The main components of cemented carbide blades are tungsten carbide and cobalt in different proportions. The original form of the raw materials is powder; a container Cemented Carbide Inserts weighing about 560kg contains the prepared raw materials, which will be used to produce different powders; in the workshop Here, the dry raw materials are mixed with a solvent made of ethanol and water to form a gray paste with a consistency similar to yogurt; after the paste is dried, the sample is sent to the laboratory for quality testing; these powders are composed of many It is composed of particles with a diameter of 20-200μm, which are very small (the diameter of a hair is 50-60μm).
The stamped cemented carbide blades need to be heated to harden. This work is completed by a sintering furnace, which can process thousands of blades at a time; the pressed blade powder is heated to about 1,500°C in a 13-hour process. It melts and becomes cemented carbide, which is a very hard material; the shrinkage ratio in the Carbide Milling Inserts sintering process is about 50%, so the blade size after sintering is only half of the previous one.
