Technical indicators are specific data used to reflect the performance and function of precision instruments. They are not only the basic basis for designing precision instruments, but also an important basis for inspecting the quality of finished products. Technical indicators are related to the purpose, function, characteristics, etc. of the instrument, and different types of instruments and equipment have different technical indicators. Technical indicators can be summarized into the following aspects.

(1) Reflect the performance of design work

Specifically, it refers to various functions of instruments and equipment, such as processing range, motion range, speed range, measurement range, display function, printing data function, etc.

(2) Reflecting the accuracy of instruments and equipment

For example, machining accuracy, surface roughness, manufacturing accuracy, engraving accuracy, measurement accuracy, indication error, resolution, sensitivity, etc.

(3) Reflecting the degree of automation of instruments and equipment

For example, numerical control, microcomputer control, fully automatic, semi-automatic, computer automatic processing, etc.

(4) Reflecting the efficiency of instruments and equipment

For example, productivity, inspection rate, etc.
