1. It uses ultra-fine grain WC-Co powder for low-pressure sintering, and has the characteristics of high hardness, high strength, good wear resistance, and sharp cutting edge.
2. The internal metallographic structure of the product sintered at low pressure is dense, which effectively reduces the microscopic pores in the alloy, avoids the phenomenon of edge chipping during fine grinding and use, and improves the finish of the cutting section.
3. The grinding requirements of the fiber optic cutting knife edge are extremely high. Generally, a high degree of automation is required to grind the edge with a precision optical grinder. Only in this way can the finely ground edge be sharp without the advantages of edge chipping and curling. The edge requires high processing precision and high finish to achieve a mirror effect (Ra≥0.012). The cross section of the cut optical fiber is flat and smooth without burrs.
