Monforts KNC 5

The Monforts KNC 5 is a cycle-controlled flat-bed lathe: it can be run by handwheels like a manual machine and switched to workshop programming on its CNC. Swing over the bed is 510 mm (20.1 in), swing over the cross slide 340 mm (13.4 in), and it comes with 1,000 mm (39.4 in), 1,500 mm (59.1 in) or 2,000 mm (78.7 in) between centres.

Monforts aims it at one-off and small series work and at users moving from conventional lathes. The standard control is the R&D cycle control MTC, with servo handwheels that let the operator step into a running cut, cycles for contours, threads and recesses, and a Teach In function that stores a part turned by hand and repeats it. A Siemens Sinumerik One is the alternative.

The headstock is geared. A mechanical 3-stage gearbox splits the 2 to 2,400 rpm range, and the drive is 11 kW (14.8 hp) at 100% ED and 15 kW (20.1 hp) at 40% ED. In first gear, 2 to 266 rpm, that gives 1,489 Nm (1,098 lb-ft) at 100% ED. Third gear covers 21 to 2,400 rpm with 166 Nm (122 lb-ft). The spindle bore is 80 mm (3.1 in).

X travel is 289 mm (11.4 in). Z travel depends on the bed, from 803 mm (31.6 in) to 1,820 mm (71.7 in). The base machine has a Multifix C quick-change tool holder for 32 x 32 mm tools, a manual tailstock with an MK5 taper and 200 mm (7.9 in) of quill stroke, a manual chuck of 250 mm (9.8 in) and a chip conveyor. An 8-position turret with or without driven tools, a hydraulic quill and hydraulic clamping are options.
