Dalian precision machining for precision instruments used for measurement, its structure can be divided into eight functional parts: reference, feeling conversion, conversion, amplification and transmission, aiming / reading, data processing, display and recording, drive control, mechanical structure and so on. Flow detection precision instruments, such as various barometers, vacuum meters, multi wavelength temperature measuring instruments, flow meters and altimeters.

The skills of operators, which involves the operating skills of operators of various equipment. These skills include in-depth understanding of equipment, understanding of machining, understanding of processed parts and materials, etc. these skills can be slowly accumulated in ordinary work. The key to the skills of operators is practice and theory.

Modern enterprises use the principles and methods of system engineering to organize and guide production, and regard the production process as a production system with input and output. When receiving the materials entrusted for processing, register the memo book according to the contract price (or do not record the actual amount), debit "entrusted processing materials - a company" (indicate the material quantity), and make corresponding notes when receiving.
