HECKERT HEC 400 D DYNAMIC HORIZONTAL MACHINING CENTER

Technical Description

The Heckert HEC 400 D Dynamic Horizontal Machining Center is a high-performance 4-axis CNC machine designed for precision and efficiency. It features a horizontal spindle with an HSK A 63 taper (optional SK 40), capable of speeds up to 15,000 RPM (12,000 RPM optional), powered by a 44 HP spindle motor rated for 30 minutes, with an optional upgrade to 67 HP. The machine supports a 15.7" x 15.7" standard worktable with optional expansion to 19.69" x 15.7"; the maximum workpiece weight capacity is 1,100 lbs. The table supports include a standard indexed option with an optional rotary table. The tool handling system uses a chain automatic tool changer (ATC) with 60 tool capacity, expandable to 80 tools, and achieves tool change times of 2.7 seconds. A pallet changer is included as standard with two pallets. Axis travels measure approximately 25.6" in X and Y, and 26.77" in Z, with rapid traverse and maximum feed rates of 3,930 inches per minute. The control system typically uses Siemens Sinumerik 840D, ensuring precise multi-axis coordination. The machine exhibits dynamic performance with rapid traverses up to 65 m/min and accelerations up to 15 m/s² in high-speed versions, facilitating efficient machining of light metal, cast iron, and steel. Optional packages include a Power-Package for heavy-duty cutting and a Dynamic-Package optimized for light-metal machining at higher speeds and accelerations. The robust build ensures thermal stability and precise machining for complex, high-volume production environments.
