MAG IAS, LLC harrs licensed ICEFLY, a proprietary cryogenic machining technology, from Air Products for work in its machine tool manufacturing business, the company announced.
Cryogenic machining is a relatively novel process of applying liquid nitrogen to strong metals during machining, which turns the tool into a heat sink. The process reduces heat generation while machining and greatly lengthens tool life.
MAG has used the process in other machining operations, as you can see in the video here from Modern Machine Shop (MMS). As MMS describes the video, “The white mist in this video is the liquid nitrogen turning to gas as soon as it touches the air. The white on the tool is frost produced by the low temperature, despite the heat of machining.” MMS has a longer description of the process and its benefits here.
The announcement specified that Air Products will maintain its proprietary control of the technology, but allow it to be used with similar MAG technology. “Air Products has retained the registered trade name ‘ICEFLY’ and will continue to market ICEFLY® Cryogenic Machining Technology, a technology that enables a controlled jet of liquid nitrogen (LIN) to an application point,” Air Products Licensing and Technology Transfer manager Jeffrey Knopf explained. “Air Products will also continue to support existing cryogenic machining customers and explore new licensing opportunities outside of the MAG agreement.”
