How to reduce the influence of air pressure on the coordinate measuring machine? Post time: 2019-11-28 Source: https://www.microaccuracy.com/ The measurement process of a coordinate measuring machine is susceptible to various interferences. Air pressure is one of the factors that have a greater influence, and the coordinate measuring machine is generally Air bearing is used. The air pressure will directly affect the operation of the equipment. How to reduce the influence of air pressure on the coordinate measuring machine? CMM has certain requirements for compressed air. Under the premise of normal working pressure, the floating gap of the air flotation block is about 4-12μm. The fluctuation of air pressure will change the air flotation gap of the air flotation block and affect the three-coordinate measurement. Repeatability of machine measurement. Moreover, when the air pressure is severely insufficient, the air flotation block will not fully float and cause friction with the guide rail. The lighter one will affect the motion state and measurement accuracy of the three-coordinate measuring instrument. A coordinate measuring machine with a pneumatically balanced axis will cause the Z-axis to be unbalanced and falling when the air pressure is severely insufficient. Therefore, try to ensure the stability of the working pressure of the coordinate measuring machine. The following measures can be taken: 1. The coordinate measuring machine To choose a suitable air compressor, it is best to have another air storage tank, so that the air compressor has a long working life and stable pressure. 2. The starting pressure of the air compressor must be greater than the working pressure. 3. When the coordinate measuring machine is turned on, the air compressor must be turned on first, and then the power supply must be turned on. 4. The compressed air output from the air compressor contains a lot of impurities such as moisture, oil and dust. A pre-filter can be used to properly remove these impurities to prevent them from harming the normal operation of the pneumatic system. Reducing the influence of air pressure on the coordinate measuring machine can reduce the appearance of measurement errors, so this is a situation that the operator needs to pay attention to. At present, the coordinate measuring machine plays a huge role in the precision inspection in various fields. Miaoji Technology has a variety of high-quality coordinate measuring machines and one-button measuring instrument equipment to provide!
