◆ Generally, plating is used as the surface treatment for gears.

◆ The materials commonly used for gear machining include aluminum alloy, copper, titanium, stainless steel, etc.

Material selection: Gears can be machined from various materials such as steel, stainless steel, aluminum, or brass, depending on the application requirements.

Gear cutting: Gear cutting is performed using specialized CNC gear cutting machines, such as gear hobbing machines or gear shaping machines. These machines use cutting tools to remove material and shape the gear teeth according to the desired specifications.

Gear shaping: In gear shaping, a specialized CNC gear shaping machine is used to shape the gear teeth by progressively removing material. This process is often used for producing external spur gears or internal gears.

Gear hobbing: Gear hobbing is a process where a gear hob is used to cut the gear teeth. The gear hob is a specialized cutting tool with multiple cutting edges. During gear hobbing, the gear blank and the rotating hob are engaged, and the hob gradually cuts the gear teeth to the desired shape.

Gear grinding: Gear grinding is a precision machining process used to achieve a high level of tooth surface finish and dimensional accuracy. CNC gear grinding machines use abrasive grinding wheels to remove material from the gear teeth and improve the gear's surface quality.

Gear inspection: After the gear machining process, the gears are inspected using specialized equipment, such as coordinate measuring machines (CMM) or gear measuring machines, to ensure they meet the required specifications and tolerances.

It's important to note that the specific gear machining processes and equipment used can vary depending on the type and specifications of the gears being produced.
