Dyna-Force® Clamps

The majority of the Dyna-Force® clamp is below the surface of the fixture which provides excellent clamp support and makes for a very low profile. The clamp jaw slides on an angle for positive downforce.

The clamp jaw is available with smooth or serrated faces.

The support surface of the Dyna-Force® clamp can be installed flush with the fixure plate or raised to hold the workpiece off the fixture, enabling drill-through.

  • Incredible Clamping and Hold Down Power
  • Low Profile, Compact Design
  • 17-4 PH Stainless Steel
  • Smooth or Serrated
  • Stainless steel screws and retaining rings are available for EDM applications

Dyna-Force® Installation

  • Bore ℄ of the hole "L" distance from edge of workpiece.
  • Drill and tap "H" to mount clamp in pocket.
  • Machine counter bore if recessing clamp into fixture.
  • Provide a back stop to locate the part.
NOTES:
  • "N*" – To have rest pad flush with fixture, use the dimension provided. To have the
    rest pad above the fixture surface, reduce the depth accordingly.
  • For dimensions I and J, use a tolerance of +.1/-0mm. For dimension L and O,
    use +.1/-.1mm.
