Multicenter solutions: beyond flexible machining centers and transfer machines

Our new multicenter line of multifunctional solutions for precision component in metals for all manufacturing sectors (automotive, aeronautical, hydraulic, medical, etc.) production represents a unique flexible production approach, surpassing the classic use of multiple machining center lines on one side, and transfer machines with revolver tool turret heads on the other side.

Main characteristics:

The bed is an innovative box type structure that achieves higher rigidity of the system - compared with the open structure used in the traditional construction method used in normal machining centers - and increased vibration damping capability.

Powerful 3 axis modules with 12-20 pocket tool magazines mean that a large quantity of waste material can be removed in all conditions of use.

The system uses satellite tables (*) with continuous 360,000 programmable positioning mounted on a main table that is used for pallet changes.
By using a brushless motor the pallets are changed in only 2.2 s (M-04-03 model). The use of a large diameter Hirth crown in the main table guarantees superior precision and rigidity. It is therefore much quicker than in normal machining centers.
The use of advanced multiple blocking equipment enables several parts, even different ones, to be machined at the same time.

(*): available as a standard version with 2 oil passages for tool management or with 4 oil passages to control more complex tools and increase flexibility.
