note
· The main motor transmits power to the spindle through the gear reduction box and universal joint.
· The lift of the upper cutter shaft is controlled by the servo motor, which accurately controls the overlap degree of the upper and lower cutter and accurately displays the adjustment clearance value.
· The spindle round cutter and sleeve are locked by hydraulic nut, equipped with nut protective sleeve and sharpening tool.
· The unit is equipped with two round shears and a switching table for the round shears.
