Operating flow and process characteristics of precision parts processing

In recent years, with the rapid development of China's precision parts processing industry , people have put forward higher requirements for the operational process and process characteristics of the industry.

Let’s first look at the following operating procedures for precision parts processing:

1. Advanced benchmark. That is, the reference surface is first processed. During the processing process, the surface of the part used as the positioning reference should be processed first so that it can provide a precise reference for the processing of subsequent processes as soon as possible.

Distinguish between different processing stages. High-quality mechanical surfaces are required to distinguish between the processing stages and can generally be divided into three stages: rough processing, semi-finishing and finishing. First of all, we must ensure the quality of processing, which is conducive to the scientific use of equipment, facilitate the arrangement of heat treatment processes, and easily detect blank defects.

3. Face first and then hole. Box, rack, rod and other parts should be processed first and then holes. This enables the hole to be positioned and processed, ensuring the position accuracy of the plane and holes, and also bringing convenience to the processing of plane holes.

4. Light finishing treatment. In the final stage of the process road, the primary surface is polished, such as grinding, honing, fine grinding, rolling, etc. The formulation of the fine parts processing process route can be roughly divided into two links: formulating the fine parts processing process regulations; during the processing process, firstly, formulating the process route for parts processing, then determining the process scale, equipment and process configuration used, and cutting. Regulations, working hours quotas, etc.

Those who are proficient in operating precision parts processing processes have good general processing technology characteristics. Good process characteristics will naturally add a lot of color to the product. Good process characteristics can make the product more perfect or better, and precision parts processing is one of them.

Discussion on the characteristics of precision parts processing technology

Stamping tensile molds can be processed into parts of various sizes and shapes, such as stopwatches of clocks, to automotive longitudinal beams, coverings, etc., plus the cold deformation and strengthening effect of the material during stamping, the stamping High strength and stiffness.

2. Since the size and shape accuracy of the stamping mold during the stamping process is guaranteed, it will generally not damage the surface quality of the stamping parts, and the service life of the mold is generally long, the stamping quality is stable, the interchangeability is good, and it has 'Exactly the same' characteristics.

3. The stamping process generally does not produce chips, the material consumption is less, and no other heating equipment is required. Therefore, it is a material-saving and energy-saving processing method, and the stamping parts are costly.

4. The production efficiency of stamping tensile mold processing is high, and it is easy to operate, making it easy to achieve mechanization and automation. This is because stamping is completed by dies and stamping equipment. The stroke of ordinary presses can reach dozens of times per minute, and high-speed pressure. It can reach hundreds or even more than a thousand times per minute, and it is possible to obtain a punch every minute stamping stroke.

The above-mentioned operating procedures and process characteristics of precision parts processing can make parts have many advantages. Therefore, this is a good process characteristic, which can make our production efficiency high, operate particularly conveniently, and have a long service life.
