We know that Dongguan CNC Precision Processing Factory has high precision requirements for non-standard parts. Precision machining has good rigidity, high production accuracy, accurate tool setting, and can process parts with high precision requirements.
Precision parts processing cannot complete all surface processing tasks at once. The entire machining process of precision parts can be divided into the following stages:
(1) Rough machining stage. Most of the machining allowance on each machined surface is removed and a precise benchmark is processed, with the first consideration being to maximize productivity.
(2) Semi precision machining stage. Remove any defects that may occur after rough machining, prepare for surface finishing, and achieve a certain machining accuracy to ensure appropriate finishing allowance, while completing unnecessary surface processing.
(3) Precision processing stage. At this stage, choose a high cutting speed, small feed rate, and cutting depth to remove the finishing allowance left by the previous process and ensure that the surface of the part meets the technical requirements of the pattern.
(4) Finishing stage. Mainly used to reduce surface roughness values or strengthen machined surfaces, mainly for high surface roughness requirements (ra ≤ 0.32 μ m) Surface processing.
(5) Ultra precision machining stage. Processing 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 include: precision cutting, precision mirror grinding, and precision grinding and polishing.
