Mass Produces Internal Gears Precisely and Efficiently
Internal gear grinding machine ZI20A
Feature
Grinds Ring Gears After Heat Treatment to JIS Class N4 Quality
- Generation grinding is performed utilizing high-speed, high-accuracy, synchronous rotation of the wheel/work spindles.
- The barrel-shaped, multi-threaded grinding wheel improves the sliding velocity, achieving high-performance in modification of tooth flank as well as improved pitch accuracy.
- The equipped dresser conducts high-accuracy dressing of the grinding wheel as mounted on the machine.
Longer Grinding Wheel Life, Lower Costs
The vitrified CBN grinding wheel contributes to:- Longer grinding wheel life
- Reduction in grinding wheel cost
Automated Devices for High-Volume Production
- Phase matching during setup changeover is automated.
- A newly adopted non-contact sensor facilitates automation of phase matching process.
- A high-speed work changer contributes to reduced time in workpiece changeover.
