Cemented carbide rod and the name of cemented Carbide bar, is a hard alloy (WC) as the main raw materials, coupled with other precious metals and paste by the use of powder metallurgy method to suppress sintering of high hardness, high-strength alloys, widely used in national production and processing fields, Carbide Round Bar such as tungsten carbide drill bit.
Characteristics of cemented carbide round rods
1. High quality superfine tungsten carbide and imported cobalt powder as raw material.
2, the use of the world's advanced low pressure sintering technology to standardize production.
3. High strength and hardness.
4, with excellent red hard, good wear resistance, high modulus of elasticity, high flexural strength, good chemical stability (acid, alkali, high-temperature oxidation), good impact toughness, Carbide Round Bar low expansion coefficient, heat conduction, conductivity and iron and its alloy similar characteristics.
5, high-tech advanced precision Equipment: Germany imports 10MPa low pressure sintering furnace sintering.
6, a unique new process: vacuum high temperature and high pressure sintering. Products in the final stage of the use of pressure sintering, greatly reduce porosity, improve compactness, greatly improve the mechanical properties of products.
7, Product characteristics: Many materials, Carbide Round Bar can be used for different uses of the demand, complete specifications, blank size precision (reduce processing volume, improve production efficiency).
1, the use of low pressure sintering technology, stable and reliable quality;
2, the use of overpressure automatic pressure relief extrusion equipment, all types of specifications of cemented carbide solid fine grinding rod can be produced: the use of German imports of automatic extrusion equipment, can be adjusted according to different requirements, Carbide Round Bar is conducive to the production of different models of bar.
3. High precision grinding of the bar, can reach the mirror effect: the use of CNC grinder, with the maximum polishing rate, can quickly remove the damage layer produced during polishing, improve surface finish, up to the maximum mirror effect. Precision Grinding rod Material: diameter tolerance d≤±0.01 Length tolerance l≤±0.5.
Carbide rods have good abrasion resistance and flexural strength, can be used to make a variety of drill bits, automotive special knives, printed circuit board special knives, engine-specific knives, Carbide Round Bar watches and clocks processing tools, the overall vertical milling cutter, the overall reamer, carving knives and so on, but also can make carbide punch, Mandrel, Top and piercing tools-perennial supply standard specification round bar blanks and various fine grinding rods
