3-jaw chuck / manual tightening / lathe - ø 80 - 315 mm, 2700 - 5000 rpm
Often used in grinding operations, these chucks allow the operator to re-align the front body of the chuck and therefore the workpiece in relation to the spindle nose, thus giving increased accuracy of within 0.005mm. The chuck will then grip subsequent workpieces of the same diameter within 0.013mm. They can be used as normal chucks by leaving the front body in the centered position. Adaptor plates are available on request following minor modification from the standard design.
