The key factors of precision casting gears are as follows:
In the process of gear processing, those advanced blank forming processes, more stable and precise heat treatment procedures, and particularly suitable surface hardening treatment procedures, these are the key factors to ultimately form a fine gear. For example, in the grinding process, there are several key links: only through the selection of sharp grinding wheels with low surface stress can increase the grinding feed, which will shorten the grinding time, which It is to improve the grinding efficiency and extend the grinding wheel dressing interval to reduce costs.
Design is the key step of precision casting and the initial step. This is also a key step for gear casting. It is related to the quality and level of the gears that are cast. In the design stage, select the appropriate casting gear material and carry out Advanced and reasonable structural design, selection of efficient and reliable gears and bearings are indispensable links.
Under the premise of ensuring no grinding burn cracks and ensuring quality, it is necessary to use as high a grinding parameter as possible to shorten the grinding time, so as to improve grinding efficiency, increase production, and ensure its accuracy, Reduce surface roughness. By using a more suitable grinding oil, it can ensure that under the premise of good lubrication and rust prevention, it is more conducive to reducing the surface stress of the grinding tooth surface, avoiding burn cracks, reducing roughness, and reducing the degree of plugging of the grinding wheel pore , To ensure the sharpness of the grinding wheel, this is to reduce the grinding wheel dressing, reduce the amount of grinding wheel, and reduce costs.
