Description

[0002] Mechanical engineering assembly refers to the connection of mechanical parts or components in accordance with the technical requirements of the design, and the combination of mechanical parts or components into machines. Mechanical assembly is an important part of machine manufacturing and repair, especially for mechanical repair. Since providing assembly parts is beneficial to the situation during mechanical manufacturing, the assembly work is more special. The quality of assembly work plays a very important role in the efficiency of the machine, the repair period, the labor and cost of the work.
