The Monforts RNC 400 AC is a horizontal CNC lathe manufactured in 2000, designed for precision turning operations. It features a turning length of 600 mm and a swing over the bed of 410 mm, making it suitable for medium-sized workpieces. The machine is equipped with a robust spindle capable of reaching speeds up to 4000 rpm and a spindle bore diameter of 130 mm, allowing for versatile machining capabilities. This model includes a 12-station disc turret compliant with DIN 69880/VDI 3425/2 standards, with a 40 mm shaft diameter, supporting multiple tool changes for efficient machining processes. The turret is equipped with driven tools that have a maximum power of 13.6 kW (25% duty cycle), maximum torque of 28.9 Nm, and speeds up to 4500 rpm, enabling complex machining tasks including tapping without compensation chuck. The machine operates on two axes (X and Z) with travels of 410 mm and 280 mm respectively. It features AC servo drives with electronic safety monitoring, rapid traverse rates of 24 m/min on both axes, and feed forces of 7.2 kN (X-axis) and 10.7 kN (Z-axis). The C-axis offers rotational speeds from 0 to 25 rpm with a holding torque of 300 Nm. Additional equipment includes a separate guide rail tailstock with manual clamping, 900 mm travel, 90 mm quill stroke, and adjustable force up to 12,000 N (MT3). The machine has a 60° slant steel welded bed mounted on a reinforced concrete base with three-point support for stability. Hydraulic and cooling systems consist of a central pressure oil supply for hydrostatics and clamping, a 310-liter coolant tank, and a reinforced coolant pump delivering 3 bar pressure at 40 L/min. Power requirements are 3x400 V, 50 Hz with a total connected load of 20.5 kW (41 kVA). The machine weighs approximately 6800 kg and includes features such as a hydraulic hollow clamping device, parts catcher, A6 drawtube for collet chuck, and a 200 mm suction nozzle. Control is managed via a Monforts control system with a Siemens SINUMERIK display, offering programming in DIN 66 025 with high-level language extensions. The machine appears used, with some visible wear and dirt on the door and machining area, indicating prior operation but no specific details on operational condition are provided. The control panel includes multiple buttons and an emergency stop for safety. This lathe is suitable for users seeking a reliable CNC turning machine with extensive tooling options and robust construction. Horizontal turning machine manufactured in 2000. This Monforts RNC 400 AC features a turning length of 600 mm and a swing over bed of 410 mm. It is equipped with a 12-station disc turret and a maximum spindle speed of 4000 rpm.
