Better Vacuum Cups Inc. introduces SS-R200, the all-new round vacuum cup for all CNC routers. This Better Vacuum Cup comes in three standard heights such as 105 millimeters, 150 mm and 200 mm for the CMS fabricators. Like all BVC cups, this cup does not need the foam gasket to be used. The BVC flexible lip seal mirrors the part for a perfect lip seal, say officials.
