overview

Diamond tool has the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, which can obtain high machining accuracy and processing efficiency in high-speed cutting. The above characteristics of the diamond tool are determined by the crystal state of the diamond. In diamond crystals, the four valence electrons of carbon atoms are bonded by tetrahedral structure, and each carbon atom forms a covalent bond with four adjacent atoms, thus forming a diamond structure, which has a strong binding force and directivity, so that diamond has extremely high hardness. Because the structure of polycrystalline diamond (PCD) is a fine crystalline diamond sintered body with different orientation, the hardness and wear resistance of PCD are still lower than that of single crystalline diamond although the binder is added. However, because the PCD sintered body is isotropic, it is not easy to crack along a single cleavage plane.
Diamond "PCD" is specialized in the finishing of copper, aluminum alloy, cemented carbide, graphite, ceramics and high hard wear-resistant materials. It has the characteristics of long service life, high production efficiency, high surface finish and high processing precision. Higher processing efficiency and lower cost than carbide and natural diamond tools, widely used in automobiles, diesel engines, motorcycles, aerospace, home appliances, instruments and precision machinery and other industries.

Judging method of tool wear:
1. Look at the processing process: if the processing process, continuous regular sparks, indicating that the tool has been worn, according to the average life of the tool
Change knives in time.
2. Look at the color of the iron filings: the color of the iron filings changes, indicating that the processing temperature has changed, and this time the tool has begun to wear.
3 Look at the shape of the iron filings: zigzag on both sides of the iron, abnormal curling of the iron filings, and the iron filings become finer, which are all tools
The judgment basis of damage.
4. Look at the surface brightness change of the workpiece: the brightness continuously reduces the tool has been worn.
5 Processing vibration sound changes: tool wear will cut the resistance is too large, pay attention to avoid "knife", resulting in workpiece scrap
6. Observe the change of machine load data: If there is a significant incremental change, it indicates that the tool has been worn.
7. Observe the burr change on the edge of the workpiece: when the tool is cut out, the workpiece has a serious burr and the phase roughness decreases.
8. Observe the size change of the workpiece: obvious phenomena such as the size change of the workpiece are also the criteria for tool wear.
9. Tool life table (based on the number of processed workpieces): some high-end equipment manufacturing or single product mass production enterprises use it to guide production, this method is suitable for processing expensive aerospace, steam turbines, automotive key components such as engines and other production enterprises.

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 and other effects. 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, and it is generally required to be above 60HRC. The higher the hardness of the tool material, the better the wear resistance.
(2) Strength and toughness. The tool material should have high strength and toughness in order to withstand the cutting force, impact and vibration, to prevent the brittle fracture and blade collapse of the tool.
(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 material should have good forging performance, heat treatment performance, welding performance; Grinding processing performance, and the pursuit of high performance-price ratio.
