Dyna-Force® clamps use a unique cam mechanism to apply consistent lateral pressure while keeping the top of the part clear for machining. These clamps provide uniform holding force regardless of part size variation and are excellent for clamping castings, thin-walled components, or soft materials were downward pressure might distort the part. Their modular base design allows for precise positioning along fixture rails or plates.
| Key Features | |
| Edge-Only Clamping | Keeps top of part accessible for full-surface machining |
| Consistent Force Output | Independent of part size or variation |
| Modular Base | Easily repositions along standard fixture rails |
| Low Distortion | Ideal for thin or flexible parts that deform under vertical pressure |
| Repetitive Accuracy | Maintains consistent hold across batches |
