Worm grinding machine manufacturers believe that the grinding machine is mainly used for finishing the tooth surface of hardened gears. Some gear grinding machines can be used directly to grind small module gears on tooth blanks. The grinding teeth can eliminate the deformation after quenching, and the machining accuracy is high. After grinding gear accuracy is generally not less than 6-4 grade. There are two kinds of gear grinding machines, namely, forming grinding teeth and spreading grinding teeth. Forming grinding machines are rarely used, and most gear grinding machines are developed. There are two types of continuous grinding teeth and indexing grinding teeth.

(1) Worm gear grinding machine manufacturers believe that the working principle of continuous gear grinding method is similar to that of gear hobbing machine. The grinding wheel is worm-shaped, equivalent to a hob. It performs a spreading motion relative to the workpiece, grinds the involute, and then grinds all the teeth with the feed motion.

(2) Worm grinding machine manufacturers believe that this grinding machine can be divided into three types according to the shape of the grinding wheel: disc grinding wheel, large plane grinding wheel and conical grinding wheel. Its working principle is basically the same. It uses the meshing principle of rack and gear to replace the rack and gear with a grinding wheel to grind the gear tooth surface. The rack tooth profile is straight, the shape is simple, and it is easy to trim the sand profile. When processing, the gear to be ground rolls on the imaginary rack, and one or two teeth can be ground every time it rolls back and forth. Therefore, multiple indexing is required to grind the entire tooth surface.

Worm grinding machine manufacturers believe that after more than 80 years of development, the grinding machine has developed from a single product to multiple series and multiple specifications, from traditional mechanical development to numerical control technology, from alumina grinding wheel to CBN grinding wheel, so that the accuracy and performance of the machine tool And the processing efficiency continues to improve, and the operation becomes easier and more convenient. The research and manufacture of gear grinding machines in my country has a history of more than 40 years. Since the early 1980 s, it has developed rapidly in the past 20 years, and has produced seven series of gear grinding machines with more than 60 specifications.

Worm grinding machine manufacturers believe that with the development of science and technology and economy, the performance requirements of gear processing machine tools in the gear processing industry are also increasing. On the contrary, the gear processing machine tool manufacturing industry plays a guiding role in gear processing, forming an organic linkage development. To this end, a number of new products that can adapt to the pace of social, technological and economic development have emerged; otherwise they will be eliminated. This is particularly prominent in the gear grinding machine manufacturing industry.

Worm grinding machine manufacturers believe that the forming wheel grinding machine has been developed for more than 40 years, and the key to this grinding machine is the forming wheel dresser. Before the 1980 s, most finishers were circular steel belt structures, four-bar linkages, and involute templates. However, when grinding helical gears, the profile of the sand must change with the diameter of the grinding wheel, and it is difficult for the mechanical dresser to achieve random changes. However, this kind of grinding wheel has poor versatility and high manufacturing price, and has not been promoted. It is ideal for use with CNC grinding wheel dresser. When grinding helical gears, the trajectory of the dresser can vary with the diameter of the grinding wheel.
