· Z-axis travel length: 200 mm
· Clearance height: 180 mm

The basic frame structure is a monolithic construction made of thick-walled steel. It is reinforced across the entire machine bed with welded triangular plates, making it extremely stable. The use of the triangle shape with a broad base for load-bearing parts is the secret to permanent precision and stability. The layout of the machine allows the operator an optimal workflow while requiring minimal floor space. The resulting frame provides a balanced and secure base for the machining unit with outstanding load distribution.

The mobile aggregate carrier is constructed as a solid monoblock. It is positioned along the X-axis on prismatically ground guides via recirculating ball carriages. The machining unit, in turn, is mounted to the mobile carrier using prismatic, ground rails and recirculating ball carriages.
