Old post here but I just had to reply.
We dress diamond and CBN in 2 main ways. Using a common bond wheel (sand wheel) rotating at a slow RPM or on a brake truing device (brake keeps wheel running slow). Norton makes a brake truing device as well as rotary dressing systems using diamond rolls.
I run manual grinders along with Jungner CNC tool and cutter grinder. I have installed several of the rotary dressers but I still use the arbor in the workhead running about 100 rpm to dress with as well. Diamond rolls can be used to dress formed wheels with extream accuracy. |
