4-sided automation clamp
Hydraulic 4-jaw chuck for automated workpiece clamping
HWR Spanntechnik presents the "INOFlex VF-A" variant from the "INOLine" product line. The company has developed the clamping device with automated workpiece changing in mind: The hydraulic actuation enables workpieces to be changed quickly and precisely, which significantly increases productivity, especially in automated operation.
The "INOFlex VF-A" clamping device is a hydraulically actuated 4-sided automation clamping device. According to the company, almost all part geometries can be covered with just one clamping device. The hydraulic actuation enables short times to be achieved when changing components - and therefore higher productivity in automated operation.
Typical applications include stationary use on milling machines, clamping of round, square or rectangular as well as geometrically irregular components. "INOFlex VF-A" is suitable for workpieces that are sensitive to deformation.
Three sizes available
Three sizes are currently available, with chuck sizes of 220 mm, 420 mm and 700 mm. The 4-jaw arrangement in a 90° pitch offers numerous combination options: For example, two opposing jaws can be used as centering clamps, while the two jaws not required remain unused or dismantled.
