Modig IM-8

The Modig IM-8 is a single-spindle 5-axis machining center that Modig lists with an inverted orientation, built around an 800 mm (31 in) diameter A/C trunnion table and linear travels of 1,000 x 1,000 x 800 mm (39 x 39 x 31 in). A 4-axis X/Y/Z/A version is offered as an option. The table carries 850 kg (1,874 lbs), and the part can be 700 mm (28 in) high within a maximum interference diameter of 1,200 mm (47 in).

The A-axis covers 300 degrees, which Modig writes as +/-120 +60, and the C-axis turns 360 degrees continuously. Continuous C rotation is what a turning operation needs, and mill-turn is on the list at 1,200 rpm, so round features can be turned in the same clamping as the milled ones. It is an option, not part of the base machine.

The standard spindle runs to 24,000 rpm with 50 kW (68 hp) S1 and 95 Nm (70 ft-lbs) S1 through an HSK-A63 interface. With 95 Nm at the tool, the base machine is set up for high-speed cutting with small and medium tools, which suits aluminum and composite better than heavy roughing in steel or titanium. The options change the picture: 30,000 rpm, 150 kW (201 hp) and 550 Nm (406 ft-lbs) are each listed, together with HSK-A100 (SK40/50, BT40/50). The table does not say which of those optional figures belong to the same spindle, so ask for the speed, power and torque of one specific spindle before matching it to the work.

The magazine holds 60 tools as standard and up to 300 as an option, with a chip-to-chip time of 6 sec. A tool can be 200 mm (8 in) in diameter and weigh 10 kg (22 lbs). Tool length is 400 mm (16 in) on the standard machine and up to 650 mm (26 in) as an option. Z travel is 800 mm (31 in) and the part can be 700 mm (28 in) tall; tool length and part height both draw on that stroke, so check reach and clearance on tall work. Modig names cast iron, die casting, aluminum, titanium, composite and steel as materials.
