How much does the Tajmac-ZPS MCG820i cost?
Price estimate
We do not have a price for the Tajmac-ZPS MCG820i that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
Two work tables under one gantry: the MCG820i stretches the Y axis of the ZPS small gantry to 1,800 mm (70.9 in) and puts a 1,200 × 2,000 mm clamping surface beneath it, made up of two fixed tables. X is 1,000 mm and Z is 600 mm.
The maker describes the arrangement as two separate removable tables, or one fixed and one rotary table, in a common or divided working space. Read that as three ways to use the machine. With the space divided, one side can be loaded while the other is cut. With the space common, a single long mould or plate spans both tables. With a fixed table on one side and the optional two-axis rotary table on the other, three-axis and five-axis jobs share one machine without re-rigging. Each fixed table is rated at 3,000 kg/m2.
Because the travelling parts are the same as on the MCG810i, the performance figures carry over: 40 m/min rapids and feedrate, 5 m/s2, a positioning error of 0.008 mm. So do the electrospindles, ISO-40 at 15,000 rpm, HSK-A63 at 18,000 rpm, HSK-A100 at 14,000 rpm and the HSK-T100 turning spindle at 12,000 rpm, and the optional CyTec two-axis head with its ±115° tilt.
Tool handling is different. Where the MCG810i has a 30-tool drum, this model comes with a rack-type tool changer for 50 tools, expandable to 130. The rack takes tools up to 110 mm in diameter, 8 kg in HSK63 and 15 kg in HSK100, but a change takes 8 s, so it favours long cuts over frequent swaps.
The machine weighs 14,500 kg without optional equipment and its clamping surface is 800 mm above the floor. Standard equipment includes chip conveyors with an integrated coolant tank and a fully enclosed work zone.

Frequently Asked Questions
01
Travels are 1,000 mm in X, 1,800 mm in Y and 600 mm in Z. The fixed clamping plate is 1,200 × 2,000 mm, formed by two fixed work tables, with a maximal load given as 3,000 + 3,000 kg/m2. The spindle nose stands 150 - 750 mm above the fixed table.
02
The maker's description is of a vertical milling centre of upper gantry type with two separate removable tables, or one fixed and one rotary table, in a common or divided working space. That allows one table to be set up while the other is in the cut, or both to carry one long part.
03
A rack-type tool changer with a capacity of 50 tools is standard on the MCG820i, and 130 tools are optional. Tool diameter is 110 mm, or 160 mm without adjacent tools; weight is 8 kg for HSK63 and 15 kg for HSK100. Tool change time is 8 s.
04
The MCG810i has 800 mm of Y travel, a single 1,200 × 1,000 mm table and weighs 11,500 kg. The MCG820i has 1,800 mm of Y, twice the clamping surface, and weighs 14,500 kg. X, Z, feeds, accuracy and the spindle list are common to both.
05
A two-axis CNC head with A ±115° and C ±200°, and a two-axis rotary table of Ø 600 or Ø 800 mm with A ±95° and C 360°. The rotary table carries 650 kg at ±15° of tilt. A turning option for the rotary table with an HSK-T100 spindle is also listed.
