Diebold’s JetSleeve system is designed to reduce cutter breakage due to chip interference, extending tool life. The system consists of a ThermoGrip chuck with a modified nose contour and an aluminum sleeve with a series of 16 calibrated holes around the tool opening to ensure a constant supply of coolant or air to the cutting tool. The small size of these holes forces the air or coolant to accelerate to a high velocity, ensuring that chips or fines created by the machining process are flushed out immediately. As a result, the cutter doesn't run over chips, making it useful for lights-out machining, the company says. A single O-ring connects the sleeve and the toolholder.
Chucks are available for cutting tools with shanks ranging from 3 to 20 mm, and in all HSK and steep-taper sizes. Special lengths and variants are available as well. The system can be used with MMS units, air-only units, emulsion units or conventional through-tool coolant supplies.
