Shear Blade Grinding

The frequency of sheet metal shear blade grinding depends upon the operational cycle, a workload of the blade, and the shearing material. During the shearing process the material is sheared along the whole length. That is why a shear blade interacts with the cutting material a lot. A dull metal cutting Guillotine Shear Blade has to penetrate the material further requiring a deeper force. Additionally, a blade with small cracks or lost sharpness leaves a less desirable cut.

Cut quality is directly proportional to the sharpness of a shear blade. It is vital to know whether you shear blade has the reversible edges. If this is the case, then you can turn the blade over, and have the benefits of a total of 4 cutting edges. However, if the blades have been flipped before, then you have to sharpen them.  You can send them to us and we will sharpen both surfaces and all four cutting edges, so you can flip/rotate the blades later.

Shear blade grinding must be performed at the right angle. Higher angle grinding must match the specified blade angle for the shearing machine model and cutting material density. If the pitch is too shallow or too steep, it can affect the cutting performance.

Our experienced team grind every blunt metal shear blade to a new sharp edge.

  • We can regrind and resharpen blades up to 6 meters in length.
  • MASTERCUT provides a comprehensive metal shear blade grinding and sharpening services from our premises in Chesterfield.
  • Being located in the heart of the UK allows us to serve customers almost across the whole country, providing collection and return services. So wherever your company is located, our sheet metal shear blade sharpening service is near you!

Sometimes, a blade is badly chipped or has been re-ground for more than 1 mm of the original manufactured thickness. This  ‘width’ reduction causes difficulties in fitting the blades, thus we will not advise shear blade grinding service. In those cases, we offer a new set of a replacement guillotine shear blades. We offer shear blades that suit all worldwide shear machinery including Amada, Edwards-Pearson, Haco, Cincinnati etc.
