Abstract
Process of grinding and polishing flank surfaces of teeth of toothed wheels, which includes a grinding device, a polishing device, a dynamic positioning device, and a toothed wheel.
Claims13
A process of grinding and polishing a flank surface of a tooth of a first toothed wheel, comprising:
- a) providing a first toothed wheel, providing a rotational grinding device for grinding a first portion and a second portion of a flank surface of a tooth of the first toothed wheel;
- providing a polishing device comprising a stationary axis and a polishing body rotatable about the stationary axis, the polishing body being for polishing flank surfaces of teeth of toothed wheel;
- and providing a dynamic positioning device for holding the toothed wheel and for dynamically adjusting position and attitude of the toothed wheel, relative to the stationary axis, during polishing;
- b) grinding with the grinding device the first portion and the second portion of the flank surface of the tooth of the first toothed wheel;
- c) removing the first toothed wheel from the grinding device with the dynamic positioning device;
- d) positioning with the dynamic positioning device the first portion of the flank surface in contact with the rotating polishing body such that the first portion of the flank surface is polished by the polishing body;
- and
- e) adjusting position and attitude of the first toothed wheel relative to the stationary axis, such that the second portion of the flank surface is polished by the polishing body.
