Requirements and process of precision hardware parts processing

Precision Hardware parts processing is a process that requires very high precision of hardware parts for hardware processing plants. In the process of precision hardware parts processing, it must have strict requirements and precise processing procedures, so as to ensure qualified and high-quality hardware products. Let's take a look at the requirements and processes of precision hardware parts in the processing process. Requirements for precision hardware parts: for example, when processing cylindrical hardware processing parts, there are strict requirements on the diameter of the cylinder, and the positive and negative errors within the specified requirements are qualified parts, otherwise they are all unqualified parts; For example, if the diameter of the embedded cylinder is too large to exceed the allowable range of the error, it will lead to insertion, and if the actual diameter is too small to exceed the lower limit of the allowable negative value of the error, it will lead to insertion. Insert too loose, there is an unsafe problem. The length of the cylinder is too long or too short to exceed the allowable error range. These are unqualified products and must be scrapped or reprocessed, which will definitely lead to increased costs. Secondly, advanced non-standard precision parts processing equipment and testing equipment, advanced processing equipment makes the processing of precision parts simpler, higher precision and better effect. About the processing flow of precision hardware parts 1. Familiar with the drawings of processing equipment and hardware parts: in order to be able to process the required precision hardware, you need to carefully check the hardware drawings before processing the precision hardware, be familiar with the shape and size of the required precision hardware. In addition, it is also necessary to be familiar with the production equipment of hardware. 2. According to the hardware parts to be processed, the material is opened: the material is cut, which means that the hardware materials of the appropriate specifications are selected according to the size and processing technology of the hardware to be processed. 3, processing precision hardware: processing precision hardware is to put the good materials into the processing equipment, according to the size of the precision hardware to process the raw materials. 4. Surface treatment of hardware parts: the surface treatment of hardware parts is to polish, Polish, spray or electroplating the surface of processed precision hardware.
