UNIMILL Series Gantry Milling Machine

Extremely rigid cutting with power up to 300 kW.

Categories: , ,

Pietro Carnaghi has produced vertical movable portal milling machines (GANTRY type) named Series UNIMILL for many decades.

Characterized by extremely innovative technical solutions and with a high level of automation and quality, UNIMILL machines are designed and assembled with massive structures, with the movable portal sustained by means of hydrostatic guideways, including the movement of Y-axis. The distance between the columns arrives up to 10000 mm (32.8 ft) and the working plane arrives to 9000 mm (29.5 ft). Floor plate length is modular and it is defined by customer needs. The UNIMILL gantry milling machines can be equipped with an additional turning table, to be the most complete solution for all the possible machining requirements. Unimill machines allow operation with a pendulum concept: it is possible to have 2 separate areas on the floor table. One machining area, with protections and movable enclosures (optional) and one area to set up the part, that is accessible with bridges on the covers of the guideways.

During the design activity, the main focus was on the flexibility, to ensure the maximum productivity. Accessory and tool change is fully automatic, with toolchain, disk magazines or movable pick up systems. A wide range of different accessories for milling operations are available.

With the consolidated experience in a wide range of application fields, and years of cooperation with the more important and experienced manufacturing companies all around the world, Pietro Carnaghi developed, in more than 80 years, the most advanced and reliable accessories.

A brief list of the main accessories:
• Automatic and modular turning toolholders
• Turning toolholders with automatic extensions
• Table with Y-axis and milling head with Y-axis travel
• Second (mirror) carriage
• Grinding accessories

Considering the relevant milling spindle speed (3000 g/1’) and the balance of the masses in the spindle itself, it is possible to have a dedicated accessory for grinding operations.

In order to reach higher rotational speeds grinding electrospindles are available.
• Universal heads
• High-speed milling heads
• Table/pallet with hydraulic automatic jaws
• Magnetic tables
• High-pressure toolholders (up to 750 bar)
• Automatic boring heads with controller axis
