Low-profile clamps come in two basic models, one with a single-wedge and the other with a double-wedge construction. In addition, OK-Vise®  offers a line of machinable jaw models for workpieces of irregular shape and a special model for casting and wire EDM applications

Standard models come with a hardness of 48-52 HRC and the jaws are serrated or smooth, depending on model. Both the wedge and the jaws are made of tool steel and are through hardened. Fastening operation involving one bolt (M5-16) ensures quick set up times.

OK-Vise® Operating Principle

OK-VISE® low-profile clamps function on the principle that when tightened down they expand, simultaneously thrusting the pieces to be machined against the guide and preventing any possibility of play. These clamps are designed to fit between the pieces to be machined and take very little space on the fastening base.

Accuracy of the fixture comes normally from the precision of the fixed stoppers, guideframes and location pins (so-called 0-points) not from the clamp itself which job is to generate the clamping force to hold the workpiece towards the 0-points.  OK-Vise®  has designed three models to meet the demands of regular workholding when ultimate precision is not a necessity.  Although not ground as precise as standard models these clamps are just as effective when it comes to clamping force. The bottom of the jaws is ground for precise locating on the fixture base.

AK2-VT-SO is the latest addition to the line of low-profile clamps. This "micro" clamp is designed for M5 socket head screw and is suitable for clamping relatively small workpieces. AK2-VT-SO always comes with smooth jaws and Viton o-rings instead of the regular springs.

BK2-VT-O comes with Viton o-rings and serrated jaws. Regular springs are available on request.
