Features of WGM360 B CNC Worm Wheel Gear Grinding Machine
1. WGM360 B CNC Worm Wheel Gear Grinding Machine is new type machine improved based on YK7236A and adopts continuous generating grinding principle.
2. Electronic gear box (EGB): WGM360 B can achieve parameters concatenation between grinding wheel rotation axis, workpiece rotation axis, workpiece axial feed axis and tangential feed axis to satisfy the requirement of dividing transmission and differential motion in gear cutting and complete grinding of spur and helical gears.
3. Continuous shift grinding: during grinding motion, the contact path of workpiece and grinding wheel is updated constantly, so it is always the newly dressed surface to grind workpiece, which increases grinding efficiency.
4. Profile and longitudinal modification: we can make special diamond rollers for dressing profile, longitudinal modification is realized by CNC controlled simultaneous workpiece radial feed axis and workpiece axial feed axis moving, thereby, all kinds of longitudinal profile may be obtained.
5. Human-machine interface: operator only needs to input workpiece parameter and related processing data before automatic grinding. Similarly, when dressing process is needed, operator only needs to input dressing parameter, which simplifies programming process and can diagnose common faults.
6. Automatic grinding cycle: customers can select manual grinding cycle or automatic grinding cycle. During manual grinding cycle, operator can interfere the clamping or unclamping of workpiece collet, terminate grinding wheel feeding motion, which is suitable for single workpiece production. Automatic grinding cycle is suitable for batch production. Broad grinding wheel and tangential shift guarantee workpiece accuracy and consistency.
7. Automatic dressing cycle: achieve grinding wheel multi-start dressing; grinding wheel cover can turn over automatically to reduce labor intensity.
8. Air blowing clean (optional): workpiece can be cleaned by air blowing to avoid pollution from coolant.
