CNC shearing machine features: forced accurate positioning, worm drive, rod screw concentric, no noise and structural features: the use of steel plate welded structure, hydraulic transmission, accumulator return, convenient operation, reliable performance, the appearance of blade gap adjustment indicator, the adjustment is convenient and quick. A lighting device on the line, and can travel stepless adjustment of the tool carrier (optional) fence type safety protection device after the block size and the shear number of a digital display device of hydraulic transmission, tilting rack. Rack integral welding durable, use accumulator cylinder return, smooth and fast. The utility model has the function of stepless regulating stroke, the clearance of the upper and the lower blades is adjusted by a handle, and the clearance uniformity of the blade is easy to adjust. Protection fence and electrical interlock ensure safe operation. CNC CNC system and position closed-loop control system, high speed, high precision, good stability, can accurately ensure ofRear displacement precision CNC system, at the same time with compensation function and automatic detection and other additional features.
