Carbide Cutting Tool Has A High High Temperature Hardness And Wear Resistance
The working part of the Carbide Cutting Tool is to produce and deal with the chip part, including the blade, so that the chip broken or winding structure, chip removal or storage chip space, cutting fluid channel and other structural elements. Some of the working parts of the Carbide Cutting Tool are cutting parts, such as turning Carbide Cutting Tools, planers, boring Carbide Cutting Tools and milling cutters, etc .; some of the working part of the Carbide Cutting Tool contains cutting parts and calibration parts, such as drill, reaming drill, reamer, Knives and taps and so on. The role of the cutting part is to cut the chip with the blade, the role of the calibration part is to repair the machined surface and guide the cutting Carbide Cutting Carbide Cutting Tool.
The working part of the Carbide Cutting Tool has three kinds of integral, welded and mechanical clamping. The overall structure is made in the cutter body cutting edge; welding structure is the blade brazing to the steel body; mechanical clamping structure and two, one is the blade clamp on the knife body, the other Is a good brazing head on the cutter body. Carbide Cutting Tool is generally made of welded structure or mechanical clamping structure; porcelain Carbide Cutting Tool are used mechanical clamping structure.
In the choice of Carbide Cutting Tool angle, the need to consider the impact of a variety of factors, such as workpiece materials,Carbide Cutting Tool materials, processing properties (rough, finishing), etc., must be reasonably selected according to specific circumstances. Generally speaking, the angle of the Carbide Cutting Carbide Cutting Tool is the angle of the manufacturing and measurement. In the actual work, the angle of the actual work and the angle of the mark are different due to the different position of the Carbide Cutting Tool and the direction of the cutting movement. The material of the Carbide Cutting Tool must have high hardness and abrasion resistance, the necessary bending strength, impact toughness and chemical inertness, good process (cutting, forging and heat treatment, etc.) and is not easy to deform.
Usually when the material hardness is high, wear resistance is also high; bending strength is high, the impact toughness is also high. But the higher the hardness of the material, the lower the bending strength and impact toughness. High-speed steel because of its high bending strength and impact toughness, and good machinability, modern is still the most widely used Carbide Cutting Tool material, followed by carbide.
Carbide indexable inserts have now been coated with titanium carbide, titanium nitride, aluminum oxide or composite hard layers by chemical vapor deposition. The development of the physical vapor deposition method can be used not only for Carbide Cutting Tools but also for high speed steel Carbide Cutting Tools such as drill bits, hobs, tapes and milling cutters. Hard coating as a barrier to chemical diffusion and heat conduction barrier, so that the Carbide Cutting Tool in the cutting speed slowed down, the life of the coated blade and the coating compared to about 1 to 3 times higher.
Due to the high temperature, high pressure, high speed, and in corrosive fluid medium work parts, the application of more difficult to process materials, cutting the level of automation and processing accuracy requirements are getting higher and higher. In order to adapt to this situation, the direction of the development of the Carbide Cutting Tool will be the development and application of new Carbide Cutting Tool materials; further development of the Carbide Cutting Tool vapor deposition coating technology, high toughness in the high strength of the matrix deposited higher hardness coating, better solution Carbide Cutting Tool material hardness and strength of the contradictions; further development of indexable Carbide Cutting Tool structure; to improve the manufacturing accuracy of the Carbide Cutting Tool to reduce the difference in product quality, and to optimize the use of the Carbide Cutting Tool.
