【 Summary Description 】 A good horse needs to be equipped with a good saddle, the use of excellent CNC machining equipment, if the use of the wrong tool is useless! Choosing suitable tool material has great influence on tool life, machining efficiency, machining quality and machining cost. This article provides the dry goods about the knowledge of cutting tools, it is recommended to collect learning.
A good horse needs to be equipped with a good saddle, the use of excellent CNC processing equipment, if the use of the wrong tool is useless! Choosing suitable tool material has great influence on tool life, machining efficiency, machining quality and machining cost. This article provides the dry goods about the knowledge of cutting tools, it is recommended to collect learning.
First, the tool material should have the basic performance
The choice of tool material has great influence on tool life, machining efficiency, machining quality and machining cost. Tool cutting to withstand high pressure, high temperature, friction, impact and vibration. Therefore, the tool material should have the following basic properties:
(1) Hardness and wear resistance. The hardness of the tool material must be higher than that of the workpiece material, generally required to be above 60HRC. The higher the hardness of the tool material, the better the wear resistance.
(2) Strength and toughness. Tool materials should have high strength and toughness, in order to withstand cutting force, impact and vibration, to prevent brittle fracture and blade breakage.
(3) Heat resistance. The tool material has good heat resistance, can withstand high cutting temperature, and has good oxidation resistance.
(4) Process performance and economy. Tool materials should have good forging, heat treatment and welding properties; Grinding performance, and the pursuit of high performance-price ratio.
Second, the type, performance, characteristics and application of tool materials
1. Diamond tool material
Diamond is an isomer of carbon. It is a hard material that has been found in nature. Diamond tools have high hardness, high wear resistance and high thermal conductivity, and are widely used in the processing of non-ferrous and non-metallic materials. Especially in the high-speed machining of aluminum and silicon aluminum alloy, diamond tool is the main cutting tool that is difficult to replace. Diamond tool which can realize high stability and long life is an indispensable tool in modern NC machining.
⑴ Types of diamond tools
① Natural diamond tool: Natural diamond as a cutting tool has a history of hundreds of years, natural single crystal diamond tool after fine grinding, cutting edge can be ground extremely sharp, cutting radius up to 0.002μm, can achieve ultra-thin cutting, can process high workpiece accuracy and very low surface roughness, is recognized, ideal and can not be replaced by ultra-precision machining tool.
② PCD diamond tool: Natural diamond is expensive, diamond is widely used in cutting or polycrystalline diamond (PCD), since the early 1970s, the use of high temperature and high pressure synthesis technology to prepare polycrystalline diamond (PCD blade, referred to as the successful development of polycrystalline diamond, In many cases, natural diamond tools have been replaced by synthetic polycrystalline diamond. PCD raw material source is rich, its price is only tens of one to one tenth of natural diamond. PCD cutting tool can not grind out extremely sharp edge, processing workpiece surface quality is not as good as natural diamond, now industry can not easily manufacture PCD blade with chip cutting groove. Therefore, PCD can only be used for non-ferrous and non-metallic fine cutting, it is difficult to achieve ultra-precision mirror cutting.
③ CVD diamond tools: Since the late 1970s to the early 1980s, CVD diamond technology appeared in Japan. CVD diamond refers to the synthesis of diamond film on heterogeneous matrix (such as hard alloy, ceramics, etc.) by chemical vapor deposition (CVD). CVD diamond has exactly the same structure and characteristics as natural diamond. The performance of CVD diamond is very close to that of natural diamond. It has the advantages of natural single crystal diamond and polycrystalline diamond (PCD), and overcomes their shortcomings to a certain extent.
