    ·If the clamping point exceeds the use range of the clamping force drawing, the bias load on the sliding part of the finger is too large, which will seriously affect the service life.

    Effective Clamping Force

    The expression of effective clamping force. The effective clamping force in the right figure refers to the state where four fingers and accessories are completely in contact with the workpiece. As shown in the figure below, the thrust received on one finger is expressed as f.When one of the two pairs of fingers on the opposite side damp the workpiece,the other pair is used for positioning; the clamping force of the MHS4 series should be the same as that of the MHS2 series.
