        Precision machining is an indispensable mechanical manufacturing process in the field of modern science and technology and precision machinery manufacturing. If you want to realize precision machining, in addition to the numerical control equipment, workpiece materials, cutting tools, testing instruments and testing technology that should realize this process, the requirements for the environment are also very harsh. What are the requirements for the environment?
        The environment of precision machining can be different due to different functions, and its design has many aspects of technology, so it is a unique environment for different purposes. In view of this, it is necessary to comprehensively match the corresponding environmental conditions. For example, for steel, if the temperature changes by 1 degree Celsius, it is possible to produce 1um deformation for every 10cm length.
        In other words, for precision machining that requires 0.1um, there must be measures that can control the temperature change less than 0.1 degrees Celsius, and for devices that use light, small external gold exchange changes will cause the optical axis to shift.
        Therefore, there are also corresponding requirements for the thermal expansion and contraction of houses caused by small vibration, sunshine and temperature changes, as well as the impact of indoor air fluctuations and electromagnetic waves. It can be seen from here that the clean environment of precision machining is not only to ensure the cleanliness of the air;
        When setting up a clean environment for precision machining, it is not possible to set it separately. Instead, it is necessary to adopt a spatial serialization method to form a flow line from low level to high level. Only in this way, even when the environment is damaged, the ultra precision reading environment system can be protected. Part of the overall facilities of the precision environment is the structure that surrounds the precision environment;
        Jinan injection molding manufacturer reminds you that in the process of precision machining, a dust with a particle diameter of 0.3um will cause misjudgment and scrap. If air bearings or other precision bearings are assembled in the workshop without purification, the dust will roughen the surface of parts.
        Therefore, in order to carry out precision processing, it is necessary to establish a clean room. A clean room refers to a room that takes measures to control the dust and fine particles in the air as well as the indoor air pressure, temperature, humidity, air distribution, shape, speed, etc. within a certain range.
        In addition, it is also necessary to prevent the electrostatic environment, because static electricity will cause damage to semiconductor components, make the film sensitive, produce bubbles, adhere to dust and other particles, and cause production and quality accidents. Therefore, it is necessary to take measures to prevent objects from being charged. Follow our website for more relevant content http://www.lasagnafarm.com Come on!
