Base on the basic PSM series general grooving machine, PSM-CNC series is developed by changed the driven type and control system. CNC system is specialized digital-controlled software for roll processing. Jinan Power Rubber Roller Equipment Company and the institutions of scientific research develop the software. Its professional performance characteristics are the best among the machining industry. Due to the all-round of the system function, it can make almost all the profile of rollers. For instance, parabolic crowning and concave, cosine crowning and concave, circular, cone, coarse pitch, herringbone, diamond, straight groove, horizontal groove and other formations in the appended drawing.
