FEHLMANN PICOMAX 54 CNC milling machine

FEHLMANN PICOMAX 54 CNC milling machine was built in 2010 in Switzerland by FEHLMANN AG. This is an exceptionally efficient, multi-tasking machine that is ideal for processes requiring extreme precision. The machining processes, i.e. milling, drilling and threading, are performed inside a large workspace by means of a reliable high-speed spindle. In order to achieve high feed repeatability, all axes are equipped with special measuring systems, consisting of measuring scales and encoders. The open design, in turn, ensures free access to the workpiece. All this is complemented by the easy-to-use HEIDENHAIN CNC control with many useful functions. The FEHLMANN PICOMAX 54 drilling and milling machine weighs 2150 kg.
