The arrangement of such a machining process is still mainly customized for machining high precision parts.

First of all, a few words about its main role.

The main role of semi-finishing machining is twofold.

The first is to avoid the roughing allowance is too large, resulting in a large number of processing stresses gathered, thus causing excessive stress deformation of the part in the finishing regret.

The second is to lengthen the production cycle of the parts, in reducing the processing stress at the same time, to further allow the parts to have a certain natural aging time, can be in the finishing process before making a certain degree of release of processing stress, so as to ensure the machining accuracy of the parts.

Of course, the preparation of such a processing process is now appropriate, which also needs to be discerning to look at this matter.

In fact, modern processing technology and material technology has changed a lot.

For example, CNC machining can well ensure the balance between the size of the machining allowance and the speed of processing, can fully use the high-speed characteristics of the machine tool to achieve a small amount of tool, high feed fast processing mode, which can be a good solution to the problem of machining stress.

And now the tool technology has also been very much improved, the same processing mode, choose a better tool to ensure better processing efficiency and quality, but also to make the processing stress less, which for the modern processing tool is completely have the opportunity to do.

In addition, materials technology has also been developed rapidly, many materials in the processing of stress aggregation and release characteristics are much better, and many stress relief means have become more effective and convenient, so for the traditional "semi-finishing" production mode has the significance of retaining, depending on the different processing environment, different Processing requirements to customize their own, there is no need to set in stone to follow such rules.

For example, CNC processing, CNC technology is now very powerful, often a one-time clamping can meet the processing of many processes, we can not set a "semi-finishing" because of the processing process really have to process half of the parts to dismantle, and then wait a few days to process, which is obviously unrealistic, and processing accuracy may also be compromised. This is obviously unrealistic, and the machining accuracy may be compromised, so we use more high-speed small margin machining mode, so that the parts in the process to avoid machining stress, so as to ensure the processing of parts.

For the traditional machining process, it has a very good reference value, but it also has the limitations of the times and helplessness, with the development of science and technology, what we have to do is to combine modern technology, based on the traditional experience accumulated and technical knowledge to better serve the quality of processing, holding the residual may not make a big mistake, but it must not be the choice to maximize the benefits, completely abandon the traditional experience certainly has the courage, but It is not necessarily the most correct path.
