So after finishing the retrofit of the old Miyano gang lathe the spindle bearings are shot. You can grab the spindle nose and push it side to side about .0005" to .001". The cut quality is also fairly bad. Just cutting a spring pass on an aluminum bar shows a lot of chatter like marks.
I can also measure a .0005" to .001" axial play by pushing on the face or the collet closer of the spindle. Not to mention there is roughness and fairly loud bearing noise while running. I expected this but I'm looking for someone that can refurbish it or any advice from others that have done this before. I haven't ever sent anything out to be rebuilt so I'm ignorant on the process. One online quote I received was 4500 to 6500. Is that reasonable? Does anyone know of someone or have pointers? I'm not opposed to trying to do it myself but I know it would be very challenging to get it right. I'm sure I'd need to order 2 sets of bearings... One for the first attempt and one to get it right!
