I true diamond wheels for grinding glass by using SiC dressing stones. The kind you would use to hone a knife. To remove high spots, I cut into the flat of a SiC brick so there is full contact for about a sixth of the wheels circumference. Coming to a full stop with consistent contact pressure is also part of the dressing process. The SiC works to flatten the face and true an out of round wheel. It can take about 5 minutes of farting around to true a wheel 1/4" wide. The usuall dressing for a glass cutting wheel is to use a soft but coarse AlOx stone to clean the glass swarf from between the diamond particles. |
