Among them, SK7520/H universal universal thread grinding machine is widely used for processing thread of precision screw, plug gauge, inner and outer cylinder and taper thread workpiece. It can also grind worm and various shapes of thread, such as triangular thread and trapezoidal thread. , ball screw, etc., can complete the helical gear of various profiles. The machine adopts many high-tech and unique artificial granite beds, which makes the machine have higher shock resistance, rigidity and thermal stability. The wheel seat adopts cylindrical structure, good rigidity and wide adjustment range of spiral angle. It can also be used for large-scale screw grinding.
zero order waveplate, also known as a compound zero order waveplate, consists of multiple waveplates of the same birefringent material that have been positioned so that they are perpendicular to the optical axis.China Zero Order Waveplate manufacturers, Cemented Zero-Order Waveplate, Crystal QuartzZero Order Waveplate,Cemented Zero-Order Waveplate,Crystal Quartz Waveplates,Multiple Order Quartz Waveplates Waveplates, Multiple Order Quartz Waveplates, we offered that you can trust.
