CITIZEN M32 V CNC sliding head lathe

CITIZEN M32 V CNC sliding head lathe was built in 2003 in Japan by CITIZEN WATCH CO., LTD. The machine is used for precision 8-axis machining of workpieces of even the most complex geometries. All machining processes, i.e. precise drilling, threading and turning are performed by 2 reliable spindles and tools taken from 3 capacious tool stations. What’s more, the specially designed bed with high thermal stability perfectly reduces the influence of heat, increasing the service life of all components and cutting tools.

The offer also includes a wide range of equipment that significantly extends the machine’s machining capabilities and guarantees excellent repeatability of the manufactured parts. This includes e.g. an advanced CNC controller with many useful functions, such as self-diagnosis and program backup. All this makes the CITIZEN M32V swiss-type lathe the best choice for many industries such as the automotive or aerospace industry. The M32 V CNC automatic lathe weighs 3200 kg.
