Re: [CAD_CAM_EDM_DRO] Ball-screws

Hi Jon,

I have a tool and cutter grinder, which I use mainly as a 12" surface
grinder, and a tool-post grinder. Is there any reason why I must use angular
contact bearings. Can't they be Timken taper rollers.

I don't quite understand your description of how the bearing block should be
designed and what about the other end? If one end of the ball-screw is fixed
with no axial movement should not the other end be just a plain bearing or
ball-race.

It is my intention to keep the handwheels and dials, fitting the encoder and
motor drive pulley to the other end out of the way (X axis). The only
problem I can see with this arrangement is protecting the motor bits from
cuttings and cutting oil.

Regards,

Terry
