The Grinding Wheel is a record on which thrash's ultimate team of five machined parts shows up and executes to perfection... with a little punk thrown in for bad measure. But a life dedicated to metal can be a grind, hence the title of this sparks-a-flyin' record. "It just makes sense for us," reflects D.D.

Bernoulli's energy equation can be used to predict the pressure that creates the desired jet velocity. For example, a grinding wheel moving at 12,000 sfm (3,657 m/min.) requires a nozzle pressure close to 270 psi (18.6 bar) for the coolant jet to match the wheel speed. Lower wheel speeds require lower pressures.

The Basics. Before the development of centerless grinding, round parts were either ground between centers or by gripping them with a chuck or fixture. Centerless grinding requires no such workholding methods. Parts are fed between a grinding wheel and a smaller regulating wheel while resting on an angled workpiece support—a blade-like device ...

TRUING AND DRESSING. When a new wheel is installed on the grinder, it must be trued before use. The cutting surface of a new wheel will run out slightly due to the clearance between the wheel bore and machine spindle (Figure L-51). Truing a wheel will bring every point on its cutting surface concentric with the machine spindle.

(2.8) μ μ = F t / F n grinding force ratio When grinding with sharp wheels grinding force ratio is high since normal force is low compared to tangential force. Conversely, when grinding with blunt wheels grinding force ratio is low. The reader will notice that grinding force ratio is similar to friction coefficient and the same symbol is employed.
