The premiumautomatic valve typemulti-hole vacuum table(Premium Vacuum Table), we can also call it vacuum table without gasket. Used in CNC machining centers and engraving machines, Adopts an independent automatic valvein everysuction hole. When the surface of the suction hole is not covered by the workpiece, the internal valve of the suction hole automatically closes. When the surface of the suction hole is covered by the workpiece, the internal valve of the suction hole opens. Form an air pressure difference on the upper and lower sides of the workpiece, and the workpiece is firmly sucked on the surface of the vacuum chuck table. The Irregular shaped thin sheet workpiece can also be sucked easily. Even though the workpiece is milled through, which does not affect the normal work of the suction hole in other places that are not milled. The internal valve is a non-spring valve, to ensure that the vacuum table suction hole will not be blocked in the face of a lot of powdery debris which produced by aluminum alloy, ceramic, quartz, glass, glass fiber and graphite. Compared with theProfessional Vacuum Table, There are denser suction holes and stronger suction. The built-inair storage cabin technologyensures that only one switch is enough to control all suction holes. At the same time, the suction force of a single suction hole is improved.
