RTXM11P is high precise straight line beveling machine which adopts PLC control system, and can bevel 60mm width. It specialty adopts bevelling spindle which can whole progress and also can lifting? integrally. Compared to traditional front beam or back beam's lifting, it have more simple structure、more stability、higher grinding precision's characteristic. At present this technique has applied country patent. This machine have high automatization, set the grinding parameter via the human-computer interface, the machine can adjust automatically, realize the glass fine grinding,polishing can be automatic processing in one time.
