Troy, Michigan – Heller’s FP 4000 5-axis horizontal machining center with twin drives in the Z-axis is a choice for industries, including tool-and-die or contract manufacturing, where 5-axis milling is needed for productivity and process dependability.

The FP 4000 provides work envelope accessibility with robust axis drives. The fifth axis provided by the tool and is the basis for achieving maximum process dependability. Proven 5-axis kinematics are provided by: the tool in X-, Y-, C-, and/or A-axis; and two axes provided by the workpiece in Z and B. The machine handles workpiece loads of up to 1,400kg on a 500mm X 630mm pallet. 

This machining unit, providing 44kW power and 242N-m torque, is among the most powerful 5-axis 10,00rpm spindles with HSK63 spindle taper. The power provided is available at any spatial angle, so the FP 4000 can do heavy-duty cutting, combined milling and drilling operations, or 5-sided machining in a single setup. Even in 5-axis simultaneous milling, the machine maintains dimensional and contouring accuracy as well as economic efficiency. A 16,000rpm, 40kW machining head is an option.

In combination with a flexible pallet system, system availability can exceed 90% without restrictions in terms of chip removal rate when equipped with the PCU 63 Power Cutting Universal swivel head unit. 

Precision down to the micron range is provided by absolute encoded, direct measuring systems, high-resolution rotary encoders, and YRT bearings with integrated measuring system. 

The machine is available with 54-, 80-, 160-, 240-, or 409-place tool magazine and Siemens 840D sl control.
