Classification of accuracy levels for marble platforms
The marble platform is a precision benchmark measurement tool made of natural stone materials, taken from high-quality rock layers underground, with extremely stable morphology and no need to worry about deformation due to conventional temperature differences. Below, the editor will take you to understand the accuracy level of the marble platform. The accuracy level classification of marble platforms can be divided into three accuracy levels, namely level 0, level 00, and level 000. Ordinary marble platforms have a precision of level 0, like a 300 * 300 marble platform. The precision error of level 000 is 1.5 micrometers, level 00 is 3 micrometers, and level 0 is 6 micrometers, which is considered a relatively high precision measuring tool. Although the accuracy of marble platforms is very high, there are requirements for their use. For example, marble platforms of level 000 must be produced in a constant temperature, dust-free, and vibration free workshop, and also need to be used under these conditions. Because this condition is not met during transportation, marble platforms of level 000 need to be processed in the user's constant temperature workshop. The common accuracy level of marble platforms is level 0, which can generally meet the production needs of the platform; If the requirements are high, it can reach level 00 or even level 000; Level 000 has a certain difficulty, requiring the material of the marble platform to be tightly organized, with an impact on water absorption and hardness; The platform has high requirements for the environment and foundation when reaching level 000. The environment should ensure constant temperature and humidity, and the foundation should have sufficient strength and vibration isolation performance.
