The company 1st Machine Tool Accessories (1st MTA) has introduced a series of cover plate kits that enable single-wedge machining clamps to provide an additional pull-down action.
Used in conjunction with inverted OK-Vise units, the new plate kits force the clamp's jaws to move outwards and downwards as they bear against the wedge's taper.
This generates high-strength grip, as well as a pull-down action that draws the workpiece securely onto the fixture base.
The kits also incorporate purpose-designed bushes, which improve the location of the inverted clamp by filling the recess normally occupied by the head of its tightening screw.
In addition, the bushes minimise base-plate thread wear in many high-volume applications by allowing components to be secured using a threaded stud and hexagon nut.
The cover plate kits can be supplied either as accessories for existing single-wedge clamps, or as complete sets including new B, D or F-series workholding units.
Capable of generating up to 150kN clamping force, the OK-Vises offer an extremely compact and cost-effective method of retaining workpieces against fixed stops.
They provide location in all three axes and are available in an extensive range of configurations to meet the demands of users throughout the metal-working, plastics, aerospace and electronics industries.
The clamps' low profiles also ensure excellent cutting-tool access and the ability to machine in three planes without re-positioning - for maximum accuracy and productivity.
