A brief discussion on the key factors of precision casting gear processing

The key factors of precision casting gear processing are analyzed as follows:

In the process of gear processing, advanced blank forming processes, more stable and precise heat treatment processes, and particularly suitable surface hardening procedures are all key factors in the final formation of high-quality gears. For example, there are several key links in grinding processing: only by selecting a grinding wheel with a sharp edge and low grinding surface stress, the grinding feed rate can be increased, thereby shortening the grinding time. This To improve grinding efficiency, the interval between grinding wheel dressings must also be extended to reduce costs.

Design is a key step and the initial step in precision casting. For gear casting, design is also a key step. It is related to the quality and level of the cast gear. In the design stage, more appropriate casting gear materials are selected and carried out. Advanced and reasonable structural design, selection of efficient and reliable gears and bearings are indispensable links.

On the premise of ensuring that there are no grinding burn cracks and ensuring quality, it is necessary to use higher grinding parameters as much as possible to shorten the grinding time, thereby improving the grinding efficiency, increasing the output, and ensuring its accuracy, Reduce surface roughness. By using a more suitable grinding oil, it can ensure good lubrication and rust prevention, which is more conducive to reducing the surface stress of the grinding tooth surface, avoiding burn cracks, reducing roughness, and reducing the degree of blocking of the pores of the grinding wheel. , to ensure that the grinding wheel is sharp, thus reducing the dressing of the grinding wheel, reducing the amount of grinding wheel and reducing costs.
