精密机械零部件加工一般都是针对精密机械设备的零部件进行加工生产，这就要求达到的精度非常高，因此我们除了要了解精密机械零部件加工对材料的具体要求以及精密机械零部件加工的常用技巧，还应当要了解精密机械零部件加工的加工过程都有哪些步骤，下面J9.com加工跟大家分享一下精密机械零部件加工的5个阶段。

1.粗加工

主要考虑的是提高生产率。各个加工面大部分加工余量被切除，且加工出精基准。

2.半精加工

主要是切除粗加工后可能产生的缺陷，同时完成次要表面的加工。须达到一定的加工精度以便为精加工阶段做准备，保证适当的精加工余量。

3.精加工

在精加工阶段主要采用大的切削速度、小的进给量和切削深度切除半精加工留下的加工余量，使精密机械零部件表面满足图纸的技术要求。

4.光整加工

主要用于降低表面粗糙度或强化加工表面，主要用于表面粗糙度要求很高的表面加工。

5.超精密加工

主要是用精密切削、精镜面磨削、精密研磨和抛光等加工方法使工件的加工精度在0.1-0.01μm，表面粗糙度值ra≤0.001μm。

总结

精密机械零部件加工的5个阶段是由粗到细，逐步加精的过程，经过这5个阶段的加工，机械零部件的精度就能达到客户所需的要求。J9.com专注于精密机械零部件加工与制造，可以根据客户需求来图来料加工，制造出客户满意的精密机械零部件。

Precision machinery parts processing is generally precision machinery parts and components for processing production, which requires to achieve precision is very high, so we in addition to understand the specific requirements of the precision machinery parts processing on the material and the skills of precision machinery parts processing, should also be to understand the precision machinery parts processing process, what are the steps, the following los work processing and share with you the five stages of precision machinery parts processing.

1. The rough machining

The main concern is to increase productivity. Most of the machining allowance of each machining surface is removed and processed to the precision standard.

2. Semi-finishing

It is mainly to remove the possible defects after rough machining and finish the processing of secondary surface at the same time. A certain precision must be achieved in order to prepare for the finishing stage and ensure the proper finishing allowance.

3. The finishing

In the finishing stage, large cutting speed, small feed and cutting depth are mainly used to cut the machining margin left by semi-finishing, so that the surface of precision machinery parts can meet the technical requirements of the drawing.

4. Finishing

It is mainly used to reduce the surface roughness or strengthen the processed surface.

5. Ultra-precision machining

It is mainly used for precision cutting, fine mirror grinding, precision grinding and polishing to make the workpiece processing accuracy in 0.1-0.01 microns, surface roughness ra≤0.001 microns.

conclusion

The five stages of precision mechanical parts processing are from coarse to fine, and gradually refined. After the five stages of processing, the precision of mechanical parts can meet the requirements of customers. Luogong focuses on precision machinery parts processing and manufacturing, can according to customer demand to process, produce customer satisfaction precision machinery parts.
