. It wasn’t until we hit that 482 ipm that we got above 80% spindle load. Have a look.

My story begins 4 months ago when a life long friend approached me asking if
I ever thought about starting my own business.  I had been around lasers and
plasmas my whole life but never thought about getting myself a mill and
lathe.

So in January, I contacted a company and the salesman sounded great
but he lacked communication.  So I gave up on that company and that is when I
turned to Gage Machine Tool.  I called and within a week Dirk(the owner) and
Chad his trusty salesman came and had a lunch meeting with my wife and me.
Not only were they super knowledgeable of the machines and tools, but they
brought with them an actual controller off of a machine.  That had me sold
on the spot.  It was so easy to go through the steps to get a high-quality
part.

So after we got approved and the machines were delivered March 6th.
I purchased the VM10i and the TM8i, they were so tough looking.  We had to
wait a couple weeks for me to get the correct power put in (no 3 phase
direct) I have to run off of a 50hp phase converter.  Then 2 service techs
came and had them hard installed in a matter of hours.  The following Monday
Chad Waldo came and the next 3 days he and I put in some long hours.  He
wanted to make sure I was super comfortable running and programming both the
mill and the lathe that he stayed as long as I wanted him to.  

He came back in 2 weeks and was very surprised to find I had been
doing such a great job.  How could you not with such an amazing machine!  I
still have questions from time to time but rest assured Chad and his staff
are super eager to help!

I would recommend the Hurco brand and Gage Machine Tool to anyone and everyone. Such an easy machine to work with to get critical tolerances within .0005 of an
inch.
