GILDEMEISTER TWIN 65 CNC automatic lathe

GILDEMEISTER TWIN 65 CNC automatic lathe was built in 2005 in Germany by GILDEMEISTER Drehmaschinen GmbH. The machine is used for precise, multi-axis machining of workpieces with complex geometries. To increase overall production efficiency, a combination of two spindles and two 12-position turrets with excellent technical specifications are used inside the large working area. Both spindles feature a C-axis with a high indexing accuracy of ± 0.002 mm, which facilitates complex machining operations that require precise positioning of the workpiece. All this is complemented by an intelligent SIEMENS CNC control with an intuitive interface. The GILDEMEISTER CNC turning center weighs 10000 kg.
