Vacuum suction table using granite
Our company offers a "stone vacuum suction table" that can securely hold thin and lightweight workpieces on a highly precise flat surface without distortion, enabling precise coating processes, inspections, and various types of machining.
By roughening the surface, we suppress charging during the detachment of glass substrates and prevent electrostatic breakdown of transistors formed in a glass-like manner.
Additionally, we can achieve a surface roughness of approximately Ra 0.5 while maintaining flatness, compared to the standard lap surface finish of Ra 0.8.
【Features】
■ As it is made of natural stone, there is almost no aging change.
■ It has low thermal conductivity, making it less susceptible to temperature changes, thus maintaining flatness.
■ Even if scratched, there is no "rebound," so flatness is maintained.
■ It is corrosion-free, clean, and maintenance-free.
■ When the workpiece is a glass substrate, it can suppress the generation of static electricity.
