In the manufacturing industry, precision small parts processing is a market with strong growth. The demand for these components in the medical, hydraulic, connector, automobile, information electronic technology and household appliance industries has risen rapidly. In addition, in the aerospace and national defense industries, equipment control systems are increasingly equipped with electronic and hydraulic components, so suppliers in these industries have also become active users of small tools.
The processing of precision parts is mainly about size requirements, such as the cylinder diameter. There are strict requirements. Only qualified parts with positive and negative errors within the specified requirements, otherwise they are unqualified parts; There are also specific and strict requirements for length, width and height, and there are also provisions for positive and negative errors. For example, if the diameter of an embedded cylinder (take the simplest basic components as an example) is too large and exceeds the allowable range of errors, it will result in failure to insert. If the actual diameter is too small and exceeds the lower limit of allowable negative values of errors, it will result in too loose and unstable insertion.
Precision parts processing is difficult to compete with large European and American companies in terms of technology innovation and commodity research and development. However, with the influx of foreign capital and the intensification of the work competition, the domestic machinery parts processing work has increased its investment in independent development, which has already achieved infinite results. In particular, the mechanical measuring instrument manufacturing company has broken through in digital display skills and digital display hardware measuring tools.
Before the processing of precision parts in Shenzhen, check whether the moving part is filled with lubricating oil, then start and check whether the clutch and brake are normal, and idle the machine for 1-3 minutes. It is strictly prohibited to operate in case of mechanical failure. When replacing the die, first turn off the power, and then start to install and debug the die after the punch movement department stops running.
After installation and adjustment, move the flywheel by hand to test punch twice, and check whether the upper and lower molds are symmetrical and reasonable, whether the screws are firm, and whether the blank holder is in a reasonable position. All employees shall check whether their clothes meet the work requirements before entering their posts.
