4-5 axes machining center Heckert Large

universaltraveling-columnhigh-rigidity

Large 4- and 5-axis universal machining centres from 1000 to 1800 mm pallet size. The flexible and modular-designed horizontal 4 and 5 axis machining centers enable complete and multi-side machining in one clamping position, reducing production and processing times, increasing the quality of processing, and minimizing logistics effort. The model series offers four sizes, a wide range of workspindle variants, process-optimized solutions for tool and workpiece handling, and innovative process controls and monitors. - 5-side machining in one clamping - Maximum dynamics in positioning mode and simultaneous operation - High rotational accuracy through 4-fold precision bearing - Optimal machining with max. 67 kW and up to 8,000 rpm - Serrated ring couplings guarantee highly precise swivel position - Automatic compensation of axial spindle extension under heat and sag compensation The flexible and modular-designed Heckert Large HEC Series guarantee optimum results in the economic processing of large-sized and heavy workpieces with an edge length of up to 3,600 mm and up to 15,000 kg in all material qualities. Modern machine concept: - Compact machine design with movable column - FEM optimized modular components - Functional groups with a low number of components - Central arrangement to reduce maintenance - High static and dynamic stability ensures optimum cutting performance - Closed frame standards for high rigidity and accuracy - Extremely large working areas with optimal travel paths and lifting positions of working spindle - Large distances between guideways Fields of Application: - V12 Engine block: 15% increase in efficiency thanks to pick-up tools and NC quill - Locomotive engine: Saving 39% processing time by reducing non-productive time - Cam chain cover: 32% increase in productivity thanks to multi-sides clamping Spindles: - Compact, bend-resistant spindle with high torsional stiffness, modifiable in power up to 82 kW and speed up to 12,500 rpm - Material removal rate in steel processing 1,800 cc/min - 4-fold precision bearing ensures high accuracy and smooth running Wide range: - Powerful horizontal spindles, modified power & speed - Horizontal/vertical milling heads for 5-side machining - NC quills for low-lying form elements and long travels - NC swivel head for all-round machining (Heckert HEC 1000 U5, 1800 U5) Energy efficiency: - Drive system: Energy recovery when axes are braking, use of servo drives with high efficiency, energy use according to demand, warm-up program supports resumption of production without delay - Hydraulic with accumulator charging circuit: Most efficient strategy to supply hydraulic energy, pressure-free oil circulation reduces base load and energy requirements and improves oil quality - Coolant high-pressure circuit: Automatic shutdown of the pump motor, pressures and pump outputs can be adapted, use of variable pressure reducing valves, speed-controlled pump motor (optional) - Compressed air: Automatic shutdown, use of high quality pneumatic systems, full functionality at low system pressure of 5 bar - Cooling systems: Operate in intermittent mode with low switching frequency, interface for central cooling-water connection for further energy saving - Optimized mechanical system: Use of low-friction roller-bearing guides in all linear axes Machine sizes: Huge, modular and flexible. Edge length up to 3,600 mm and up to 15,000 kg workpieces.
