AC Series (1600 mm – 3200 mm)

The Pietro Carnaghi AC Series Single frame design offers high rigidity and power in a small frame.

Category:
  • The Pietro Carnaghi vertical turning centre model AC is designed and built in a compact form, with an extremely rigid thermo symmetrical structure, having the column-mounted to the table base.
  • All these elements are assembled together in order to constitute a tough structure ensuring maximum stability and rigidity.
  • The movable crossrail is designed and sized to withstand severe cutting conditions.
  • On the front part, two horizontal sliding guides support the vertical ram saddle in its horizontal movement (through hydrostatic pockets).
  • The distance between the superior and the inferior guideway is dimensioned to ensure the maximum cutting performances.

The different available configurations (different turning height, ram sections, machining accessories, measuring probes accessories) make the models AC to be the more flexible and useful to any need: starting from the most sophisticated precision in finishing operations (parts for aeronautics), to the most severe cutting conditions (forging rings).

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
