Key Features of parker gear
material: 8620H/ 20CrMnTi    Spline Types: Involute Splines/Straight Splines
Machining method: turning, heating and hobbing
Turning:  CNC turning machine, get a specific dimension and fine surface.

Gear hobbing:  is a gear manufacturing method to cut teeth into the blank with a hob, all of our hobbing and shaving are automatic, make sure high accuracy of teeth profile and lead.

Gear shaving: removes small amounts of metal from the working surfaces of  gear teeth. correct errors in index, helical angle, tooth profile. teeth shaving process can also improve tooth surface finish. Shaving provides for form modifications that reduce gear noise. These modifications can also increase the gear’s safety and life.

Gear heat treatment: a critical step in gear manufacturing to enhance hardness, strength, wear resistance.
Technical demand:Carburizing and quenching, hardness 58-64 HRC, case depth 0.6-1.0mm

Gear grinding: Gear grinding is a precision machining process used to improve the surface finish, accuracy, and durability of gears.

Gear testing: Gear inspection ensures quality, accuracy, and performance by verifying dimensional tolerances, tooth geometry, surface finish, and hardness.
