Case | Online Inspection in Automotive Manufacturing

Automotive production processes are complex, with on-site processes tightly linked. Processed parts from previous steps are continuously sent to subsequent steps for further processing. However, if these parts are not inspected in time, numerical deviations can accumulate in later processes, thereby increasing the product defect rate. Therefore, it is necessary to conduct online evaluations at key process nodes for parameters such as displacement, height, and flatness.

Grating micrometers can effectively solve these online inspection challenges for customers. The LG100/200 series is equipped with a photoelectric transmission-type linear scale, achieving resolutions of 1μm, 0.5μm, and 0.1μm. Paired with dedicated counters and interface devices, it enables real-time output of measurement data.

The LG100 series uses highly oil-resistant materials with a protection rating of IP67G, meeting the needs for integration into production sites. The LG200 series inherits the environmental resistance advantages of the LG100 series, with a smaller main body size, making it suitable for various flexible scenarios. The LGH series can achieve high resolutions of 0.005μm or 0.01μm over a wide range of 10mm, comparable to laser interferometers.
