After entering the 21st century, my country's spiral bevel gear machine tools have entered the stage of full numerical control, and gradually developed towards high precision and large machining diameter. It can not only process high-precision spiral bevel gears with a diameter of more than 1000 mm, but also independently build a closed-loop production line for digital processing of high-precision spiral bevel gears, changing the situation that all CNC spiral bevel gear machines in the past depended on imports.

High-precision spiral bevel gear is a key transmission component in the automobile, petroleum, energy and aerospace industries, and its theory, design, processing technology and innovation ability are an important symbol of a country's manufacturing development level. At present, the spiral bevel gear industry has begun to combine high-precision spiral bevel gear technology with computer technology and intelligent manufacturing technology. New and more mature theoretical designs, processing and heat treatment technologies and new materials continue to emerge, and the quality of spiral bevel gears continues to improve. my country's research on spiral bevel gears is relatively late, so it is more necessary to improve domestic spiral bevel gear technology through continuous innovation to meet future challenges.

In theory, the large-scale high-precision spiral bevel gear machining technology requires three necessary conditions, namely the determination of the pressure parts, the determination of the helix angle and the cutting of the tool radius. They are the basic structure of the gear, in terms of the radius of the cutter head, pay attention to the installation position. The installation of the cutter head is mainly based on the rotation of the cutter body, and the oblique line is the side view. The movement of the tool is also an important part. It is a technical method of a parallel device with an eccentric roller as the core, and special attention should be paid to the position of the tool. This is based on the fan-shaped turntable, with the moving parts box as the carrier, and is processed in the axial direction. It is also important to adjust the position of the cutter head. Each knife face has a balanced cross-section, and the location of the cross-section point is the center of the machine that carries the machining gear. The manufacturer should move along the axis of the bed base and install the sector overall shape on the rollers. The installation standard should be carried out with the angle of the Bell gear adjusted according to certain parameters. This parameter is mainly obtained by the mechanical gear on the milling machine. We use designed gearing.
