Principles of Precision Surface Grinding Services
And then there is the Y axis. On precision surface grinding machines, typically the wheels are not as wide as OD grinding or centerless grinding wheels. The benefit of the Y axis motion is that it allows a 1" thick wheel to precisely grind flat a surface that is more than 1" wide. In fact, workpieces can be many multiples wider than the ...

10 Things to Know About Creep-Feed Grinding
6. Intermittent dressing is becoming more acceptable. Because the material removal per pass is so great in creep-feed grinding, aluminum-oxide wheels used in this process tend to require continuous dressing. A dressing wheel applied to the grinding wheel as it is grinding keeps the wheel sharp at all times.
