Circular saw with metal ceramic blade

Circular saw with metal ceramic blade

There are more and more difficult materials used on wide range of application, which are poor thermal conductivity, good toughness, with higher content of Cr or Ni, but difficult to process. Most people use cobalt tungsten carbide cutting tools, but the processing effect is not good.

In this case, the work piece is composite metal material containing Cu and Ni 50% shown as below:

The customer use carbide tipped circular saw which contains Ni 50%, caused that the middle of Cu cannot be removed after machining. For solving this problem, BW develops a new cutting saw -- metal ceramic brazed circular saw blade. After testing, the new type is obviously more effective than old one. The finished products may meet customes’requirements.

Characteristics of metal ceramic blade:

  1. The cutting edge is with self-sharpening effect of re-grinding.
  2. Stable chemical results.
  3. No infiltration effects on the blades.
  4. There is no pollution by using Co as the metal bonding material, instead of the mixture of Ni and Co.
  5. More safe during processing.
  6. Wider applications.
  7. Increasing the surface finish and accuracy.
  8. Enhancing the continuous processing capacity.
