What Is Single Point OD Grinding? : Modern Machine Shop

The grinding wheel's angle of attack presents an edge of the wheel that makes the contact between the wheel and workpiece tangential. High Speed Cutting The relatively small contact area between the single point grinding wheel and the workpiece reduces the cutting forces generated by the metal removal process.

How It Works – Centerless Grinding | Today’s Machining World

As it turns, it pulls the bar past the grinding wheel, so no external feeding mechanism is required. Each abrasive grain on the surface of the grinding wheel takes a little bite of material every time it passes the bar being ground. This produces a lot of heat, of course, so the grinding area is flooded with a generous flow of coolant ...
