This Monforts DNC 3 is a used lathe — sometimes referred to as a turning machine — dating from 1996 and currently located in Germany. Lathes are precision machine tools used to shape metal workpieces by rotating them against cutting tools, and are fundamental to the manufacture of shafts, bushings, and other rotationally symmetrical components. Monforts is a well-established German machine tool manufacturer with a long history of producing high-precision lathes and turning centres for the metalworking and engineering industries.
This machine is configured as a twin-spindle, twin-turret turning centre, making it suited to high-productivity machining where both ends of a workpiece can be machined in a single clamping. The main spindle and sub-spindle each have their own C-axis, enabling full contouring and the use of driven tools on both. Control is provided by a Siemens 840 C CNC system. Each spindle has a swing diameter of 530 mm and a turning diameter of 150 mm, with a spindle bore passage of 65 mm. Tooling interfaces are to VDI 30 (cylinder shaft DIN 69880) standard.
Each turret carries 12 tool positions, giving a combined capacity of 24 stations across the two turrets, all of which are driven tool stations. This allows milling, drilling, and other off-centre operations to be performed without removing the workpiece from the lathe. The axis travel figures for each spindle are identical: X-axis 175 mm, Y-axis ±70 mm, and Z-axis 433 mm. The Y-axis travel on both sides enables off-centre machining beyond what is possible on a standard turning centre without a Y-axis.
Spindle speed ranges from 38 to 4,000 rpm, covering both heavy roughing and fine finishing operations. Total installed power is 33 kW. The machine's footprint is 3.95 m long by 2.49 m wide, with a height of 2.6 m.
Included with the machine are collet fixtures for both the main spindle and sub-spindle, one collet for each spindle, a variety of tool holders including those for driven tools, various spindle reductions, a chip conveyor, and a coolant system.
