Dyna-Force® Clamps

Measurements Available: Metric

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.
