Kosmek USA Ltd., Bridgeview, Ill., has introduced the Q series of compact, pneumatic quick-change clamps designed for electric injection presses up to 350 tons. The air clamp generates 1 to 6.3 tons of force using normal shop air. A patented internal cam generates the clamping force while an internal lock keeps the tool safe if air pressure is removed. The clamp is priced lower than a hydraulic system, while eliminating the possibility of contamination around the clamp due to oil leakage. The clamps are available with a fixed mount or T-slot mount.
