At present, there are only about 300 gear production plants in the national gear industry with metering rooms that are basically equipped with Instruments. There are more than 200 coordinate measuring instruments in total, and most of them are imported from abroad; all kinds of (mechanical, photoelectric, numerical control) gear measuring instruments 1000 Yutai, including more than 30 gear measuring centers, about 10 sets of test instruments and worm gear checkers, no more than 50 sets of gearbox test benches and transaxle test stands; roundness meters, length measuring instruments, optical indexing More than 500 measuring instruments such as head, roughness meter, projector, and Wangong display. The remaining 200 gear manufacturers have almost no precision measuring instruments, and some companies do not have a measuring instrument other than the 10,000 energy devices.
Experts pointed out that in order to further improve the quality and competitiveness of the gear industry, the corresponding types of precision testing instruments should be equipped as soon as possible. In the next few years, large and medium-sized gear companies should be equipped with coordinate measuring machines, gear measuring centers and other precision measuring instruments and complete central measuring rooms. Small enterprises should also be equipped with necessary precision measuring instruments.
