CNC Double Mitre SawSQJ2 500F for window machine Forsawing sorts of aluminum profiles for doors windows and curtain walls by cutting at any angles between 22.5 degree to 135 degree. High quality servo motors are adopted. LCD touching display screen for operating control, through which the cutting lengths and angles are inputted. The automatic positioning for profiles length and angle is available. Saw straight outgoing mode, connected parallelly with hydro pneumatic control system, so as to ensure the feeding stability of the saw blades at stepless speed. The two sets of clamping cylinders clamp the profiles from two different directions horizontally and vertically, that makes the clamps more reliable. Attached holding rack makes clamping easier.
