Hello.
we hope to release lathe CNC 12 on or around October 4th.

they were custom machine one off jobs.. the engagement mechanism is not for resale. basically there are two schemes for low buck C axis that work. One is engaging and disengaging the belt to the servo that connects to the spindle, this can be achieved in a number of different ways and is most common...

Two basic questions. Is it feasible to use a servo motor from the 0-10v signal and a voltage to pulse converter? Is it possible to use one of the axis to control the spindle? Thanks in advance. Clay Ps. I already Ave a spare servo, but do not have a 3 phase spindle motor or VFD available. Clay, It ...
