Zero backlash Rolling contact between the roller and the cam, no positive reversal backlash problem, greatly improving the ultra-precision characteristics of the roller cam, reducing the defect rate and improving the quality, which is a breakthrough for precision machining technology. Friction extrusion conduction, worm gear easy to wear and short life.
Ultra-high efficiency conduction Roller cam type turret conducts in rolling mode, reduces wear, high transmission efficiency, high speed operation, and conduction efficiency of over 90%. Conduction efficiency 50~60%.
No thermal displacement Even at high speeds, reduce friction, reduce thermal displacement, improve quality stability, and reduce non-performing rates. Accuracy reliability is not easy to maintain.
Maintenance-free Due to low wear and low aging, it can maintain initial accuracy for a long time. For the high-precision machining, the reverse direction will produce backlash, which will affect the processing quality.
Long life Roller conduction method, can reduce wear and have long service life. --
Braking performance When the brake is positioned, the disc surface will not sway back and forth, and the positioning brake will remain within 2um, which can highly demonstrate the precision machining quality. High-speed cutting is prone to process quality and thermal displacement.
