In the field of industrial precision machining, the movement smoothness and trajectory accuracy of XYZT precision gantry movement platform are crucial. After using granite components, the platform has achieved a qualitative leap in these two aspects, providing a solid guarantee for high-precision processing.
Natural damping features suppress vibration
The internal structure of granite shows a unique crystal arrangement, which gives it good damping performance. When the platform is in motion, especially when the high-speed reciprocating movement, the vibration generated by the motor drive, mechanical transmission, etc., will pose a challenge to the smoothness of the movement. Granite components are like an efficient "shock master", which can effectively absorb and attenuate these vibration energies. The research shows that compared with ordinary metal components, granite components can reduce the vibration amplitude of the platform by 60%-80%. In the actual processing scenario, such as high-speed milling operations of 3C product parts, XYZT platform is equipped with granite components, which can significantly reduce the vibration of the tool in the cutting process, reduce the machining surface roughness by 30%-50%, and make the workpiece surface smoother, greatly improving the product quality.
High rigidity ensures smooth movement
High speed reciprocating motion requires high rigidity of platform components. Granite has excellent rigidity, compressive strength up to 200-300MPa, in the platform movement brought by the huge inertia force and impact, almost no deformation. In the process of rapid reversal of the platform, the ordinary material components may cause slight deformation due to the force, resulting in movement delays and affecting the accuracy of the trajectory. The granite components, with high rigidity, can ensure the stable operation of the platform moving parts and maintain a constant speed and direction of movement. For example, in the grinding processing of optical lenses, XYZT platform needs to drive the grinding tool high-speed reciprocating movement, granite components to ensure that the platform in frequent reversal, the movement trajectory deviation is controlled within ±0.01mm, precise control of the grinding force and position, so that the surface smoothness of the lens to achieve nanoscale accuracy, to meet the optical instrument's high precision requirements for the lens.
Structural stability optimization transmission connection
The structure of granite components is compact and uniform, which is not easy to be damaged by fatigue in long-term use, and provides a stable and reliable support foundation for the platform's transmission system. During high-speed reciprocating movement, the transmission components of the platform such as lead screw and guide rail work together with the granite components. Due to the stability of the granite components, the connection between the transmission components is more smooth, reducing the phenomenon of stuttering caused by the change of the matching gap. In the slating process of semiconductor chip manufacturing, XYZT platform needs to carry out high-speed and frequent cutting movement in a very small chip area. Granite components ensure the accurate operation of the transmission system, and the cutting position accuracy can reach ±0.005mm, effectively avoiding problems such as dislocation and edge breakage in the chip cutting process, and improving the yield of chip manufacturing.
