Tajmac-ZPS MANURHIN K'MX 816 CLEVER

Eight linear axes for a 16 mm bar: the MANURHIN K'MX 816 CLEVER packs the most kinematics per millimetre of bar in the range. X1, X2, Y1, Y2, Y3, Z1, Z2 and Z3 plus C1 and C2 let four tools cut at one time, on two 12,000 rpm electro spindles of equal power, 3.7 / 5.5 kW each.

The layout is two independent cross slides beside the guide bush and one axial rack that moves in both Y3 and Z3. Because the axial rack has its own Z stroke of 225 mm, it can feed drills into the main spindle side or serve the counter spindle without waiting for the headstock. The vertical strokes are long for a small machine, 319 mm on Y1 and Y2 and 305 mm on Y3, which is how (2 x 10) + (2 x 6) tool positions fit.

Powered tooling is where this model differs most from the 20 mm machines. The two racks next to the guide bush carry gearboxes with 4+4 powered positions for ER16 collets at up to 8 500 rpm. The maker's example is milling parallel surfaces simultaneously or radially drilling holes against each other. The axial slide can optionally take 3 powered tools for the main spindle and 3 for the counter spindle, at up to 12 000 rpm, for work such as eccentric drilling. C-axis on both spindles is optional here, and a B-axis is listed as optional.

Standard bar capacity is Ø 16 mm with a Ø 21 mm bore; Ø 20 mm bar with a Ø 23 mm bore is optional on request. One clamping turns 220 mm. The counter spindle stroke is 345 mm and parts up to 160 mm eject from the front. FANUC 31i – Model B controls it. The machine is 2,000 x 1,280 x 1,740 mm and 3,500 kg, and draws 31 kVA.
