At this time the hob has cut tooth shape 50-60m. When the wear of the hob side edge is close to "value", please regrind the hob in time.
4. Gear grinding
1) Grinding speed, feed, stroke times and grinding depth can be reasonably selected according to the modulus, number of teeth, material, hardness of tooth surface, precision grade of HARMONIC reducer CSD-32-100-2UH of Hamenako Precision Mill, roughness requirements of tooth surface, material, particle size and hardness of grinding wheel, etc.
2) Grinding teeth should be divided into rough grinding and fine grinding. Csd-32-100-2uh, rough grinding depth is not more than 0.02-0.04mm for grinding hard teeth and gear; During fine grinding, the cutting amount should be small, and the grinding depth is between 0.005-0.02mm to ensure the surface quality. shall be polished without feed.
3} After rough grinding of the first gear of the same batch, the accuracy of tooth orientation and tooth shape shall be checked. Harmonic reducer CSD-32-100-2UH of Hamenako Fine Grinding Machine shall be adjusted until qualified, and then fine grinding shall be carried out. This is called a minor adjustment. See grinding gear adjustment section for details.
4) In rough grinding of the knife, small adjustment, shape adjustment alignment, pay attention to the knife spark meet the requirements.
