The biggest feature of this platform is its ultra-high precision, with a flatness tolerance of ±0.002mm per 1000mm, meeting the requirements of national metrology standards and international precision machining specifications. Its low thermal expansion coefficient effectively reduces the dimensional error caused by temperature changes during the grinding process, ensuring the consistency of workpiece processing accuracy. The fine-grained granite structure has excellent wear resistance, which can withstand repeated grinding and scraping operations without surface damage, extending the service life to more than 15 years. The sealed edge treatment prevents grinding fluid from penetrating into the interior of the platform, ensuring long-term stability of the platform structure. In addition, pre-drilled mounting holes are available to facilitate fixed installation on the workbench.
Standard specifications include 300*300*100mm, 500*500*100mm, 630*630*100mm, 1000*1000*150mm. The surface is processed by multi-stage grinding and polishing to achieve a roughness of Ra ≤0.8μm, and each platform undergoes a 24-hour constant temperature aging treatment to eliminate internal stress and avoid deformation during use. The pre-drilled mounting holes are located at the four corners and the center of the platform, with a diameter of 10mm and a depth of 80mm, which can be customized according to customer requirements. All products are packaged with shockproof wooden cases to ensure that the platform is not damaged during transportation.
Mainly applicable to precision machining workshops, hardware measuring rooms, electronic component production lines, optical instrument calibration rooms, and aerospace parts processing workshops. It can be used as a reference platform for surface grinding, flatness measurement, workpiece calibration, and tool setting, providing accurate positioning and support for precision processing operations. It is also suitable for school teaching and scientific research institutions to carry out material performance testing and geometric measurement experiments. Additionally, it can be used for precision inspection of semiconductor components and optical glass parts.
