Processing procedure of non-standard parts in cnc precision processing plant
We know that Dongguan CNC precision processing plant has high requirements for the accuracy of non-standard parts. Precision machining has good rigidity, high production precision, accurate tool setting, and can process parts with high precision requirements.
Precision parts cannot be processed at one time to complete all the processing contents of all surfaces. The whole processing process of precision parts can be divided into the following stages:
(1) Rough machining stage. Most of the machining allowance of each machined surface is removed, and an accurate benchmark is machined. The first consideration is to maximize the productivity.
(2) Semi finishing stage. Remove the defects that may appear after rough machining, prepare for the finish machining of the surface. It is required to achieve a certain machining accuracy, ensure the appropriate finish machining allowance, and complete the processing of unnecessary surfaces.
(3) Finishing stage. At this stage, large cutting speed, small feed rate and cutting depth are selected to remove the finishing allowance left by the previous process and make the part surface meet the technical requirements of the pattern.
(4) Finishing stage. It is mainly used to reduce the surface roughness value or strengthen the machined surface. It is mainly used for high surface roughness requirements (ra ≤ 0.32 μ m) Surface finish.
(5) Ultra precision machining stage. Machining accuracy is 0.1-0.01 μ m. Surface roughness value ra ≤ 0.001 μ M is in the processing stage. The main processing methods of Dongguan CNC Precision Processing Factory are: precision cutting, precision mirror grinding, precision grinding and polishing.
