The 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.

Consequently, the workpiece surface is finely finished and grinding precision is high. Though the grinding force of this type is higher than the shedding type, it is lower than other loading type and glazing type. The grinding wheel and working condition are to be selected so that such the grinding as this is usually performed as grinding work.
