View Full Version : I'm Still Amazed by the Machine

At work I program and run a Mazak Intgrex 400 CNC machine.
Todays job was making pins for a crane.
4140 material that called for grease holes drilled 13 1/2" deep.
It was programed to drill the holes pecking .100 at a time, and drilled 10 of
the holes without sharpening the bit. I've been at this a long time but the
machine still impresses me. And then I think about it. It wasn't drilling a
13 1/2" deep hole. It was drilling 135 holes .100 deep.
Naaaa it STILL impresses me!:cool:

That machine is a trick unit, I am sure none of us home shop guys will ever have one.

Sure it's a "trick machine" and I wouldn't want one at home!
I was joking with a Mazak rep that I wanted one that was about 9 X 20 for
my home shop. He said he could fix me up, but I might have to sell my house
about 3 times to pay for it.
Who wants to show off something they made with the line,
"Look what I programed!" I know there are a few home CNC fanatics, and
that's great! Programing is a challenging hobby, as well as a rewarding job.
But, at home it's slow, manual and perfect. Not always on the first attempt,
but who cares? Taking a block or slug of material and turning it into
something is a craft bordering on art. For 10 hours a day, working for the
man, it's stress. For 4 hours a night working for me it's relaxation.
It's much more rewarding to make it one cut at a time, than it is to write a
program and watch to see how the machine interprets the instructions.
It's also cheaper! If I run into the chuck at home the damages are an $8
drive belt. If it happens on a multi million dollar machine at work, you might
as well just dig a hole and crawl into it. :eek:
