CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

To many customers, they can easy to get how to adjust the clearance of upper and lower blades of small model  hydraulic guillotine shearing machines . How every, it's do hard for them to adjustment big models like QC11Y-40*2500 mm or QC11Y-40*3200mm. It is an important factor that affects the cutting quality and prolongs the service life of the blade. The correct adjustment of the blade thickness depends on the shear plate thickness. The machine tool converts the blade gap value to the plate material value directly on the gap dial. The clearance between the upper and lower blades of the shear should be the same throughout the entire length. This shear shall be equipped with a supplementary tool holder on the worktable to be used as a micro adjustment of the uniformity of the gap between the upper and lower blades. The minimum clearance before adjustment is 0.05 mm at the factory. The user should not change easily during normal use. After the blade is used for a certain period of ...
