  • Eclipse 12-100 Rotary Transfer Machine
    This just may be the Rotary Transfer machine you’ve been waiting for. A Machine Like No Other he new Eclipse 12-100 is a ground-up redesign of the famous Hydromat concept with all new components. It Tfeatures a heavy duty cast iron machine frame that is 2m in diameter, nearly twice as large as the traditional 12 station Hydromat machine. This machine platform offers multiple tool spindles in a single footprint integrated with one chip management & coolant system. Robot load/unload with auto inverting offers six-sided machining capability on both bar and blank loading applications. Each of the 12 tool spindle modules features 3-axis or 4-axis capability with all electric servo spindles and high-tech components such as heavy-duty linear guideways for high accuracy, and large bearing diameters for extra stability, that yield smoother cutting at higher speeds. The Eclipse CNC control has fixture mapping capability for exceptional station to station accuracy. Designed to be exceptionally rigid, these modules were designed with hefty castings for superior vibration dampening properties and maximum precision. The Eclipse offers a high degree of machining flexibility derived through engineering expertise coupled with a visionary concept, the type of creative thinking that has produced this superior Rotary Machining Center for small to large batch production. 1 FANUC 30iB CNC Control ECLIPSE 55/250 4-Axis Profile Toolspindle Module ECLIPSE 55/250 3-Axis Toolspindle Module Max.

The group provides solutions for virtually any manufacturing task, based on an extensive, long-standing expertise in milling, turning and gear making applications. At the AMB 2016, FFG presents its premieres and highlights at three dedicated stands – in hall 3/C18, hall 5/A11 and hall 8/A75. These include an automated production cell for cylinder crankcases with thermal-coated cylinder bores by MAG and our partner STURM group, versatile machining centers from Hüller Hille, Sigma and Feeler, leading turning technology from Hessapp, VDF Boehringer and Leadwell, innovative gear manufacturing technology from Modul, and advanced systems for high volume production from Pfiffner, Witzig & Frank and IMAS. The show is dedicated to giving impulses for modern manufacturing under the motto Smart Production Systems: Intelligent components, machines, processes and systems, designed as flexible, scalable, integrated systems and networks. These include various new products and services focusing on production data analysis, as well as service optimization. An example is the „Solution Wizard“, a guided trouble shooting tool for operators, utilizing CNC data for a web based analysis, customized search algorithms and fault analysis models. In line with the overall topic of digital networking, FFG will set up a direct line to IMTS together with its both neighbor KUKA in hall 8/A75, presenting a fully automated cell from the joint Industry 4.0 initiative of FFG, Siemens and KUKA.
