Re: For Sale - Lathe ATC suit Orac

Hi,
I know this is a very old post but did you sell the tool changer?
If not do you still wish to sell it?
All the best Calgone

Re: Orac stepper motors.

Hope this helps.

Siemens Micromaster 410

Hi,

My Siemens Micromaster 410 has broken.

They do not make it any more.
Can I use a Siemens Sinamics G110 inverter w/filter, 0.37kW

I use it on my orac lathe spindle motor.

Any help would be great.

Re: Spindle encoder screw size?

Hi,

It could be BA?
As some of the screw threads on the machine are BA.
2.7mm could be 6BA

Hope this will help.
