AS Series Single Column Design (6500 mm – 18000 mm)

This structure is very functional for large diameter turning operations, having a huge capacity to increase the working diameter.

Category:

Pietro Carnaghi vertical turning centers model AS is designed in an extremely rigid structure with a single column. This structure is very functional for large diameter turning operations, having a huge capacity to increase the working diameter.

The AS model structure is composed of one base where the spindle and table gearbox are located, one column structure with slideways for movable crossrail and table base (as optional feature it can be translating type). These elements are assembled to form a rigid frame, ensuring maximum stability and strength.

A sophisticated mechanism of the Crossrail and column mechanical compensation has been developed in years of experience in different fields: from nuclear parts machining to aerospace components.

Three different types of compensation rods work together in order to minimize geometric deflections, resulting from the movement of large mass units on the machine axis. In addition, machine structures are designed with the finite element analysis methodology (FEM) and the mainframes are subjected to thermal stabilization and treatment processes.

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
