Setup and cycle times are the critical factors, particularly for series production. Due to the twin clamping, the NC-Compact twin vices from RÖHM are predestined for efficient machining. Two movable clamping jaws and a stationary center jaw enable high repeatability of 0.01 mm as well as constant clamping force for each clamping operation.
The moveable clamping jaw is adjusted up to the workpiece by turning the spindle in a clockwise direction with the hand crank and held with ca. 1 kN (third manual function). By continuing to turn the hand crank, the other clamping jaw is also placed on the workpiece and secured. The force is built up via the mechanical spindle. The balance springs compensate for dimensional differences of up to ±3 mm from workpiece 1 to workpiece 2.
