Gear Hobbing, Shaving and Gear Grinding

Turning: The advanced high-speed Mazark turning machine are capacity manage profile turning, hole turning, keyway, threading process. Ensuring get a specific dimension and fine surface.

Hobbing is a gear manufacturing method to cut teeth into the blank with a hob, ensure high accuracy of teeth profile and lead.

Gear shaving is 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. All of our Gear hobbing and shaving realized automatic robot unit to process. After shaving, the gear accuracy can up to 7 class.

Gear grinding is the process of finish grinding gear  tooth, it is a critical step when manufacturing high precision gear. Our company put a large invest in grinding machine, most of them are advanced precision device. After grinding tooth, our gear accuracy can up to 6 class.

Forge Part Normalizing and Gear Carburization-quenching 

Ipsen furnace through carburizing to get high wear-resistance and hardness, keep the gear have more stable fine metal structure, furnace temperature can be work in 750-1000°. After carburization, gear part hardness in 56-62HRC, effective case hardness control in 0.8-1.2mm.

Continuous normalizing furnace be used of Isothermal normalizing process for finish forging parts of gear raw material. The desired metallographic structure and hardness are achieved by elimination of stress. Continuous normalizing furnace use electrical heating, the maximum production capacity can up to 840t per day, heating furnace temperature control in 800~930°, Isothermal furnace temperature control in 600~650°.

Superfinishing, Polishing and Ultrasonic Cleaning

Superfinishing process: our superfinishing machine uses the head consisting of Film Backed Abrasives stretched around contact wheel oscillated against the work piece which is held between center. This process is useful to generate surface finish Up to Ra 0.05.
