Heckert HEC 1250 U5
5-axis machining center
Flexible and modular-designed horizontal machining centers HEC 1250 U5 ensure optimum results in the economic machining of workpieces with an edge length up to 2,400 mm and a maximum weight of 5,000 kg.
By means of the NC swivel head the HEC 1250 U5 enable high-precision 5-axis machining of complicated workpiece shapes in milling, drilling and thread machining. Mould parts can be machined in any position within the swivel angle ± 180 °.
The highly flexible modular principle on the basis of Athletic machines series ensures individually customized solution for single-item, series or large-scale. Fields of use of the monitoring machining centers are primarily the area of Transport & Industrial Components. The machining centers can be delivered as stand-alone machines, added with pallet storage system or integrated in flexible production systems for unattended production
Key benefits:
• Customized version: Modular construction guarantees customizable manufacturing solutions
• Reduction of manufacturing and floor-to-floor times: Assembly-ready complete machining in one clamping
• Machining quality to IT 5/6 and high long-term accuracy:
– Thermo-symmetrical machine design
– FEM optimized main components
– use of high-precision functional elements
– high accuracy package as an option
• Reduction in setup times: workpiece setup on separate loadunload station during processing
• Decrease in non-productive time: highly dynamic tool handling and adjustment axes
• Savings on tool and operating costs: modern process monitoring and high energy efficiency of the machining centers
• 5-axis machining with NC swivel head
– High material removal rate thanks to powerful AC main motor with 2-stage gear
– Compact, rigid and torsion-resistant working spindle with a smooth running and long term accuracy
– Electronic spindle leveler and hydraulic clamping of the NC head for stable, safe and precise location position
– Automatic compensation of thermally induced axial spindle elongation for high positioning accuracy
– High dynamics of the pivoting movement of the NC head by direct-drive torque motor
