Product Description

CNC machining metal parts


CNC machining metal parts

 

CNC precision parts processing

When the machining accuracy reaches or exceeds 0.1 μ m, it is called ultra precision part machining. In aerospace industry, It’s mainly used to process precision mechanical parts in aircraft control equipment, such as precision mating parts in hydraulic flattening and dynamic servo, frame and shell of gyroscope, air flotation, liquid floating bearing components and floats, etc. The structure of aircraft precision parts is complex, the rigidity is small, the precision is very high, and the proportion of difficult to process raw materials is large. 


The technological efficiency of CNC machining metal parts is as follows: 

① the geometric form and mutual position accuracy of parts reach micron or angular second level; 

② the boundary or characteristic dimension of parts are under micron level; 

③ the surface micro unevenness (surface unevenness and height difference) of parts is less than 0.1? Micron; 

④ the mutual parts can meet the requirements of coordination;

 ⑤ some parts can meet the accurate mechanical or other physical characteristics For example, the stiffness of the torsion bar of the float gyroscope and the stiffness coefficient of the flexible element.

 

In recent years, most of the automobile, mold parts and metal processing are made with CNC machining metal parts center, and most of the hole processing is made with advanced equipment such as machining center and CNC machine tool. High-speed and high-precision drilling processing has been put on the agenda.
