Hello All,
Well I finally picked up a mill to set up with AC servos and Mach.
I researched the model, YCM-12, but never found anything about it. So I figured...what the heck. The price was right so I bought it sight unseen...except for a couple of pics. From what I DID find on Supermax's, I assumed this one would have a 12 or 14" Y but lo and behold..it's 16" ! EXCELLENT ! There is 1 job that I now do manually that is 14.25" Y and would have required 2 set-ups but not now.
Spent all of last weekend stripping it down and laying on a fresh coat of paint. The head is a bit noisy. The motor bearings were bad so I changed them but there is still a bit of racket. Will change all of the bearings then paint the head as well.
Ball screws cleaned up well. The end block bearings for the X are a bit rough so they will be replaced too.
The mill must have been setting a while as the quill was stuck/frozen in what looked like gum or varnish. I got it freed up then found that the yoke that connects the Z ball nut to the quill is cracked. NO prob...just glad I caught it early on.
The ways are huge boxed type and are in great shape. Turcite on the Y too.
Will need a new lube pump...looks like a forklift nailed this one.
More to come.
