Adopt 20hard alloy saw blade and auto-spray lubricating and cooling system, ensures high cutting linear velocity and high surface finish quality and high accuracy. The saw blade may rotate from -90~0~+67.5, extended cutting range. Adopt straight forward type feeding, hydro-pneumatic damper stepless speed governing system, ensures smooth feeding. Can realize vertical cutting through adjust the rear positioning shelf when at -90 degree. CNC control of the saw blade feeding height and digital display of the rotating angle degree. Adopt the imported integrated plc control, with the self-measuring and self-diagnosing function. The circuit is of high stability and nice environmental applicability and can upgrading by long distance operation through net-works.
