The Carbide Cutter Teeth manufacturing process involves multiple complex steps, from raw material selection to finished product processing, each of which requires strict control to ensure high performance and durability. Here is a detailed look at the Carbide Cutter Teeth manufacturing process:
1. Selection and mixing of raw materials
Carbide Cutter Teeth are mainly composed of hard compounds of refractory metals (such as tungsten carbide WC) and bonded metals (such as cobalt Co), and sometimes titanium (Ti), tantalum (Ta) and other elements are added to improve performance. These raw materials are mixed through ball milling, drying, screening and other processes to form a uniform powder.
2. Powder pressing
The mixed powder needs to be formed by pressing process. The pressing process includes wet grinding, gluing, drying, granulation and other steps to finally press the powder into the desired shape of the blank. The pressing pressure is usually up to 12 tons to ensure the density and strength of the billet.
Step 3: Sintering
The pressed blanks need to be sintered. Sintering is the heating of the blank at high temperatures (usually 900 ° C to 1500 ° C) to near the metallization temperature, so that its grains grow and form a dense structure. During the sintering process, the bonded metal reacts with the hard compound to form a strong bond.
4. Mechanical processing
After sintering, the tool head needs to go through multiple machining processes, including centerless grinding, cylindrical grinding, sharpening, etc., in order to achieve the required size and shape. In addition, it is possible to carry out the process of segment difference grinding, tool grinding, etc., to ensure the accuracy and performance of the tool head.
5. Coating treatment
In order to further improve the wear resistance and service life of the tool head, a thin film material is usually coated on the surface of the tool head. The coating process mainly includes chemical vapor deposition (CVD) and physical vapor deposition (PVD). The CVD coating was carried out at 900℃ for 30 hours to form a coating 2-12μm thick; The PVD coating delivers the metal source target to the tool head surface via a gas carrier.
6. Welding and fixing
For some special purpose tool heads, such as drills or milling cutters, it is also necessary to weld and fix them. Common welding methods include brazing and solid phase additive manufacturing techniques. Although the cost of brazing is low, the connection strength is low; The solid phase additive manufacturing technology can provide higher connection strength and lower welding temperature.
7. Quality inspection and packaging
After the completion of all processing steps, the tool head needs to go through a strict quality inspection, including appearance inspection, size measurement, hardness testing, etc. Only qualified products are packaged and delivered for use.
8. Special craft
In some cases, the manufacturing of the tool head will also involve some special processes, such as electric discharge machining, laser cutting, etc., to meet specific needs.
Sum up
Carbide Cutter Teeth have a complex and sophisticated manufacturing process, involving powder metallurgy, machining, coating technology and other fields. Each step requires strict control to ensure high hardness, wear resistance and impact resistance of the tool head. This complex manufacturing process makes Carbide Cutter Teeth an indispensable and efficient cutting tool in modern industry.
