Re: Orac Spindle Pulley Bore + Keyway size

Spindle pulley is 30mm dia, keyway is ~8mm wide and ~3mm deep (into the pulley)

Spindle pulley is ~61.7mm dia

Motor pulley is ~ 34.7mm dia

Pulley ratio is therefore ~ 1.778:1

Orac Spindle Pulley Bore + Keyway size

I was just wondering if anyone knows what diameter the spindle pulley bore is and the keyway size is?

Looking to put a taper lock HTD pulley on it with a servo motor to upgrade an indexing spindle.

Thanks,

Rob

Re: Triac PC, should I fix or convert?

Mach3 {or any other cnc + motion controller} are not going to solve your problem at all. The problem sounds primary power related to the spindle by the sound of things. so, I'd find the fuse that powers the vfd (variable frequency drive) are remove it and repower up. the machine to test it does not ...
