Uniforce clamps generate a strong lateral force using a single cam-driven screw that pushes the part into a fixed rail or locator. Their low profile and simultaneous jaw movement make them ideal for holding two or more parts at once in tight spaces. The steel jaws can be replaced with machinable aluminum inserts for custom setups. Great for repeat production, tombstone fixturing, or when maximizing machine table space.

Each model below is routed to the best next step based on availability.
Every changeover means idle spindle time. Multi-part fixturing slashes setup frequency — so your machines spend more hours cutting and less time waiting.
Based on 250 working days/yr. Multi-part fixturing reduces changeover frequency so your spindle spends more time cutting.
