German engineering traditions and WaldrichSiegen manufacturing heritage

The engineering background of WaldrichSiegen spans more than 185 years of dedicated machine tool innovation. Based in Siegen, North Rhine-Westphalia, Germany, the company integrates structural research, design departments, and assembly facilities.

Operating within the HerkulesGroup, WaldrichSiegen serves heavy industries worldwide, delivering heavy-duty machine tools to energy, maritime, steel, and aerospace manufacturing facilities.

Rigid machine foundations, high thermal stability, and tight machining tolerances define the performance standards of WaldrichSiegen equipment across global industrial installations.

Hydrostatic guideway engineering and dynamic vibration damping

A signature hallmark of WaldrichSiegen heavy machinery is the widespread implementation of closed hydrostatic guideways along linear and rotary axes. Pressurized oil cushions separate sliding structural members, preventing direct metal-to-metal contact regardless of cutting forces.

This arrangement completely eliminates stick-slip motion at micro-feed velocities and prevents mechanical wear of machine beds.

The viscous oil film provides superior dynamic damping that absorbs machining vibrations, enabling high-stock roughing passes and fine finishing within the same operational cycle.

ProfiMill heavy-duty gantry and portal milling centers

ProfiMill portal milling machines are built in multiple physical configurations, including moving table, fixed portal, and high-gantry layouts. The ProfiMill compact and ProfiMill evo lines allow operators to tailor structural dimensions to factory footprints and massive workpiece geometry.

Stiff mineral-filled or iron structures minimize thermal and mechanical deformations under extreme torque loads.

Automatic exchange systems handle orthogonal, angular, and multi-axis milling heads with high-resolution indexing, enabling uninterrupted multi-sided machining in a single set-up.

ProfiTurn H horizontal lathes and ProfiTurn M multi-tasking centers

ProfiTurn H horizontal lathes set international benchmarks for turning long rotor shafts, generator bodies, and mill rolls. Headstock spindles operate on precision hydrostatic bearings that provide high radial stiffness during heavy cuts.

Auxiliary milling units turn the lathe into a multi-axis center capable of milling slots, drilling holes, and cutting threads without workpiece transfer.

ProfiTurn M multi-tasking systems implement complete single-setup machining, finishing complex crankshafts and turbine rotors without intermediate handling steps.

ProfiGrind precision roll grinders for steel and metal rolling mills

Roll grinding precision directly dictates the surface quality of hot and cold rolled metal strip. ProfiGrind roll grinders produce exact roll crowns with sub-micron geometric tolerances.

The rigid bed structure and hydrostatic grinding wheel headstock ensure chatter-free operation, preventing chatter marks and runout flaws on roll bodies and roll journals.

An integrated C-frame measuring caliper continuously scans roll diameter and profile during the grinding run, sending real-time feedback to the CNC controller for profile compensation.

Routine maintenance practices and hydrostatic hydraulic system care

Sustained operational accuracy of WaldrichSiegen machine tools depends on systematic care of hydraulic power units and fluid filtration systems. Hydrostatic circuits demand continuous monitoring of fluid viscosity, temperature, and cleanliness levels to safeguard pressure valves and bearing pockets.

Regular seal replacements and scheduled CNC calibration maintain factory tolerances.

Qualified technicians recommend matched seal repair packages, high-pressure hydraulic lines, and specified filter elements compliant with factory maintenance schedules.
