Pneumatic measuring instrumentPedestal and upper measuring tools of equal length that can indicate quantity values. Compared with the measuring tool, the measuring instrument has the advantages of high sensitivity, high precision and small measuring force, and its structure is more complicated. The measuring instrument requires higher environmental conditions and is generally used in the measuring room.Eileride focuses on pneumatic measuring instruments, focusing on micro-precision, providing high-tech measuring equipment and technical services for home appliances (compressors), automotive, aerospace (air), precision machining, semiconductor manufacturing and other industries.

Detect the condition and environment of the workpiece

The physical shape of the workpiece has a certain influence on the measurement result. The common is the surface roughness of the workpiece and the chips left by the processing. Coolant and oil also contribute to measurement errors. Usually, dust and dirt can be concentrated on the measuring ball and affect the performance and accuracy of the measuring machine. There are many similar situations that affect the measurement accuracy, most of which can be avoided, and it is recommended to carry out the necessary cleaning work before the measuring machine starts working and after the completion of the work.

Temperature condition

The main environmental factor affecting the measurement is temperature. This temperature must also be followed when the measuring machine is operated, but the actual situation is not so. The change of the ambient temperature of the measuring machine mainly includes: the change of the ambient temperature, the change of the short-term temperature, the change of the long-term temperature, the change of the temperature gradient. In order to ensure the measurement accuracy, each measuring mechanism manufacturer has strict limits on this.

Modern large-scale production, many measuring machines are directly used in the production workshop site, in view of the conditions of the production site often can not meet the temperature requirements, most measuring machine manufacturers have developed automatic temperature correction system.

The automatic temperature correction compensation system is based on the standard temperature correction based on the temperature expansion coefficient of different metals by monitoring the grating of the measuring machine and the temperature of the detecting workpiece parts. No compensation can be made for rapid temperature or temperature gradient changes.

Vibration

As more measuring machines are used on production sites, vibration becomes a frequent problem. For example, punching machines, air compressors, or other heavy equipment around the measuring machine will have a serious impact on the measuring machine. It is more difficult to detect small vibration, if it is confused with the vibration frequency of the measuring machine itself, it will also have a greater impact on the measurement accuracy. Therefore, the manufacturer of the measuring machine has certain requirements for measuring the vibration frequency and amplitude of the environment.

humidness

Relative to other environmental factors, humidity is not a big problem. In order to prevent the oxidation and rust of block gauges or other measuring equipment, it is required to keep the ambient humidity at40%The following.

Power supply: In order to ensure the good operation of the control system and the computer system and the external network, there are certain requirements for the power supply, including: power supply voltage changes, frequency requirements, and requirements for grounding devices and shielding devices

Compressed air

Many coordinate measuring machines require compressed air due to the use of precision air bearings. For the purchaser of the coordinate measuring machine, the requirements of the measuring machine for compressed air should be met to prevent the compressed air from affecting the measuring machine due to the intrusion of water and oil, and sudden gas cutoff should be prevented to avoid damage to the measuring machine air bearing and guide rail.
