EMCO Mecof Powermill G3 PC3: robust structure without compromising on agility
Although the Powermill G3 PC3 was designed by Mecof to meet the needs of customers with limited space but a strong focus on large-scale production, this machine leaves nothing to chance and is in no way inferior to its larger counterparts. Built for an Italian customer involved in general mechanics, this machine stands out for its ability to combine structural robustness and compactness while ensuring a large working area, high performance and Industry 4.0 digital solutions.

Equipped with Heidenhain TNC 640 HSCI numerical control and Heidenhain's Industry 4.0 package, the Powermill G3 PC3 makes integration with the digital world one of its strengths.
Compact but capable
With axis strokes of X = 8,000 mm, Y = 4,500 mm and Z = 1,500 mm, the Powermill G3 PC3 is ideal for machining large components. The 8,000 x 3,000 mm work surface, with a load capacity of up to 15,000kg/m² (class II DIN 876), ensures maximum stability even during the most demanding operations.
The heart of the machine is the universal bi-rotary head with automatic millesimal positioning, 38 kW power, maximum torque of 615 Nm and speeds of up to 6,000 rpm, with ISO 50 tool attachment. This combination allows for a wide range of machining operations, from heavy roughing to high-precision finishing.
The picture is completed by a 60-position chain tool changer, a chip evacuation system, a cooling system and advanced solutions for the latest generation of tool and workpiece control. Specifically, the tool changer is fixed to the crossbeam shoulder. This system, combined with the sliding exchange arm, ensures speed and reliability in tool replacement operations, optimising cycle times. Chip evacuation with longitudinally arranged ramp conveyors is quick and smooth. The cooling system, with dual delivery
(near the spindle and through the spindle), ensures tool efficiency and longevity, supported by a multi- stage filtration system up to 25 µm. At the customer's request, this system is served by a collection tank and a filtering tank, each with a capacity of 1000 litres. Filtering degree: 1) 60 µm and 2) 30 µm, carried out by means of cartridge filters positioned on the filtering tank.
Mecof's Powermill G3 PC3 is not only a high-performance gantry milling machine, but a true intelligent production centre. Thanks to its combination of power, precision and digital connectivity, it is a strategic choice for companies wishing to increase productivity and competitiveness by investing in a Made in Italy machine that embodies the engineering tradition and innovative capacity typical of our country.
