SCM TECH Z 25

Workspace: 2780 x 1140 mm (vertical milling), 2500 x 950 mm (horizontal drilling). Travel X-Y: 2980 x 1271 mm. Z-axis travel: 200 mm. Clearance height: 180 mm. The base structure is a monolithic design made of thick-walled steel, reinforced throughout the entire machine bed by fully welded triangular plates, resulting in extreme rigidity. The triangle shape with a wide base, used for all load-bearing components, is the secret to ensuring lasting precision and stability. The machine layout provides the operator with an optimal workflow while requiring minimal space. This base structure offers the machining unit a balanced and secure foundation with outstanding load distribution.

The mobile aggregate support is constructed as a solid monoblock. It travels along the X-axis on precision-ground linear guides by means of recirculating ball bearing carriages. The machining unit is mounted to the mobile support via precision-ground linear guides and ball bearing carriages as well.
