It is mainly composed of three parts:
granite base, beams and columns. It can be used with screw modules and linear motor modules to form a high-precision x, y, z three-axis linear motion system. It can be used in precision machine tool instrument positioning and optical defect detection. It is widely used in semiconductor equipment such as wafer dicing, high-speed inspection, and alignment bonding. It can perfectly replace metal castings, has no deformation and internal stress, and ensures parallelism and perpendicularity.
Compared with platforms and bases, granite gantry components can better meet the complex design needs of engineers in the horizontal and vertical spaces. The height and size of the columns are designed to be flexible, and the beam span can reach 2 to 3 meters. Metal castings of the same size have internal stress and earthquake resistance. The resistance and deformation caused by its own weight cannot be compared with that of granite components.
At present, granite gantry components are increasingly used in high-precision equipment such as optical fiber communication optical coupling equipment, mobile phone camera module alignment detection equipment, semiconductor eutectic machines, laser etching equipment, and backlight module defect detection, becoming a high-end An irreplaceable and important part of the equipment.
