The core advantages of this granite guideway include its ultra-low thermal expansion coefficient, which ensures that the positioning accuracy remains stable even when the equipment runs for a long time and generates heat. It has excellent wear resistance, with a service life far longer than that of steel guideways, and does not require regular lubrication, reducing maintenance costs. It is non-magnetic, which will not interfere with the sensors and precision measuring devices on the equipment. The surface adopts ultra-precision grinding treatment to ensure smooth linear motion and low friction coefficient. It can be customized in length and profile according to customer needs, adapting to various types of CNC machine tools and automated equipment.
The standard width options are 100mm, 150mm, 200mm, and the length can be customized from 500mm to 3000mm. The mounting hole spacing can be adjusted according to customer requirements. The static load-bearing capacity reaches ≥5000kg, and the surface roughness is Ra≤0.2μm. The thermal expansion coefficient is ≤5×10^-6 per ℃, which meets the accuracy requirements of high-precision CNC machine tools. The product is packaged with anti-rust film and solid wood crates to avoid damage during transportation. It has passed CE certification for industrial machinery parts, ensuring compliance with EU safety standards.
It is suitable for linear guideways of precision vertical machining centers, linear guide rails of laser engraving machines, linear guideways of automated inspection equipment, linear transmission guide rails of semiconductor packaging equipment, linear motion reference parts of precision optical measuring equipment, and other high-precision motion control scenarios.
