Flap wheel as a kind of large emery cloth wheel, it has the advantages of safe operation and high grinding efficiency.
In the process of using flap wheel grinding tools, when the grinding grints are blunt, due to the grinding grits themselves part of the fracture or adhesive fracture, the grinding grain from the grinding tools local or completely off, and the grinding tools working surface abrasives constantly appear new cutting edge, or constantly exposed new sharp grinding grains, so that the grinding tools for a certain time to maintain the cutting performance.This self-sharpening of the abrasives offers high accuracy and greater flexibility. In some special machine tools, such as the processing of nozzle special machine tools, the impeller on the use of hydrodynamic bearings. When grinding the chuck, the tolerance of the positive roundness is between 0.2 and 0.4mm. The advantage of the linear motor is that the cutting time is shorter and the positioning time is saved. The linear motor can move at a speed of 30m/min and a speed of 3m/s2.
Abrasives by raw material source, there are two kinds of natural abrasives artificial abrasives.The only natural abrasives commonly used in the mechanical industry are whetstone. Artificial abrasives are distinguished by basic shape and structure features, including grinding wheel and flap wheel
