The machining accuracy of high-precision parts is more important

At present, there are many orders from both ordinary parts processing plants and Dalian precision casting processing plants. It is precisely because of so many reasons that many customers will make a comparison when looking for processing plants, and then place orders according to the conclusions. Now, the requirements of customers for parts processing are no longer public and simple processing, but need a high-precision product precision to meet the use effect.

For precision parts processing, there are strict requirements on the size, such as the diameter of the cylinder. Only qualified parts with positive and negative errors within the specified requirements, otherwise they are unqualified parts;

There are also specific and strict requirements for length, width and height, and there are also provisions for positive and negative errors. For example, if the diameter of an embedded cylinder (take simple basic components as an example) is too large and exceeds the allowable range of errors, it will result in failure to insert. If the actual diameter is too small and exceeds the lower limit of allowable negative values of errors, it will result in too loose and unstable insertion.

These are unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable range of error. All these are unqualified products, which will be scrapped or reprocessed, which will inevitably lead to increased costs.

The processing of precision parts is not simple, and the process is complex, so you should not be careless in selecting manufacturers. Although it is normal to compare, if you order large quantities of products, if someone gives you a lower processing price, but if you choose some materials that do not meet the requirements in product processing, you will have to add a part of the processing fee to the original cost, which will also delay the delivery, It is not worth the loss.
