As an experienced shearing machine operator, I know that manually adjusting the blade clearance is critical for achieving precise cuts and extending the lifespan of your equipment. Proper clearance ensures that the material is cut cleanly, without burrs or distortion, while also reducing wear on the blades. In this guide, I’ll explain the step-by-step process for adjusting blade clearance on your shearing machine, including the tools you’ll need, key factors to consider such as material thickness, and tips for optimizing the machine’s performance. Mastering this adjustment can make a huge difference in both efficiency and cut quality.

Overview

1. Loosen the screws which are fixed on the blade

2. Step the foot switch and let the upper beam come down to the right position.

3. Put the feeler gauge between upper and bottom blades and adjust left blade clearance up to 0.5mm

4. Lower down the upper blade until the both blades middle areas are at the same level

5. Put the feeler gauge between upper and bottom blades and adjust middle blade clearance up to 0.5mm

6. Lower down the upper blade until the both blades right areas are at the same level

7. Put the feeler gauge between upper and bottom blades and adjust right blade clearance up to 0.5mm

8. Put the feeler gauge between both blades and move it from left to right to check the blade clearance and do some fine adjustment if somewhere is not right.
