According to the way of toothing:

1. External gear honing method: Use the external honing wheel to honing the transmission gear of the external transmission system.

2. Tooth type combined honing method: use the inner honing wheel to honing the transmission gear of the external transmission system, or use the external honing wheel to honing the transmission gear of the internal transmission system.

According to the type of pressure:

1. DC transformer honing method: adjust the initial pressure before honing, and then fix the management distance. As honing progresses, the pressure gradually decreases until it is nearly dissipated. This method can correct the shaft sleeve force of the transmission system a lot, but the load of the honing wheel is large, and the honing tube is easily damaged. This kind of method can be maintained in general shaving machines.

2. Shapely honing method: During the whole honing process, the honing wheel and the cast iron part maintain a steady pressure. This type of method corrects errors with diligence and high efficiency, and the honing wheel has a long service life, but there are requirements for the honing tube to maintain a DC power supply, which can be maintained by a four-column hydraulic mechanism or a heavy hammer type. The hydraulic transmission system software has different types of structures and operating specifications.
