For some professional hardware processing factories, CNC precision zero processing is very strict, and its requirements are also the same. CNC precision parts processing procedures include cutting in, cutting out, etc., which have specific requirements for size and accuracy.
For example, if the size of 1 mm plus or minus micrometers is wrong, it will become waste. At this time, it is equivalent to rework, which is time-consuming and labor-intensive. Sometimes even the entire processing material will be scrapped, increasing costs. At the same time, these parts are absolutely not used.
For CNC precision parts processing, it is mainly the size requirements, as follows:
1. Such as cylindrical straight
What’s the diameter? There are strict requirements, and only the positive and negative errors are within the specified requirements are qualified parts, otherwise they are all unqualified parts;
2. There are also specific and strict requirements for length, width and height. There are also regulations for positive and negative errors. For example, an embedded cylinder (take the simplest basic component as an example). If the diameter is too large and exceeds the allowable range of error, it will cause. If it cannot be inserted, if the actual diameter is too small and exceeds the lower limit of the allowable negative value of the error, the insertion will be too loose and the problem of looseness will occur.
The above are all unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable range of error. These are unqualified products and need to be scrapped or reprocessed, which will inevitably lead to increased costs.
1. The requirement of CNC precision parts processing is actually the most important size problem. It must be processed strictly in accordance with the additional drawings. The actual processing size will certainly not be the same as the theoretical size of the drawing. However, as long as the processing size is within the allowable error It is a qualified part. Therefore, CNC precision parts are required to be processed in strict accordance with the theoretical size.
The second is advanced CNC precision parts processing equipment and testing equipment. Advanced processing equipment makes the processing of CNC precision parts simpler, more precise and better. Testing equipment can detect parts that do not meet the requirements, so that all products sent to customers truly meet the requirements.
We must pay attention to the requirements of CNC precision parts processing. As long as the requirements are met and combined with our own superb technology, we can bring precision workpieces to customers.
