CITIZEN M32 V CNC sliding head lathe

CITIZEN M32 V CNC sliding head lathe was built in 2006 in Japan by CITIZEN MACHINERY CO., LTD. The machine, designed for precision machining of workpieces with complex geometries, is distinguished by the use of a number of state-of-the-art solutions aimed at increasing overall production efficiency. These include among others two reliable spindles with C axis and capacious tool stations. What’s more, a specially designed bed with high thermal stability perfectly reduces the impact of heat, increasing the service life of all components and tools. All this is complemented by an intelligent MITSUBISHI CNC control with many useful functions. The CITIZEN M32V swiss-type lathe weighs 3200 kg.
