What are the requirements for precision parts processing
by：QY Precision 2020-03-16
For some more professional hardware processing plants, the processing of precision parts is very strict, and the requirements are the same.
Precision parts processing procedures include feeding and discharging, which have specific requirements on size and accuracy.
For example, 1mm plus or minus how many microns, etc. , if the size is too wrong, it will become a waste product, which is equivalent to reprocessing, time-consuming and laborious, and sometimes even the entire processing material will be scrapped, this leads to an increase in costs, and at the same time, parts are definitely not available.
For precision parts processing, it is mainly the size requirements, as follows: 1. For example, what is the diameter of the cylinder?
There are strict requirements, positive and negative errors are qualified parts within the specified requirements, otherwise they are all unqualified parts; 2.
The length, width and height also have specific and strict requirements, and positive and negative errors are also specified, such as an embedded cylinder (Take the simplest basic parts as an example)
If the diameter is too large and exceeds the allowable range of the error, it will cause the situation that it cannot be inserted. If the actual diameter is too small and exceeds the lower limit of the allowable negative value of the error, it will cause the insertion to be too loose, the problem of instability occurs.
These are all unqualified products, or the length of the cylinder is too long or too short, beyond the allowable range of the error, are unqualified products, are to be invalidated, or reprocessed, this will inevitably lead to an increase in costs.
The requirement of precision parts processing is actually the most important size problem. It must be processed in strict accordance with the additional drawings. The actual size of the processed parts will certainly not be the same as the theoretical size of the drawings,, as long as the processing size is within the allowable range of error, it is all qualified parts. Therefore, the requirement for precision parts processing is to process strictly according to the theoretical size.
Secondly, advanced precision parts processing equipment and testing equipment, advanced processing equipment makes the processing of precision parts simpler, higher precision and better effect.
The testing equipment can detect parts that do not meet the requirements, so that all products sent to customers can truly meet the requirements.
We must pay attention to the requirements of precision parts processing, as long as the requirements are in place and combined with their own superb technology in order to bring precision workpieces to customers.
