ANCA MX7

The ANCA MX7 is a linear motor tool grinder on a bi-symmetrical gantry, with a 38 kW (51 HP) peak, 20 kW (27 HP) S1 spindle on an HSK 50F taper. The table calls it productive up to Ø 25 mm (1”) with a maximum tool length of 300 mm (12”), a full size class above the FX7.

Power is the first thing that separates it. The S1 rating alone, 20 kW, is higher than the 19 kW (25.5 HP) peak of the FX7, and the 38 kW peak is twice that FX7 figure. The continuous rating is what carries deep flutes in a 25 mm carbide blank, where the wheel stays engaged for the whole pass.

Axis travel is 540 mm in X, 510 mm in Y and 217 mm in Z. The A axis turns a full 360°, while the C axis has 264° of travel, listed as +44 and -220. C is not continuous, so wheel approach angles have to be planned inside that window.

Wheel capacity involves a choice. The table lists 2 wheel packs of up to Ø 203 mm (8”) or 6 packs of up to Ø 152 mm (6”), on a 6-station wheel changer with a maximum wheel pack weight of 8 kg. Running six packs therefore means giving up the largest wheel diameter.

Two loaders are listed, both as options. FastLoad-MX holds 245 x Ø 3 mm, 156 x Ø 6 mm or 42 x Ø 16 mm, and its figures stop at Ø 16 mm. RoboMate holds 2520 x Ø 3 mm, 1560 x Ø 6 mm, 462 x Ø 16 mm or 189 x Ø 25 mm, and it is the only one with a capacity given at the machine's full Ø 25 mm. The footprint is 2246 mm (88”) W x 1856 mm (73”) D x 2116 mm (83”) H, and the control is the ANCA AMC5 G2 High Performance CNC with Windows 10.
