I'm looking for some advice/ help with some ID grinding that our company is doing. We seem to be having some issues with getting a good finish on our parts and would like some help to improve our process. We are currently grinding standard Tool steel with a HRC range of min 50 to max of 58. We are using CBN plated grinding pins with a grit size of B91 (from what I've been informed it is roughly 170-200 for the grit). We can range anywhere from as small a 3mm bore with a .5 inch depth all the way up to a 42mm bore with a 1.5 inch depth. We are typically never removing more than .5mm worth of material and the part does have some interrupted grind spots.
