III. Application Scenarios of PCD Cutting Tools
The application scenarios of PCD cutting tools are completely based on their performance advantages, focusing on difficult-to-machine materials and high-precision machining needs. According to machining materials and working conditions, they can be divided into the following 4 categories, all with corresponding technical images:
1. Machining of Non-ferrous Metals and Alloys
Suitable for turning, milling and drilling of non-ferrous metals such as aluminum, copper, magnesium, zinc and their alloys, especially for mass and high-precision machining scenarios. The surface finish of machining can reach Ra0.02-0.1μm, the machining efficiency is 5-20 times higher than that of traditional tools, and there is no adhesion or damage.
2. Machining of Composite Materials
For difficult-to-machine materials such as Carbon Fiber Reinforced Polymer (CFRP) and glass fiber composite materials, PCD cutting tools can effectively solve problems such as fiber tearing, delamination and burrs, realize efficient and precision cutting, and the surface of the processed workpiece is free of damage without subsequent polishing.
3. Ultra-precision Machining
Used for ultra-precision machining of semiconductors, optical components, precision instrument parts, etc. The edge precision reaches the nanometer level, which can process SiC/GaN wafers, optical free-form surfaces, etc. The surface roughness of machining is Ra≤0.01μm, which meets the precision requirements of high-end manufacturing.
4. Machining of High-hardness Materials
Suitable for machining high-hardness steels, cemented carbides, ceramics and other materials above HRC60, it can realize high-speed cutting, avoid the problems of rapid wear and low machining efficiency of traditional tools, and is especially suitable for complex working conditions such as intermittent cutting and heavy-load cutting.
