A 500mm axis, above steps, 1) car - > mill. Both sides of the thimble hole how processing? If the blank line is not very good condition
Are you afraid of the way the material deformation processing or have deformation if the former, can add fixation in the bar (three points), it can effectively reduce the torque, improve the overall rigidity of material processing, but need some complete processing of the latter, no way, look at your allowance enough for you deformation
In this way, the two holes must not be on the axle line
The bar at both ends of the top ends of the lathe topping pinhole, bar, with chuck clamping rod drives the rotary dial movement turning circular grinding machine.
Well, is this also the problem, R hole is dry this, and then better, repair the top pin ah...
