Single place and two place milling-turning centres. Available as single-spindle and double-spindle TWIN. Ideal for stable and precise complete milling and turning of complex workpieces.

Integrated workpiece handling, defined loading positions and predefined interfaces for easy automation with various loading and unloading systems.

With the ability to mill and turn a vast range of workpiece sizes and geometries, STAMA System MT 8 and MT 8 TWIN machining centres lead to significant cost and time savings.

One controller for all chip removal technologies: Milling, drilling and turning operations can be combined in any order for an economically and technically optimal machining process.

Large rotary indexing tables and device bridges with torque technology in the A-axis, along with strong turning spindles in the B-axis, enable stable and precise (simultaneous) 5-axis machining – milled, drilled and turned.
