With the use of a CNC glass blowing lathe, the high precision for curved surface, slopes, slots, spherical surface, cylinder surface, hole diameter and cone angle are all achieved, as are highly difficult processing tasks. Precision glass parts all feature a long lifespan and high dimension precision (the tolerance: ±0.02mm). The hole diameter (min. diameter: 0.8mm), raw material, surface smoothness, shape, and roughness average are all customizable.
