The manufacturers of precision measuring instruments have summarized some relevant characteristics of precision measuring instruments to us. 1. There are many measurement items, such as length, shape and position error. Especially for the measurement that is difficult to solve with some mechanical measuring instruments and measuring instruments, such as: deep hole inner diameter, small hole inner diameter, narrow groove width, etc., compare with pneumatic measurement Completed briefly. 2. The magnification of the measuring instrument is high, and the human error is small, which will not affect the measurement accuracy; there is no mechanical friction during operation, so there is no return error. 3. The operation method is simple, the reading is simple, you can make successive measurements, and it is very simple to see whether each size is qualified. 4. The measurement head is not directly touched with the surface to be measured, reducing the influence of the measurement force on the measurement results, and at the same time preventing the surface of the measured piece from being scratched. It is especially applicable to the measurement of thin-walled parts and soft metal parts. 5. Due to non-touch measurement, the measuring head can reduce wear and prolong the use period. The hose connection between the main body of the pneumatic measuring instrument and the measuring head can be used to complete the long-distance measurement. 6. The structure is simple, the operation is reliable, and the adjustment, operation and maintenance are very convenient.
