Tajmac-ZPS MCV2080i

Longest of the ZPS C-frame verticals, the MCV2080i moves its table 2,100 mm (82.7 in) in X. The table measures 2,200 × 780 mm (86.6 × 30.7 in) and carries 3,000 kg (6,614 lb), the highest table load in the MCV line. Y and Z are each 840 mm.

A long, moving table raises two practical questions. First, the footprint: the floor plan without chip conveyor is 4,830 × 2,477 mm, and the table needs room to travel beyond it at both ends of X. Second, loading: 3,000 kg spread along 2,200 mm suits beams, rails, long plates and several vises in a row better than one compact heavy block. The table has five 18 mm T-slots at a 160 mm pitch, including a calibrated central slot.

Mechanically it is the MCV1680i with a longer base axis. It shares that machine's 30 m/min rapid traverse, 3.5 m/s2 acceleration and 0.009 mm positioning error, and weighs 14,600 kg, where the MCV1680i weighs 13,800 kg. The same spindle units are offered: gearbox spindles from 10,000 rpm in ISO 40 down to a 3,500 rpm ISO 50 unit with 893 / 1,339 Nm, a 12,000 rpm belt-driven unit, and electrospindles at 15,000 rpm, 18,000 rpm and 14,000 rpm.

Two options change how the length is used. A one- or two-axis CNC rotary table can be fitted, and the brochure notes that a fourth axis can be connected into the automatic pallet change. The pallet changer itself works with 2,200 x 780 mm pallets loaded to 1,500 kg and exchanges them in 30 s, with 720 mm of Z travel remaining.

Standard accessories include chip conveyors, telescopic cover wash-out, automatic central lubrication and electronic compensation of thermal dilatations. Control is Heidenhain, Sinumerik or Fanuc.
