Precision parts processing requirements and standards

In terms of precision parts processing, it is quite strict, and the processing process has feed, knife and so on. There are specific requirements for the size, the accuracy is also relatively high, such as 1mm plus or minus how many microns, etc., if the size is wrong too much will become waste, at this time it is equivalent to having to process again, time-consuming and laborious, and sometimes even make a whole processing material completely scrapped, which leads to an increase in costs, at the same time, the parts are definitely not used. So what standards and requirements should be followed for precision parts processing?

For precision parts processing is the most important size requirements, such as camera parts diameter is how much, there are strict requirements, positive and negative error in the specified range of requirements is qualified parts, otherwise all are substandard parts; Length, width and height are also specific and strict requirements, and positive and negative errors are also specified, for example, embedded cylinders (take relatively simple basic parts for example); If the diameter is too large, beyond the allowable range of error, it is easy to appear, not inserted into the situation, if the actual diameter is too small, beyond the allowable negative error low limit, it is easy to insert too loose, unstable problems occur. These are unqualified products, or the length of the cylinder is too long or too short, beyond the allowable range of error, basically do not meet the requirements of the products, are needed to be scrapped, or re-processing, which is bound to cause cost increases.

In fact, it is the most important size problem, must be processed in accordance with the additional drawings, the actual size of the processing will not be the same as the theoretical size of the drawings, but as long as the processing size is within the error allowed range are qualified parts, so the requirements of precision parts processing is strictly in accordance with the theoretical size processing.

The second is advanced precision parts processing equipment and testing equipment, advanced processing equipment makes the processing of precision parts more simple, higher precision, better effect. Inspection equipment can detect parts that do not meet the requirements, so that all products sent to customers really meet the requirements.
