Using Grinding Versus EDM to Finish Form Tools

However, there are some PCD tools that require a ground surface finish, as there is a small degree of thermal damage using EDM. Even when running the EDM unit at a low speed—the faster the more thermal damage and the rougher the tool finish—with the right spark generator settings, surface finishes of ±1.5 microns, for instance, cannot be achieved.

Trying to get an Ra 32 finish without grinding

17-02-2020· A 32 finish is a nice finish, but does not require grinding. I personally would think a 16 would. If you are turning with a decent nose radius and a fine feed, providing your machine is not imparting any glitches[like if you were using the compound manually with no finesse, you should meet a 32 with at most a quick hit with fine emer

How to Use a Surface Grinder Machine

A surface grinding machine is used to produce a smooth accurate finish on either metallic or nonmetallic materials. It uses a round rotating abrasive grinding wheel that remains stationary (but rotating) while the feed table (with work attached) is run in a reciprocating motion (left and right) under the grinding

MACHINING TIPS: Critical Aspects to Grinding -

11-01-2017· A grinding wheel with a rougher grit will remove more material per pass, but the result is a rougher surface finish. A finer grit will remove less material per pass, but give you a smoother finish. The drawback to a finer grit is the potential for clogging of the wheel and over heating of the plastic which results in burnishing or burning of the surface.
