After many hours of researching. I had reached the conclusion that I needed a CBN wheel for grinding HSS in my surface grinder. I contacted a company called Eagle Superabrasives. They specialize in CBN and Diamond wheels. They agreed a CBN wheel is what I need for grinding HSS however felt my machine was lacking with only a 1hp spindle. I would not see much benefit for the 5 times in price over an AO or Ceramic wheel. Here are my questions. Has anybody ground HSS using a CBN wheel? How does it perform compared to an AO or Ceramic? Do you think a 1hp machine would be under powered for removing .005" total material per side? I have 48 parts to grind. Even if I could only take .001" per pass I would be happy. Im taking .0005" per pass right now and I have to dress the wheel every couple passes. I want to be able to grind at least 2 parts at a time and do a couple sets before dressing again. Is there another type of wheel that works good for HSS that you have used other than a CBN?
Here is a few wheels I have tried.
Radiac 8BP46 G800 VOS
Radiac 8BP46 J8 V8
Radiac RA46 H8 V8
Radiac 8BP46 H800 VOS
Norton 5SG46-JVS
I use Q Cut 225C cutting and grinding coolant with water.
I have tried slowly dressing the wheel with my diamond and also dressing it more aggressively. In addition to this thread I have emailed Norton about my issue and am anxiously waiting to see what they have to offer.
Thank you for any help.
