Description

Pietro Carnaghi vertical turning centers model AS are 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 gear box 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 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 elements analysis methodology (FEM) and the main frames are subjected to thermal stabilization and treatment processes.
