CNC Hob Relieving Grinding Machine
■ Introduction
● Advanced CNC supporting the precise and complex mathematical calculation
● Fine quality cast bed, 5/4 axes with 3 axes interpolation movement
● Linear axes motion using the linear motor and encoder for closed loop control
● Torque motor table as part axis with encoder for closed loop control
● Electronic cam and gear technology ensure machining accuracy and speed
● Flexible tooth profile interpolation online dressing
■ Applicable scope
High-speed steel / solid carbide hobs profile grinding containing finishing/pregrinding/preshaving/preskiving/skiving gear hobs、timing pulley hobs、sprocket hobs、(involute/triangle/rectangle) spline hobs, (bore/shank) radial/tangential worm hobs、 disc milling cutters and various non-standard hobs.
