Our Hobbing machine obtains a high-precision and high-speed cutting capacity by utilizing a strong main body. The YH200-W has an anti-dust and anti-abrasion table with a long-time fixation rate and high-speed rotation through a dust-proof table design. The spindle has adopted a strong roller bearing structure with a high fixation rate and a great strength. In addition, as there is no thermal deformation or abrasion even under high-speed and powerful cutting, the YH200-W does not need readjusting and is available for high-precision gear processing. The control of the spindle speed follows the CVT (Continuously Variable Transmission) system and can be set to the optimal cutting speed. (The RPM can be set separately for double cutting.) Various attached functions such as jumping, double cutting, automatic cycling of the worm gear, automatic loading, unloading and crowning of processed goods, and an automatic door provide for an optimal automatic production line along with PLC control functionality.
