Coordinate measuring machine (CMM) is a kind of high precision measuring instrument widely used in manufacturing industry. They can measure the three-dimensional position and shape of objects and provide very accurate measurements. However, the measurement accuracy of a CMM is affected by many factors, one of the most important factors is the geometric accuracy and surface quality of the granite components it uses.
Granite is a commonly used material in the manufacture of coordinate measuring machines. Its superior physical properties, such as large weight, high hardness, and strong stability, make it an ideal choice for dimensional stability and measurement accuracy. It has a small coefficient of thermal expansion, thus reducing the temperature drift of the measured results. Therefore, they are usually used as the reference platform, workbench and other core components of the CMM to ensure high-precision measurement results.
Geometric accuracy is one of the most basic elements in the processing of granite components. It includes the planar accuracy of granite components, the roundness, parallelism, straightness and so on. If these geometric errors seriously affect the shape and orientation of granite components, the measurement errors will be further increased. For example, if the reference platform used by the coordinate measuring machine is not smooth enough, and there is a certain degree of fluctuation and bulge on its surface, the measurement error will be further amplified, and numerical compensation is needed.
Surface quality has a more obvious impact on the measurement performance of the CMM. When processing granite components, if the surface treatment is not in place, there are surface defects such as pits and pores, it will lead to high surface roughness and poor surface quality. These factors will affect the measurement accuracy, reduce the measurement accuracy, and then affect product quality, progress and efficiency.
Therefore, in the process of manufacturing CMM parts, it is important to pay attention to the geometric accuracy and surface quality of granite parts to ensure its measurement performance. Cutting, grinding, polishing and wire cutting of the last process must be carried out in accordance with the standard, and the accuracy can meet the requirements of the manufacturing of CMM. The higher the precision of the granite components used in the CMM, the higher the measurement accuracy if it is properly maintained in daily use.
In short, the precision and surface quality of granite components are crucial to the measurement performance of the CMM, and paying attention to these details when manufacturing the CMM is the key to ensuring measurement accuracy and stability. Since the various structural parts of the CMM are made of granite, marble and other stones, when the quality is stable, long-term use or measurement in a wider range of temperature changes can ensure that the accuracy is stable, so as to ensure the accuracy and reliability of the production and manufacturing.
