Kennametal and Haimer develop most rigid and precise modular tooling interface

Via the new modular interface for carbide cutting tool heads, Duo-Lock, the pair are offering "the most rigid and most precise interface in the marketplace", which is "virtually unbreakable". For the first time, a modular milling system can achieve similar high performance of a latest-generation solid carbide end-mill, say the pair. Explains Oliver Sax, director product management at Haimer: "The current existing modular tool systems have their weakness in the interface. Due to this fact, the full potential of the cutting heads can`t be used, because of tool breakage." And Colleen Cordova, vice president industrial marketing at Kennametal, adds: "Haimer and Kennametal have been able to create a modular interface based on maximum stability that allows the user to make full use of the carbide tool potential." Highlights Doug Ewald, director product management system tooling at Kennametal: "The system provides 5 micron runout accuracy and a Z accuracy of 10 micron, which will eliminate most of the expensive presetting processes." Like the Safe-Lock system, Duo-Lock will be licensed to leading high-end cutting tool companies to establish a compatible, high performance modular end-mill system. Both Kennametal and Haimer introduced products at the recent IMTS exhibition in Chicago, with a new portfolio of cutting heads and mono-block screw-fit toolholders with Duo-Lock technology in all relevant spindle interfaces and extensions offered.
