How to Adjust the Blade Gap of a Gantry Shearing Machine

First, stop the machine and disconnect the power to ensure it is in a completely stationary and safe state, avoiding the danger of sudden starts during adjustment.

Clean the blade surface and surrounding area of material residue and oil to prevent impurities from affecting adjustment precision and operational safety.

Prepare the necessary adjustment tools and consult the equipment manual to familiarize yourself with the location and operating principle of the blade gap adjustment mechanism.

Check the blades for wear, chipping, etc.; if damaged, repair it first to avoid affecting the gap adjustment effect.

The blade clearance needs to be determined based on the material type and thickness of the material to be sheared.

Refer to the equipment manual for the corresponding material type and clearance compatibility requirements to clarify the target range for this adjustment.

A feeler gauge can be used to initially measure the current blade clearance to determine the adjustment direction and range, avoiding blind operation.

Locate the clearance adjustment mechanism on the side of the machine or where the blades are fixed, usually an adjusting screw or knob.

Using a special tool, slowly rotate the adjusting component, maintaining smooth movement during rotation, while repeatedly measuring the blade clearance with a feeler gauge, gradually approaching the target value.

If jamming occurs during adjustment, do not force it; check for obstructions or worn parts.

After the clearance adjustment is complete, tighten the locking mechanism to prevent clearance changes during operation.

Restore the equipment power, select a small amount of material to be processed for a test shearing, observe the flatness of the sheared surface, and check for burrs, twisting, or other defects in the material.

Finally, record the material type and corresponding gap parameters used in this adjustment for future reference in similar processing.
