Portal Milling Machine in table design for 5-side machining
The ASCAMILL series was developed in close co-operation with the University of Magdeburg for application in production where the utmost is demanded of the machining centers. Efficiency, precision and operator convenience and, not least, ease of service, characterize this new generation of portal milling machines.
Column, connection part and cross rail are manufactured of quality casting. The cross rail is adjustable without steps.
The new table design is developed on bionic cognition and manufactured as special honeycomb structure. So it’s highly inherently stable and nevertheless weight optimized. The table feed in X-direction as well as the support saddle representing the Y-axis is driven by servomotor, gears and double pinion/rack and therewith guarantees maximum stiffness and accuracy. The drives of the linear axes X and Y are electronically preloaded.
The ram is made of cast design GGG 60 and the ram housing of cast design GGG 40. Another highlight the C-axis integrated into the ram can be positioned step less.
The proven Masterhead Principle allows a flexible and technology oriented application of several machining heads. The automatic tool changing system with chain magazine is vertically mounted on the left hand column of the machine and can be loaded / unloaded during the machining process.
The CNC control Sinumerik 840D sl is easy to operate. The machine is equipped with up to date energy efficient servo drives. Direct absolute measuring systems obviate any need of reference runs. All CNC axes are based on centrally lubricated linear guideway systems.
