With the same cutting tool and cutting parameters, semi finishing and finishing can correct various geometric errors of cutting tools and elastic deformation of parts, It is easy to ensure the size and finish machining the important bottom surface. Don’t think that high-precision parts processing is a common processing without paying attention to it. If we ignore some details, it may have a great impact on the processing of parts, so what are the matters needing attention in the processing of high-precision parts?
1. For high-precision parts, the processing is very strict, and the processing procedures include feed in and out. Computer gong processing Dongguan computer gong processing high speed CNC machining mechanical parts CNC machining CNC machining there are specific requirements for size and accuracy, such as how many micrometers are 1 mm plus or minus. If the size is wrong too much, it will become waste. At this time, it is equivalent to reprocessing, time-consuming and laborious. Sometimes, the whole processing material will be scrapped, which will increase the cost The parts will definitely not work.
For example, there are strict requirements for the size of the cylindrical parts, otherwise, there is a strict requirement for the diameter of the parts; There are strict requirements for length, width and height, as well as positive and negative errors. For example, for an embedded cylinder (take the simplest basic parts as an example), if the diameter is too large and exceeds the allowable range of error, it will cause the situation that it can not be inserted. If the actual diameter is too small and exceeds the lower limit of allowable negative error value, it will cause the problem of too loose insertion and not firm. These are all unqualified products, or the cylinder length is too long or too short, beyond the allowable range of error, are unqualified products, are to be scrapped, or reprocessing, which will inevitably cause the increase of cost.
3. The requirement of high-precision parts processing is actually the most important dimension problem. It must be processed in strict accordance with the additional drawings, such as computer gong processing, Dongguan computer gong processing, high-speed CNC processing, mechanical parts processing, CNC processing, and the actual size processed by CNC processing is certainly not the same as the theoretical size of the drawing, but as long as the processing size is within the allowable range of error, it is qualified zero Parts, therefore, the requirements of precision parts processing is strictly in accordance with the theoretical size of processing.
4. The second is the advanced precision parts processing equipment and testing equipment, advanced processing equipment makes the processing of precision parts more simple, higher precision and better effect. The testing equipment can detect the parts that do not meet the requirements, so that all products sent to customers really meet the requirements.
