Description of material performance accuracy for automobile metal parts processing

2024-12-27

Hardness: different automotive metal parts need to have appropriate hardness according to their use requirements. For example, after quenching and other heat treatment processes, the surface hardness of automobile gears is generally required to reach HRC58-62, while the core hardness is controlled between hrc30-40, which can not only ensure the wear resistance of gears, but also make them have good toughness and prevent gear fracture.

Strength and toughness: the key stressed parts of the vehicle, such as the frame and parts of the suspension system, need to have high strength and toughness. Taking the high-strength bolt as an example, its tensile strength is generally required to be more than 1000MPa, and it also needs to have a certain impact toughness, so as to ensure that it can bear complex loads without fracture during vehicle driving.

Shape accuracy detection

In addition to dimensional accuracy, the shape accuracy of the parts cannot be ignored. Detect shape errors such as roundness, cylindricity, and flatness of parts using equipment such as roundness meters and contour meters. For example, when processing high-precision bearing rings, the accuracy of roundness and cylindricity directly affects the rotational accuracy and service life of the bearing.

Dimensional accuracy testing

Using advanced measuring tools and techniques, such as coordinate measuring instruments, optical imagers, etc., to accurately measure the dimensions of parts. For precision parts, dimensional tolerances are usually controlled at the micrometer level, so high-precision measuring equipment is required to ensure the accuracy of the test results. For example, when processing precision molds for mobile phone chi...
