How to reduce scrap rate in machining

  First, confirm the drawing requirements confirmation, various processing requirements in the drawings, such as size requirements, behavioral tolerance requirements, roughness requirements, heat treatment requirements and so on. This information is very clear on the drawings, of course, in view of the design engineer's design ability, perhaps these requirements also have missed bids, at this time it is necessary for experienced mechanical process engineers to check. For example, for the drawings of the product, assembly and use of the product to do a certain degree of thinking, the design engineer missed the part to make up, in fact, is also a product continuous improvement process.

 Second, confirm the process content, the process flow of parts is an important basis for the implementation steps of our machining, but also an important guarantee for the quality of parts processing, in fact, the professional core ability of many mechanical process engineers is also reflected in this place. How to design the processing process of a part correctly, reasonably, low cost, high efficiency and high quality is the highest embodiment of the professional ability of a process engineer.

  To ensure the equipment capacity, the ability of processing equipment, in fact, the processing quality of a mechanical part, to a large extent, comes from the processing accuracy of the processing equipment. We usually call it "working machine" professionally, especially some high-precision parts processing, which is beyond the reach of manpower, and can only be completely handed over to the equipment to guarantee.

  Third, the correct processing method, the correct processing method selection, this point is actually mentioned in the previous equipment selection point, that is, the need to choose the correct processing mode according to the processing capacity and processing method of the equipment. Therefore, in the choice of hardware processing methods, we need to consider a lot of surfaces, which can roughly start from these aspects "processing accuracy, processing quality, processing cost, processing efficiency, enterprise equipment resources" and so on.

  Finally, for the current utilitarian society, we actually have a very great difficulty in regulating the working attitude of workers, and many seemingly unreasonable quality accidents, after a defense become so reasonable, which is really unexpected, so it is very necessary for enterprises to carry out appropriate professional ethics education and professional quality training for employees, and there needs to be a balance between quality and interests, this balance can not simply be handed over to the conscience of workers, but should resort to systems and norms.
