Heat build up on dry machining operations reduces tool life and machining rates. The Cold Gun Aircoolant System from EXAIR (Cincinnati, OH) solves that problem and produces a stream of clean, cold air at 50°F (28°C) below supply air temperature. According to the company, operation is quiet and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolants cannot be used.
The Cold Gun is also an alternative to expensive mist systems. It eliminates the costs associated with the purchase and disposal of cutting fluids and worker related health problems from breathing airborne coolants or slipping on wet floors. EXAIR's Cold Gun is non-adjustable to prevent freeze-up during use.
