Cemented carbide CNC blades are the "teeth" of the CNC lathe industry chain. A CNC lathe must be equipped with a dozen or more kinds of CNC blades. Nowadays, the fashionable key commodities in the sales market are all imported. There are few self-produced and self-sold carbide tool bits in my country, and neither the production volume nor the quality can match the import sales market. The cemented carbide manufacturing industry is a new technological industry chain. There are only more than ten years of scientific research on cemented carbide in my country. The industrial production force is weak, and the construction of scientific research personnel and product development infrastructure is poor.
my country is the country that exports the most aluminum alloy grinding wheels. A lot of rare earth materials must be used in the processing of cemented carbide tool heads, but at this stage, the technical strength in our country is far less than the excellent technology abroad. Only export the raw materials overseas, and then buy back the cemented carbide made overseas. If it is not possible to develop and manufacture independently in our country, then everyone will be "hijacked" by the aluminum alloy manufacturing industry.
