With the development of new energy vehicles and lightweight trends, the demand for cutting tools in the automotive industry has undergone significant changes:
The usage of aluminum alloy has surged - the market demand for PCD cutting tools and diamond coated cutting tools continues to expand. PCD cutting tools can have a lifespan tens of times longer than conventional hard alloy cutting tools in aluminum alloy processing, making them an ideal choice for large-scale production.
The increasing application of high-strength steel and hot formed steel in white car bodies has raised higher requirements for the anti collapse and heat resistance of cutting tools. Multilayer nano coated hard alloy cutting tools and ceramic cutting tools have broad application prospects in this field.
**The use of carbon fiber reinforced polymer (CFRP) in sports cars and high-end models is becoming increasingly popular. The interlayer structure of composite materials can lead to delamination and burrs during processing. It is recommended to use CVD diamond coated tools with sharp edges and special geometric angles, combined with high-pressure cutting fluid to reduce machining damage.
