OK-VISE® Clamps
THREE-DIMENSIONAL MACHINING
Due to a low-profile design of OK-VISE® Clamps, it is possible to execute flexible three-directional machining of workpieces with one fastening. This ability to machine a workpiece in three planes means improved accuracy.
PULL DOWN ACTION
The single wedge clamps keep the workpieces steadily in place, not allowing upward or downward movement. The double-wedge clamps generate a pull-down action pressing the workpieces towards the fixture base.
MACHINABLE JAWS
Single-wedge clamps are also available with extended jaws that can be machined to suit the geometry of the workpiece.
SPECIAL MODELS
“E”: (Balls on each Jaw) A self adjusting serrated steel ball is helpful when clamping castings and workpieces of irregular shape.
“T”: Jaws tapped with M5 threads for socket head screws allowing for quick and easy use of various different additional pieces.
“SS”: BK2 is available in high quality stainless steel to meet the demands of EDM applications.
ECONOMY MODEL
“O”: Not ground as precise as standard models. Same raw material is being used and the bottom of the jaws are ground for precise locating on the fixture base.
