The quality of precision automotive components affects the performance of the entire vehicle. This stage is made of durable aluminum alloy and can adapt to the environment of testing workshops. Driven by a micrometer, it has high adjustment precision; the 360° rotation function enables comprehensive testing of the surface precision of components, while the ±5° fine adjustment allows for accurate detection of details such as component gaps and angles. It helps technicians control the quality of precision automotive components, thereby improving the safety performance and service life of automobiles.
