Spherical grinding machines

[DennisP]

I am looking for information on companies that manufacture the equipment, either grinding or turning, to produce spherical radii such as that found on rod ends, etc. I have an application for a machine that can produce a spherical radius of 20mm on the end of a cylinder with a surface finish of 0.8Ra Max. Can someone point me in the direction of some manufacturers of this type of equipment? Thanks.

Single point diamond turning. Steel can't be turned (but nickle plating can be).

"hard turning" is successful in some applications
