With the rapid development of China's automobile industry, the output and quality of automobiles are constantly improving. Machining and metal cutting related to the manufacture of engines, gearboxes, transmission shafts, axles and other components required for automobile manufacturing, especially automobiles. The workload has soared, the demand for tools that are closely related to machining and metal cutting is on the rise, and the variety of changes in the structure and materials of the engine and components puts higher demands on the geometry and material of the relevant tools. Comprehensive automotive industry requirements for tools, automotive tools must be efficient, high quality, high stability and special features 1, high efficiency – Host production line pursues high efficiency and production beat balance – On limited equipment, the tool is often required to use the maximum possible machining parameters for high efficiency and cycle balance. – often sacrifices tool life to meet beat requirements, but at the same time guarantees minimum tool life – Extend tool life only if it is within the range allowed by the beat – In order to minimize the auxiliary time, a large number of composite tools and special tools are used. 2, high stability – Automotive production requires extremely high reproducibility and repeatability. – Require high-quality tool quality for long-term delivery, such as achieving the same tool life and dimensional deviation. – The critical dimension consistency requirements of automotive companies are high, which also requires a high degree of identity between different batches of tools. 3, high quality – The automotive industry has high processing requirements (up to μm), and quality is the first indicator for automotive companies' tool procurement. – High quality tools can result in significant reductions in production costs – High quality tools also reduce tooling costs for powertrains 4, specialization – high efficiency, improved processing efficiency and increased productivity – Improve processing quality – High stability, high processing stability and high reliability – low cost, in line with the principle of “lean production†– maximizing economic benefits with minimum investment With the continuous development of the automotive industry, new requirements have been put forward for automotive knives . From a technical point of view, there are mainly the following trends: 1. Heavy load: higher metal removal rate greatly improves processing efficiency; 2, compound: lower cost, in line with the "lean production" principle - to maximize economic benefits with minimum investment; 3. Specialization: Specially designed tools meet the requirements of production efficiency and cost; 4. Standardization: Standard blade and accessory designs are easier to manage; 5, high speed: by increasing the cutting speed to meet the needs of production tempo acceleration; 6. Variety: No tool company can provide all the tools needed by the automotive industry. There are no best tools, only the most suitable tools.
