Demonstrated at IMTS, a patent-pending through-tool design cools the cutting edge more efficiently than equipment previously available. It can be combined with minimum quantity lubrication (MQL) for even greater speeds and tool life. MAG Industrial Automation Systems demonstrated the new US Navy-sponsored development that uses a through-spindle, through-tool cooling system. The multi-patent-pending development reportedly permits dramatically higher cutting speeds for increased metal removal, longer tool life, or a blend of the two. Early results indicate this technology, could improve the lifecycle cost model for machining in a hard-metal environment by reducing the required number of machines and associated plant infrastructure, or possibly increasing tool life. Cryogenic machining is not an environmental issue, according to MAG. There is no mist collection, filtration, wet chips, contaminated workpieces, or disposal cost. Energy consumption is reduced because the pumps, fans, and drives needed to handle coolant are eliminated.
