Are you having trouble with dirt or scratches caused by the automatic dropping of perforated workpieces (food, cosmetic caps and inner plugs, small gears, etc.)? With the pad in pad, it is possible to suck and take out the perforated work. With the assembly of the outer bellows pad, suction metal fittings, hole closing pad, and middle metal fittings, the flat surface of the work is sucked with the outer bellows pad, and the hole is closed with the hole closing pad.
