Grinding wheels for HSS
I primarly use HSS toolbits in my lathe and over the weekend I ground a number of HSS lathe bits. I use a Baldor carbide grinder with Norton 32A46 plate mounted grinding wheel. I find that I have to dress the wheel very frequently when grinding tough toolbits like MoMax. I tried grinding a 1/2 inch square stellite toolbit and it was taking forever to reshape a used toolbit. I looked through J&L abrasive selection guide and they list better grinding wheels for tool steels, but I cannot find any better plate mounted grinding wheels. (I also looked at MSC). Any suggestions on the best wheel to use for grinding HSS toolbits on a baldor carbide grinder? As a side note, greee wheels are list as non-ferrous only and I had a Norton 39C60 green wheel so I figured I would try it on the stellite toolbit. It seemed slower than the 32A46. I was tempted to try my diamond wheel but I was worried I would ruin it. chuck |
