Lathe Mechanical E-Stop
My M250 lathe was originally fitted with a mechanical E-Stop assembly on the rear of the motor.
It is a shaft mounted plastic disc between two plates, one fixed, one floating axially against axial springs.
The stationary electrical control winding pulls the floating plate, so the assembly is electric release, spring apply.
The brake was rated 415 Vac and connected directly to two motor phases.
The brake was tested at 240 Vac as Ok, but never used because it just sounded "wrong" to apply such forces to the headstock gears.
The forthcoming delivery of a new Powtran VFD prompts me to complete the VFD installation, including getting an E-Stop functional.
The VFD is complete with dynamic brake.
What other style of mechanical brake is used on lathes ?
What experiences can anyone provide to help me sort out an acceptable arrangement ?
I made a dividing plate for the lathe that clamps directly to the spindle outboard end.
It looks like a ventilated disc off a pedal/motor cycle.
Is this approach viable ?
Look forward to any suggestions made,
John.
