I’m fairly new at surface grinding, and one of the things I really don’t have a good feel for is how to safely use a magnetic chuck for grinding. My grinder is a Harig 612 with a Walker 6x12 magnetic chuck.
Should all work be blocked to stop it from slipping on the mag chuck? I.e. the chuck has a couple of fences for that purpose, but what if you are grinding thin work or small work like shims or washers, or if the work overhangs the ends of the mag chuck?
What if the work needs to be supported or blocked off the grinding table, how to do it? I.e. there are no t-slots on the grinding table for clamps or t-nuts. I have some parallels that are for a mag chuck, but how do I determine whether enough magnetism is transmitted through the parallels to hold the work securely.
Can a magnetic chuck be drilled without damage to the magnetism? I recently bought a 5x10 chuck that I plan to mount on a 5x10 sine table that hinges on the 5 side. The chuck has a fence on the 10 side, but none on the 5 side, and I want to add a fence so that I can grind gib stock.
