Spiral bevel gear milling usually uses the method of expansion, the principle is to use the principle of gear meshing, through the relative movement of the tool and the workpiece, the workpiece is processed into the required gear shape. In the process of gear milling, it is necessary to use special gear milling machines and tools, and select the appropriate processing parameters and process routes according to the material, shape and size of the workpiece. The following are the general steps of spiral bevel gear milling:

preparation: According to the design requirements of the workpiece, select the appropriate spiral bevel gear blank, and carry out the necessary heat treatment and surface treatment. At the same time, prepare the required milling machine, tools and fixtures.
Installing the workpiece: Install the spiral bevel gear blank on the worktable of the gear milling machine and fix it with a fixture. Ensure that the installation position and angle of the workpiece are correct to ensure machining accuracy.
Adjust the machine tool: according to the design requirements and processing technology of the workpiece, adjust the parameters of the gear milling machine, such as the rotation speed, feed speed and cutting depth of the milling cutter. At the same time, adjust the table stroke and angle of the machine tool to ensure that the tool can cut the workpiece correctly.
Select the tool: according to the material and shape of the workpiece, select the appropriate milling tool. In general, spiral bevel gear milling cutter using disc milling cutter or finger milling cutter.
Milling: start the milling machine to make the tool cut according to the predetermined trajectory and speed. In the cutting process, it is necessary to constantly adjust the feed speed and cutting depth of the tool to ensure machining accuracy and surface quality. At the same time, it is necessary to use coolant to cool the tool and workpiece to prevent overheating and deformation.
Inspection and trimming: After the gear milling is completed, the workpiece needs to be inspected to ensure that its dimensional accuracy, shape accuracy and surface quality meet the design requirements. If defects or errors are found in the workpiece, it needs to be trimmed or reworked until it meets the requirements.

It should be noted that the milling of spiral bevel gears is a complex process that requires a wealth of experience and expertise. In the actual processing process, it is necessary to adjust and optimize according to the specific situation to ensure the processing quality and efficiency.
