How accurate are used Zeiss CMMs?

Used Zeiss coordinate accuracy is affected by a variety of factors, the overall in reasonable maintenance and use, can maintain a higher accuracy, the following from a number of aspects for you to analyse:

 First, the equipment's own accuracy advantage of the

 advanced manufacturing process: zeiss as a well-known brand in the industry, in the manufacture of the three coordinate measuring instrument using advanced technology and high-precision parts and components. Its production process is strict, to ensure that the equipment in the design and manufacturing stage has a high precision basis. For example, the measuring system of ZEISS adopts high-precision scales and encoders, which can accurately measure the coordinate position and provide guarantee for high-precision measurement.

High-precision design: In the design of the equipment, ZEISS has fully considered the requirements of measurement accuracy. By optimising the mechanical structure and adopting advanced control systems and algorithms, the measuring accuracy and stability of the equipment are improved. For example, some high-end models of ZEISS adopt air bearing technology, which can reduce mechanical friction and vibration, thus improving the movement accuracy and measurement stability of the equipment .

Second, the key factors affecting the accuracy of the

 use of age and wear and tear: used zeiss coordinates of the use of age and wear and tear is an important factor affecting its accuracy. With the increase of the use of time, the mechanical parts of the equipment will be worn, such as the wear of the guide rail will lead to a decline in the precision of the movement of the equipment, the wear of the silk rod will affect the accuracy of the positioning of the coordinates. In addition, the electronic components will also be used with the increase in time and the phenomenon of aging, which may lead to a decline in the measurement accuracy and stability of the equipment .

Maintenance: The maintenance of the equipment also has a critical impact on its accuracy. Regular maintenance of the equipment, such as cleaning, lubrication, calibration, etc., can be timely found and solve the problems of the equipment, extend the service life of the equipment, to maintain the high precision of the equipment. On the contrary, if the equipment is not well maintained for a long time, it will lead to a decline in the performance of the equipment, the measurement accuracy is reduced, and may even cause equipment failure, affecting the normal production and work.

Use of environmental conditions: the use of environmental conditions on the accuracy of the used Zeiss CMM also has a greater impact. Coordinate measuring machine on the working environment of the temperature, humidity, vibration, dust and other factors have high requirements. For example, changes in temperature will lead to thermal expansion and contraction of the components of the equipment, thus affecting the measurement accuracy of the equipment; vibration will cause the equipment to produce errors in the measurement process, reducing the measurement accuracy. Therefore, if the equipment is located in the use of environmental conditions do not meet the requirements, will have a negative impact on the accuracy of the equipment .

Third, assess the accuracy of the practical method

 to view the calibration report: calibration report is an important basis for assessing the accuracy of the second-hand Zeiss coordinate. By looking at the calibration report, you can understand the equipment's latest calibration time, calibration organisation, calibration project and calibration results and other information. The calibration results in the calibration report should be in line with the requirements of the accuracy index of the equipment, if the calibration results are out of the range of the accuracy index, it means that there may be problems with the accuracy of the equipment, which need to be further checked and adjusted.

Conduct actual measurement inspection: Actual measurement inspection is the most direct and effective way to assess the accuracy of used Zeiss Coordinate. Through the use of standard blocks, standard balls and other standard parts with known size and shape for measurement, multiple measurements and record the results, and then compared with the standard value, calculate the deviation between the measured value and the standard value. The smaller the deviation, the higher the accuracy of the measuring machine. In addition, repeatability measurements and comparison measurements can also be performed to fully assess the accuracy and stability of the equipment .
