Knee Mill Conversion
« on: July 01, 2014, 05:21:39 AM »
Hello all,
           I had this Knee Mill conversion before and decided to put the Dc servo back again. I need some help on step/unit calculation:
The ballscrew pitch = 5mm
Gear ratio: 1:4 (the gear on the dc motor side is a T18 and the ballscrew left side is a T72 aluminium timing gear)
The encoder used is a US digital E5kit, encoder CPR = 500





thanks,

Thread starts is the number of individual (separate) threads on the screw -I would assume your is single start.

Lead is the calculation of how many mm the nut moves for one complete revolution of the screw.
