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.
