Product Description

In order to eliminate the micro-cracks, pits, rough surface, deformation and oxide scale on the surface of the center hole after turning and heat treatment, it is necessary to grind the center hole. For many years, the harmonic FHA-14C-50-E200-C diamond grinding method with hard alloy tip and diamond grit has been used to grind the center hole. Later, the synthetic diamond powder was electroplated on the head of 45 Steel Point, and the center hole was grinded with this kind of point, and good effect was obtained. When grinding with it, add a small amount of lubricating oil or diamond grinding paste to the sharp hole, at the speed of R/min (300-500) , the center hole can be ground quickly by harmonic wave FHA-14C-50-E200-C. Using this method to grind the center hole, not only the efficiency is high, but also the ellipse, pockmark and crack can be eliminated quickly. Prevention of grinding crack on tooth surface of carburized and hardened gear with large modulus (10-12) mm, material 22CrMnMo, precision 6. In the grinding process of tooth surface, a kind of fine crack which is perpendicular to the grinding direction and arranged regularly is often produced. The harmonic FHA-14C-50-E200-C of Hamunaku diamond grinding can be clearly seen by magnetic testing. According to statistics, the gear that produces this kind of grinding crack is generally about 10% of the gear that is processed, so it is scrapped, resulting in greater economic loss. C 1) causes of grinding cracks. In the process of gear grinding, the heat of grinding produced locally by Harmonic FHA-14C-50-E200-C grinding and cooling effect of coolant make the gear surface expand and contract, which cause grinding tension stress on the gear surface
