Pneumatic measuring instrument measurement is not accurate? After trying many methods, it still can't solve the problem? Below, list these 4 interference factors that are easy to ignore, eliminate verification one by one, and see if they are the cause of your measurement error?
First, the surface morphology of the workpiece will affect the accuracy of the measurement. The pneumatic measuring instrument has certain requirements for the shape of the workpiece. If the surface of the workpiece is rough, there will be obvious traces after processing, and the residual sawdust or other oil will cause the measurement data to be inaccurate.
Second, the coolant will affect the accuracy of the measurement. If there is coolant or other impurities on the surface of the workpiece, it may also cause measurement accuracy errors. Pneumatic measuring instrument in the use of the process should pay attention to cleaning problems.
Third, excessive vibration will affect the accuracy of the measurement. Pneumatic measuring instrument in the measurement process will inevitably produce vibration, small vibration within the allowable range, but if the measurement environment there are other heavy equipment such as stamping machine, air compressor, these equipment in the operation process will easily cause pneumatic measuring instrument measurement is not accurate. At the same time, users should also pay attention to the difference between the vibration of the mechanical equipment itself and the vibration caused by other external materials. These two vibrations are different, and the same is that they will affect the accuracy of the measurement.
Fourth, compressed air will affect the accuracy of the measurement. Compressed air is the main measuring medium of the pneumatic measuring instrument. Before use, it should be ensured that the air compressor can provide compressed air within the specified pressure range. At the same time, the cleanliness of the compressed air should be ensured to avoid the internal blockage of the pneumatic measuring instrument caused by the compressed air containing impurities., The measuring head and the surface of the workpiece are damaged.
