High-speed cutting technology for automotive stamping dies is of great benefit to save production time and improve production efficiency, but generally high-speed cutting requires milling speed greater than 40,000 revolutions per minute. All parts of the high speed lathe must be matched to make the machine work properly. What are the specific requirements for automobile stamping die production?
Because the high-speed cutting lathe is controlled by microcomputer program, it is necessary to have a central processing unit (CPU) and large-capacity storage equipment which can process large amounts of data quickly; have a faster data transmission capacity and network transmission capacity; have error compensation functions, including measurement error compensation, quadrant error compensation, thermal error compensation.
The drive system requires a large feed speed and acceleration, generally 20-30 meters per minute and 20-40 meters per second square.
Main shaft of high-speed airport. Because the stamping die in high-speed cutting to milling speed is very fast, so the speed of the spindle should also keep up with the general need to adjust between 10,000 to 100,000 per minute, with rapid speed-up and rapid precision stop performance. Therefore, the bearing structure of lathe generally adopts hydrostatic pressure, aerostatic and suspension magnetic levitation.
The machining of automobile stamping dies is carried out by milling cutters. Milling with tens of thousands of rotations tests the hardness and wear resistance of the cutters. Therefore, for cutting tool materials, cemented carbide and polycrystalline diamond must be used. At the same time, tool positioning must be precise and error controlled within 0.001mm.

Automotive stamping parts refer to parts processed by stamping technology during the production of auto parts. Their quality is crucial to the safety and reliability of the entire vehicle. In order to ensure that the quality of automotive stamping parts meets the requirements, a series of quality inspection standards have been formulated. The following are some common requirements for automotive stamping parts quality inspection standards.
1. Appearance quality
The appearance quality of automotive stamping parts is a very intuitive inspection item, which mainly includes the surface finish, concave and convex, scratches, oxidation and rust of the parts. The standard of appearance quality is usually agreed upon by the Brands and the customer, and samples or pictures are generally used as the standard, with specific descriptions of allowable defects.
2. Dimensional accuracy
Automotive stamping parts require high dimensional accuracy, and measuring tools are usually used for measurement. Common dimensional accuracy standards include tolerance range, average deviation, absolute value of deviation and ratio of absolute value of deviation, etc. The dimensional accuracy standards of different parts will vary according to actual usage and technical requirements.
3. Material quality
The material quality of automotive stamping parts is an important factor in ensuring their performance. The testing of material quality includes material type, chemical composition, physical properties and heat treatment. Common detection methods include spectral analysis, tensile testing, hardness testing and metallographic analysis.
4. Durability
Automotive stamping parts need to withstand long-term reciprocating motion and loading, so durability is one of its key indicators. Durability testing usually uses a test bench to conduct simulation tests to evaluate the service life and failure probability of parts under actual use conditions.
5. Welding quality
For some automotive stamping parts, welding is one of the processes necessary to complete their assembly. The detection of welding quality mainly includes the shape of the weld, the welding strength and the fusion of the welding materials. The standard of welding quality is usually determined based on the welding process regulations and relevant welding standards.
6. Surface treatment quality
In order to protect the surface of automotive stamping parts from corrosion and damage and improve its decorative effect, surface treatments such as galvanizing, spraying and coating are usually required. The detection of surface treatment quality mainly includes indicators such as film thickness, adhesion and anti-corrosion performance.
7. Precision
Some automotive stamping parts require high precision to ensure the accuracy of their fit and movement. Precision testing is usually performed using a three-dimensional coordinate measuring instrument or special testing equipment to evaluate the accuracy of parts such as size and shape.
8. Performance testing
Corresponding performance tests are required according to different types of stamping parts. For example, stamped parts for automobile chassis need to pass performance tests such as dynamic strength and stiffness, while automobile exterior parts pay more attention to corrosion resistance and wear resistance.
9. Environmental adaptability
Automotive stamping parts need to have certain environmental adaptability, that is, they can still work normally and maintain a certain service life under different climate conditions and working environments. Common environmental adaptability test items include high temperature test, low temperature test, damp heat test and salt spray test.
The above are some common quality inspection standards for automotive stamping parts. The specific requirements will vary according to the type of parts, use and relevant technical standards. In order to ensure the quality of automotive stamping parts, Brandss need to strictly conduct quality inspections in accordance with relevant standards to ensure that the products are qualified and meet the requirements, so as to achieve the goal of improving the quality and safety of the entire vehicle.
