Grinding

Motion of the charge in a tumbling mill • At relatively low speed the medium tends to roll down the toe of the mill and abrasive grinding occurs. The medium is said to be cascading leading to finer grinding and increased liner wear. • At high speed the medium is projected clear of the charge parabolically before landing on the toe of the mill. The medium is said to be cataracting leading to comminution by impact

Grinding (Machining)

Current grinding technology includes form grinding, which may be performed with a cubic boron nitride (CBN), aluminum oxide, or ceramic wheel. The advantage of this type of grinder over generating-type grinders is better speed, tooth spacing, and tooth finish, along with highly controllable lead and involute.

GRINDING FEEDS AND SPEEDS

Dec 15, 2016The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

How grinding wheel is made

Throughout the grinding wheel's history, the bond that holds the abrasive grains together has proven as important as the grains themselves. The success of grinding wheels began in the early 1840s, when bonds containing rubber or clay were introduced, and by the 1870s a bond with a vitrified or glass-like structure was patented.
