The integrated production mode can...
Casting process is the earliest metal forming method. About 20% of automobile parts need to be produced by different casting processes. Automobile castings are mostly used in the power system or key structures of automobiles. At this stage, the production technology of automobile castings in countries with relatively developed...
The precision casting forming technology of automobile castings refers to a kind of casting forming method. The castings produced by this kind of forming technology can be directly used without cutting. With the continuous improvement of the requirements for the size, quality, precision and other aspects of automobile castings,...
The gear hobbing and tool shifting on the gear hobbing machine can be completed by manual operation or automatic control on the gear hobbing machine. Automatic control of knife channeling is most suitable for mass production. However, manual gear shifting is usually used for a small number of production...
The purpose of tool shifting of automobile gear hob is to make all teeth of hob have about the same wear degree, so as to increase the service life of hob. The position relationship of each hob tooth should be ensured during the tool shifting of automobile gear hob....
Most of the inherent accuracy of the gear hob can be destroyed. Therefore, if the tolerance of tooth profile is very small, the diameter jump of automobile gear hob must be strictly controlled. First of all, the jumping of automobile gear hob leads to out of tolerance of tooth...
