Hello,
I need some advice on centerless grinding. I took a position as a lathe hand at a machine shop and after the lathe work was done they put me on a centerless grinder. I have never ran one of these machines. I was shown the basics and now I’m pretty much on my own. The machine is a Cincinnati EA, and I think the plain bearing type. We are trying to grind 286 hardened stainless rod, about 5/8 diameter. I have the regulator wheel set at 0 degrees. The blade is brass, blade angle is 20 degrees. I’m not sure what is meant by diamond offset. How to I determine how to adjust this? We have tried 3 or 4 different grinding wheels and have been unable to pull more than .005. Presently we are using a silicon carbide wheel on the softer side and of medium density. I have no experience with this type of machining but I’ve done some research and tried to apply it to the job. I’m not sure what kind of wheel to try next and I would appreciate any advice from anyone who has run these machines. I understand they are very accurate and efficient if set up correctly but I can’t seem to find much information on proper set up. We do not have an owners manual. Also, are there any safety issues I should be concerned about?
Thanks for your time.
