Features
Highly accurate cutter grinding
- It adopts a casting bed with excellent damping properties. The grinding wheel spindle is driven by directly connecting a flat motor to a high-rigidity spindle unit that uses high-precision angular ball bearings.
- Our original traction drive reducer is used for the reducer of the cutter spindle, and extremely smooth rotation is achieved without harmful vibrations.
Highly accurate cutter grinding that can make arbitrary gear profile
- All-axis full CNC control with 0.1 micron resolution has been achieved.
- The 2-axis synchronous machine control of the cutter axis and table axis related to generating its motion applies CNC synchronous control technology for gear cutting machines that we have developed over many years and achieves higher precision than previous products without a pitch block or split plate.
Shortening of setup change time and trial cutting adjustment time
- First workpiece: Input the required data and the setup calculation and setup change are executed by the CNC.
- Repeated workpiece: Simply call up the data and then the setup the machine; the setup change is completed instantly.
- It predicts the roundness of the gear profile that occurs during bias correction and automatically corrects the roundness of the gear profile.
- Wet processing that does not cause grinding burn can be possible even for high efficiency processing.
Completely "skill-free" with CNC
- The experience, intuition, and tricks that were previously required for gear work are no longer required.
- Five types of grinding wheel molding work (tooth profile, relieving, outside diameter, runout and back face of grinding wheel) can be completely managed by the CNC.
- The CNC can control the accurate value of griding wheel's outer diameter and tooth profile.(Tooth profile is derived from dress teaching function.)
