Centerless sphere grinding?
Centerless sphere grinding?
(OP)
Can anyone point me to a link (or provide a short description) of how a centerless machine is set up to grind spheres? I've found references to use for billiard/bowling balls etc, but no concrete info. It is my understanding that this is not the same process used for bearings (rill-filing/plate lapping not sure of name, but concentric grooves on counter-rotating plates...) but closer to conventional wheel-regulated centerless grinding.
Trying to visualise how sphericity is acheived on a setup that can grind short plugs with no barreling. My suspicion is that the wheel axes aren't parallel but...
This is a general interest question btw. I have a project on the go that piqued my interest.
Thanks! This site looks like a great resource.

It is made with grinding wheel grooved in sphere radious but with a great angle in the axle , and a little ball instead the blade .
