Toycen-Cuttermaster Professional Radius Air Spindle with Radial Drive
For those who may need to grind a sphere on the end.
I’ve created an oiled bush motorized insert for the Radius Air spindle.
This is a conversion kit, so one can use the radius air as a linear air bearing or a radial driven motorhead for grinding spheres on the end of an HSS or carbide rounds.
Just remove the tool spindle tube and there is a bushing that slides in to protect the air bearing bushing, replacing the inner surface with an oiled ground and honed bushing suitable for close tolerance radial grinding.
The Gear motor is a 24 v planetary 50 to 700 rpm with a 3 to 1 belt reduction Spindle speeds from 25 to 250 ish
