Common Sense of Diamond Metal Cutter You Should Know

Ⅰ. Natural diamond metal cutter characteristics


Natural diamond is a great material for creating cutting tools for non-ferrous metals and non-metallic materials because of its high hardness, wear resilience, low coefficient of friction, and superior thermal conductivity.


At the end of the 1950s, natural single crystal diamond metal cutters were used to cut precision and ultra-precise items. It was further refined to necessitate the manufacturing of aspheric curved mirrors, followed by huge mirrors. It is necessary to have a high level of form accuracy and a low level of surface roughness.


At this time, the use of natural single crystal diamond metal cutters is quite mature, but due to their low production and high cost, coupled with the emergence of man-made diamonds, the use of natural single crystal diamond metal cutters in the field of precision machining is waning. Several artificial diamonds, with their good performance to price ratio and gradually mature use of technology, have gradually occupied the relatively low requirements.


Ⅱ. The application of a diamond metal cutter


Diamond metal cutter's high performance determines its wide applicability in processing.


1. Diamond metal cutter for non-ferrous metals that are difficult to machine


Copper, zinc, aluminum, and other non-ferrous metals and alloys stick to the tool during processing and are therefore unsuitable for processing. The use of diamond metal cutters has a low coefficient of friction, and non-ferrous metal affinity and diamond metal cutters can prevent metal and tool bonding.


Because diamond has a high modulus of elasticity, the edge distortion is minor when cutting non-ferrous metals, and the extrusion deformation is small when cutting non-ferrous metals, so the cutting process is completed with little deformation, which improves cutting surface quality.


2. Diamond metal cutter for processing non-metallic materials that are difficult to machine


When processing difficult-to-machine non-metallic materials with a large number of high hardness masses, such as glass fiber reinforced plastics, silicon filled materials, and hard carbon fiber/epoxy resin composites, the hard masses of the materials cause the diamond metal cutter to wear out quickly and are difficult to process with carbide tools, whereas the diamond metal cutter has a high hardness and good wear resistance, resulting in high processing efficiency.


3. With the development of current integrated technology, ultra-precision cutting of diamond metal cutter is emerging


Machine processing in the direction of high precision development has placed considerable demands on the tool's performance. Because diamond has a low friction coefficient, a low coefficient of thermal expansion, and a high thermal conductivity, it can cut down very thin chips, allowing them to flow out easily. It also has a low affinity for other materials, making it difficult to produce chip tumors. It also has a low heat generation coefficient, allowing it to avoid heat on the diamond metal cutter blade and workpiece, making it less likely to blunt.
