The GN4200 Autoloaded CNC is the latest space-saving, high-precision CNC lathe in the Miyano GN series. Engineered for efficient machining of small-diameter workpieces, it features a rigid wing-type fixed spindle mounted on a thermally symmetrical bed to minimize heat distortion. This advanced structure supports consistent dimensional and roundness accuracy even over long production runs.
Built-in spindle cooling and low-vibration beltless drives further enhanced consistency and surface finish.
Built on Citizen’s “high-precision design concept,” the GN-4200 integrates precision scraped slideways with exceptional damping characteristics, hand-finished by expert craftsmen to ensure stability and accuracy at every stage of the machining process.
While capable of manual operation, the GN-4200 also supports a full range of automation options, including high-speed gantry loaders, robot integration, and flexible infeed/outfeed systems. This makes it ideal for manufacturers looking to increase throughput while maintaining tight tolerances.
