Spherical Grinding/Turning

Spherical Grinding/Turning

Spherical Grinding/Turning

(OP)
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? I've also posted this in the bearing forum with little response. Thanks.

RE: Spherical Grinding/Turning


You could try these people:

I used one of these thirty years ago and it was pretty good if you took care to get the tool at exactly the right height.

Or try a Google search for "Radius turning attachments". There are loads drawings and patents for making attachments and some leads to professionaly made second hand items like this one:

I also noticed an Indian firm that offers a similar new product. All of these would be dependant on the centre height of the lathe you want to fit them to, but in some cases a smaller one could be packed up to suit.

Hope this helps
