Tajmac-ZPS MORI-SAY TMZ642CNC

Each of the six spindles on the MORI-SAY TMZ642CNC has its own external AC drive. That one design decision defines the machine: spindle speed is set independently per station, any spindle can be stopped or positioned, and the maker goes as far as calling the result a multifunctional machining centre. It is a six-spindle CNC automatic for round bar up to Ø 42 mm (1.7 in), with 5,000 rpm spindles of 7 kW nominal output.

The brochure lists what the external drives avoid. There is no reverse indexing of the drum after six pieces, no connecting and disconnecting of a drive at each indexing, and no drum heating from built-in electric spindles. Idle time is given as 0.7–1 s. Spindle torque is 66.8 Nm at 1,000 rpm on a pitch circle of 340 mm.

Standard motion comprises 26 CNC controlled axes, with a further 22 auxiliary axes available for optional accessories. Six longitudinal slide rests on W1–W6 have a working stroke of 360 mm. Five compound slide rests sit in positions I to V: 160 mm of Z stroke on the first two, 120 mm on the other three, and 80 mm on X. The parting-off slide rest, X6, strokes 66 mm. Compound slides with a Y axis in positions 2, 3, 4 or 5 are optional, as are driven tools, a pick-up spindle and counter-spindles rated 6,000 rpm.

Two Siemens SINUMERIK 840D Solution line controls run the machine through two identical operator panels, with the maker's own TMis technological software to ease programming. Bar range depends on the collet: with the automatic magazine, Ø 16 mm to Ø 48 mm for the SK52BZI HAINBUCH collet. Feed length is 180 mm and bars can be 4,000 mm long. The machine is 4,965 mm long without the bar guiding system, 7,811 mm with it, and weighs 11,750 kg.
