For precision China mechanical parts, the processing […]
For precision China mechanical parts, the processing is very strict, and the processing procedures include unfeed and outflied. There are specific requirements for size and accuracy, such as 1mm plus or minus micrometers. If the size is too large, it will become a waste product. At this time, it is equivalent to reprocessing, which takes time and effort, and sometimes even makes the entire processing material scrap. This caused an increase in cost, and at the same time, the parts were definitely unusable.
For precision parts processing, there are mainly dimensional requirements, such as what is the diameter of the cylinder, there is strict requirements, and positive and negative errors are qualified parts within the specified requirements, otherwise, they are unqualified parts; there are specific strict requirements for length, width and height The positive and negative errors are also specified. For example, an embedded cylinder (take the simplest basic Chinese mechanical part as an example). If the diameter is too large and exceeds the allowable range of the error, it will cause a situation that cannot be inserted. If the actual diameter Too small, exceeding the lower limit of the allowable negative value of the error will cause the insertion to be too loose, and the problem of instability will occur. These are all unqualified products, or the length of the cylinder is too long or too short to exceed the allowable range of errors. All of them are unqualified products and must be discarded or reprocessed. This will inevitably cause an increase in costs.
The requirements for the machining of precision China mechanical parts are actually the most important dimensional problems. We must process them strictly in accordance with the additional drawings. The actual dimensions processed will certainly not be exactly the same as the theoretical dimensions of the drawings. All are qualified China mechanical parts, so the requirement for precision China mechanical parts processing is to strictly follow the theoretical dimensions.
Second is advanced precision parts processing equipment and testing equipment. Advanced processing equipment makes the processing of precision parts simpler, higher accuracy and better results. The testing equipment can detect China's mechanical parts that have not met the requirements so that all products sent to customers can truly meet the requirements.
The above is an introduction to the requirements of precision China mechanical parts processing, I hope to help you.
