How strict are the requirements for precision parts machining? For precision parts processing is very strict; processing steps include tools, disassembly, etc.; there are specific requirements for size and accuracy, such as plus or minus 1mmμ If the wrong size such as the number of M is too large, it will become scrap, which is equivalent to re-processing, time consuming, destroying all the raw materials after processing, increasing costs, and the parts may not be usable.
In the machining of precision parts, the main dimensional requirements are, for example, the diameter of the cylinder, which is a strict requirement; positive and negative parallax only for qualified parts within the specified range, otherwise irrelevant parts; the dimensions also have strict requirements; negative parallax and positive parallax also need to be embedded in the cylinder (for example, very simple basic parts), etc. When the diameter outside the tolerance range is large enough, it cannot be inserted. If a specific diameter is small enough to exceed the negative tolerance limits, insertion looseness and instability problems can occur. These are non-conforming products, and cylinders that are too long or too short in length, beyond the allowable range, are extraneous goods that need to be scrapped or reworked, inevitably leading to increased costs.
In fact, mechanical parts processing requirements are the most important dimensional issues, must be processed in strict accordance with the drawings; processing of the specific size is difficult to agree with the basic theoretical dimensions of the drawings; only after processing the size of the tolerance range to meet the standard, so the requirements of precision parts processing is in strict accordance with the basic theoretical dimensions; secondly, precision parts processing machinery and testing equipment, precision production equipment that Processing precision parts easier, higher precision, and stronger actual results. Testing instruments can detect parts that do not meet the requirements, and all goods sent to customers can really meet the requirements.
