For precision parts processing, it is quite strict, the processing process has a tool in, tool out, etc.. For the size of specific requirements, the accuracy is also required to be relatively high, such as 1mm plus or minus how many microns, etc., if the size is too much wrong will become scrap, then it is the same as having to process again, time-consuming and labor-intensive, and sometimes even a whole processing material completely scrap, which leads to increased costs, and at the same time, the parts are certainly not used. So what standards and requirements should be followed for precision parts processing?
For precision parts processing is the main dimensional requirements, such as how much the diameter of the cylinder, there are strict requirements, positive and negative error within the specified requirements to be considered qualified parts, otherwise all substandard parts; > length, width and height are also specific and strict requirements, positive and negative error also have provisions, let's say the embedded cylinder (to take a relatively simple basic parts for example);, if the diameter is too large, beyond the error Allowed within the range, it is easy to appear, inserted into the situation, if the actual diameter is too small, beyond the error allowed negative low limit, it is easy to insert too loose, unstable problems occur. These are substandard products, or the length of the cylinder is too long or too short, more than the error tolerance range, basically do not meet the requirements of the product, are required to be scrapped, or processed again, which will inevitably cause the cost to increase.
In fact, the main problem is the size, must be processed in accordance with another drawing, the actual size of the processing will never be the same as the theoretical size of the drawing, except that, as long as the processing size within the error tolerance is also qualified parts, so the requirements of precision parts processing is in strict accordance with the theoretical size of the processing.
Second is the advanced precision parts processing equipment and testing equipment, advanced processing equipment makes processing precision parts easier, higher precision, better results. Testing equipment can detect the parts that do not meet the requirements, so that all the products sent to customers really meet the requirements.
