" Holistic welding structure treated by annealing. " The top rest does the linear motion under the hydraulic cylinder¡ ¯ s drive. " Both the upper and lower blades are rectangular£ ¬ and the blade clearance can be adjusted manually or by electricity rapidly. " Time relay controls shearing stroke and shearing angles are adjusted electrically. " The forward and backward movement of the back gauge is motorized and indicated by a digital display£ ¬ while fine adjustments are also available. " All major electrical and hydraulic elements are assembled with high grade international brands. " A light alignment device makes shearing much easier and more efficient. " Pneumatic back support is optional. CNC Machines Only£ º " CNC system controls ram and back gauge movement. " Blade clearance, shearing angle and shearing length are calculated and controlled automatically by CNC system.
