High pressure ARNOLD TWIN vices are capable of clamping two pieces simultaneously. - Accuracy of 0.01 mm in clamping repeatability. - Suitable for working in horizontal and vertical machining centres. - Grinding of all surfaces with a parallelism and perpendicularity of 0.02 mm. - Possible working positions: supported on the base, on the side or on the head vertically. - Side windows for quick cleaning of the inside of the vices. - Clamping force is 25/50 kN, depending on the size. - Designed to automate processes and robotize them. - Fitted with a high pressure single acting oleo-dynamic spindle, with spring push-back effect. - Rotary connection at the inlet and the outlet for oil. - Automatic stroke for closing and opening 4 mm. - Adjustable clamping force directly proportional to the oil pressure input (see manual). ELEMENTS REQUIRED - Hydraulic unit or single acting 500 bar pneumo-hydraulic pump with vice unit connection hose, pressure control switch, safety valve integrated into the unit and ON-OFF switch. - Pressure gauge. CLAMPING POSSIBILITIES Two workpieces can be clamped at the same time, with a difference in size of 3mm. between them or just one workpiece.
