Model KVR-AV AUTO VALVE TYPE VACUUM CHUCKKVR / KVR-AV / VPU-E-AVAn epoch-making vacuum chuck that requires no masking!Vacuum systemrequired additionallyB1B2StopperLeP1Ball valve(3 places)Suction portP2Be(2)φ7φ2.5Suction portshapeHhEvacuateKVR-AV1530Patented(Technical tie-up withTaiyo Tec Company)Reverse jetL1L2Vacuum[Application]Nonferrous and nonmagnetic materials can be held and machined.These chucks are suitable for grinding plastics, aluminum, brass,stainless steel, ceramic and glass by machine tools. They can also beused for light duty cutting if workpieces can be held firmly.[Features]●No masking is required to reduce the setup time:Place a workpiece, apply grinding fluid and turn the valve. That is allrequired. Since the suction holes outside the workpiece areautomatically closed, troublesome masking is not required andgrinding can be started soon.●Easy valve cleaning:An original modular design that causes little clogging due to sludgefacilitates maintenance to reduce the running cost.●Enhanced safety:An original construction is employed that closes the auto valveinstantly should a workpiece move during grinding. This design causesno vacuum break and maintains a certain level of holding power.●Dry operations supported:In dry grinding operations using no grinding fluid, the chuck can beused with minimum necessary masking only.[mm(in)]Mounting FaceHeightApplicableMassSuction PortsVacuum SystemWork Face Suction Port Pitch No.ofModel Nominal SizeB?
