Automatic description (AI-Generated)
This Monforts RNC 400 A CNC horizontal turning machine, manufactured in 2001, is designed for precision turning tasks with robust construction and advanced control features. The machine offers a swing over bed of 410 mm and a turning length of 600 mm, suitable for medium-sized workpieces. It is equipped with a spindle bore diameter of 130 mm and a spindle speed reaching up to 4000 rpm, powered by a 30 kW three-phase induction motor. The machine provides X-axis travel of 410 mm and Z-axis travel of 280 mm, allowing versatile machining operations.
The turning machine features a 12-position disc turret compatible with DIN 69880 / VDI 3425/2 standards and a 40 mm shaft diameter (VDI 40), enabling efficient tool changes and multi-tool operations. The turret uses directional logic and plane gear positioning for precise tool indexing. The machine's feed drives are servo-controlled with electronic safety monitoring, delivering rapid traverse speeds of 24 m/min on both X and Z axes, and feed forces of 7.2 kN and 10.7 kN respectively.
Additional technical details include a tailstock mounted on a separate guideway with manual clamping, providing 900 mm travel, a 90 mm quill stroke, and 12,000 N force capacity. The machine incorporates hydrostatic guides on the X-axis and a 60° slant bed steel welded construction mounted on a reinforced concrete base with 3-point support for stability.
Hydraulics include a central pressure oil supply for hydrostatics and clamping, along with a hydraulic hollow clamping device accommodating up to 65 mm bar capacity. The coolant system features a 310-liter tank delivering coolant at 3 bar pressure and 40 liters per minute flow rate.
Control is managed via the Monforts Control System with a Siemens Sinumerik display, supporting DIN 66025 programming, 2D/3D simulation, RS-232C serial interface, tool compensation for up to 600 tools, constant cutting speed, and thread cutting/tapping functions. The control panel is intact and includes an emergency stop button for safety.
The machine weighs approximately 6800 kg and operates on a 3x400 V, 50 Hz power supply with a total connected load of 20.5 kW (41 kVA). Visible components include the chuck, tool holder, and a blue coiled air hose hanging on the machine door. The machine shows signs of use such as some paint chipping on the door but overall the control panel and external parts appear in good condition. This Monforts RNC 400 A is a solid choice for shops requiring reliable CNC turning capabilities with comprehensive tooling and control options.
