Center distance of the shafts for the motor and leadscrew on my lathe are just a bit over 77mm. Motor shaft is 3/8". Screw shaft is 10mm. (Yup, surplus parts, ya gets what there is.) I want to do a 2:1 reduction, which with 1/2 stepping the 200 step motor will get 0.02 mm move per step from the 16 mm per turn ball screw. It's a 9x20 lathe and the motor is a Slo-Syn brand, label says 450oz holding torque. Specs on the motor say 5% accuracy so I wouldn't expect 1/16th stepping to consistently produce 0.01 mm movement with a 2:1 reduction.
There's very little adjustment on the motor mount so I'll likely need to use a smooth idler against the back of the belt. There is room where I could put an idler on the inside of the belt and use some arbitrary length, but shorter belt = stiffer and better accuracy, right? Recommendations on pulleys, tooth profile and belt length / number of teeth? I have lathes so I can ream a 3/8" out to 10mm. ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
