The structure of the base body is a monolithic construction made of thick-walled steel. It is reinforced throughout the machine bed by welded triangular plates, making it extremely stable. The triangular shape used for the supporting parts, with a large base, is the key to long-lasting precision and stability.

The machine's layout allows the user an optimal workflow despite minimal space requirements. The base body, constructed in this way, provides the machining unit with a balanced and secure base with particularly good load distribution. The mobile unit carrier is made from a solid monoblock. It is positioned in the X-direction on prismatically ground guides via ball screw slides. The machining unit is, in turn, attached to the mobile unit carrier on prismatic, ground guides and the ball screw slide.
