In metal machining, selecting the right tool according to the characteristics of the workpiece to be processed can fully utilize the performance of the machine tool, improve production efficiency, and reduce production costs. Taking into account factors such as unit price, efficiency, longevity and shortened auxiliary time, it will be found that the high-cost, high-efficiency and long-life tools will reduce the overall production cost of a single product. The use of high-speed, high-efficiency machining centers has made metal machining a fast and efficient way, but whether it works, it depends on the choice of tools, because the tools are the most basic, effective and active for high-speed, high-efficiency cutting. the elements of. We have contacted the world's leading tool manufacturers, and studied various related materials such as average tool cost and production cost in developed countries. We found that reducing tool costs by 30% can reduce the cost per piece of production by 1%; increase tool life by 50%. Reduce production costs by 1%; while increasing processing efficiency by 20%, you can reduce production costs by 15%. This fully demonstrates that using modern cutting technology, selecting high-speed, high-efficiency tools, giving full play to the performance and efficiency of machine tools, and achieving high-speed, high-efficiency cutting is the right way to improve efficiency and reduce production costs in the production center of flexible production lines. Advanced tool characteristics The high-speed and high-efficiency tools used in the machining center should have the good hardness and wear resistance, high strength and toughness of the general tools, and should also have: 1. Higher reliability - stable cutting, consistent quality, less tool change and long life. 2. Higher installation accuracy and repeatability, good interchangeability and quick changeability. 3. Serialization, standardization and generalization, try to use machine clamps and multi-function composite tools. 4. Good chip breaking, chip and chip removal performance, ensuring that the chips do not wrap around the tool and the workpiece, and do not damage the machined surface, and do not hinder the casting of the cutting fluid. There are many types of tools available for high-speed, high-efficiency machining centers. The following tools are commonly used: 1. Ceramic tool has the characteristics of high hardness, good wear resistance, excellent heat resistance and chemical stability. It is not easy to bond with metal during processing. It is widely used in CNC machining. Among them, alumina-based ceramic cutter is suitable for carbon steel. Processing of alloy steel and cast iron materials; silicon nitride-based ceramic tools are more suitable for the processing of high-hard materials such as alloy cast iron and chilled cast iron, and the cutting speed can reach 500-1000m/min. 2. Polycrystalline diamond (PCD) tool processing aluminum and aluminum alloy materials have extremely high life and good precision, cutting speed can reach 1000 ~ 4000m / min, the cutting speed of high-speed milling aluminum alloy of Boeing Company has reached 5000 ~ 7500m / Min. Compared with PCD, CVD diamond tools have higher hardness, better wear resistance, smaller friction coefficient, stronger chemical stability and thermal stability, and life expectancy is 2 to 3 times longer than PCD. The disadvantage is that the toughness is not as good as PCD. CVD diamond tools are considered to be a new generation of tool materials for automotive engine product processing, especially for aluminum and aluminum alloy materials. 3. Cubic boron nitride (CBN) and polycrystalline cubic boron nitride (PCBN) tool materials have higher thermal stability and excellent chemical stability than PCD and VCD, in the environment of 1 200 ~ 1 300 ° C It does not react with iron-based materials; its hardness and wear resistance are close to that of diamond. It is very suitable for processing cast iron and hardened steel. The higher the hardness of the material to be processed, the better the performance of cubic boron nitride cutter. It has unparalleled superiority in machining precision, cutting efficiency, tool life and other aspects. Cubic boron nitride and polycrystalline cubic boron nitride tool materials are receiving more and more attention from all over the world. 4. Coated tools can be divided into CVD and PVD coated tools according to the coating method. According to the properties of the coating materials, they are divided into “hard†coated tools and “soft†coated tools, which can be divided according to the base material. Recently, nano-coated tools have been developed for carbide-coated tools, high-speed steel-coated tools, and ceramic and super-hard-coated tools. The coated tool has the flexibility to select the base material and coating material to achieve the desired performance, improve machining efficiency, improve machining accuracy, extend tool life and reduce machining costs.
