The main characteristics of a gear grinding machine are:

1. The machine tool structure is relatively simple and easy to operate and adjust.

2. The contact surface between the grinding wheel and the gear rack workpiece is large, and the grinding force per unit area is relatively small, resulting in uniform load.

3. The grinding stroke is slow and the grinding amount is large.

4. The contact line and meshing line of the grinding wheel and gear rack do not coincide, resulting in smoother transmission and low noise.

5. The efficiency of forming grinding teeth is generally 3-5 times higher than that of generating grinding.

6. The forming gear grinding machine can adjust the precision of the rack tooth surface, and the tooth surface roughness is significantly improved compared to the developed teeth.

7. This type of gear grinding machine has a wide range of applications.

The forming gear grinding machine is equipped with different spindle diameters and installed with different specifications of grinding wheels, which can process both ordinary gears and gears with steps. For gears with a small number of teeth, especially those with less than 10 teeth, it is easy to machine on a forming grinding machine.

The tooth alignment modification of involute profile modification is easy to process on a forming gear grinding machine and can achieve high-precision modification requirements. The forming gear grinding method can achieve the possibility of multiple rack modifications, which is an important advantage of this modern advanced method. Although there are different mechanisms to achieve modification on the forming gear grinding machine, adjustment is cumbersome and difficult, and the smoothness of the modification curve is not as good as that of the forming gear grinding machine.
