The GN-3200 ultra-precision turning center from Miyano Machinery has a 0.1 micrometer (4 millionths) input tolerance and is especially useful for high-precision hard turning of small components that are traditionally finished on a grinding machine.

Able to achieve tolerances historically associated with grinding operations, Miyano’s GN Series machines are primarily intended for second operation finishing work and hard turning of heat treated components. The turning center has a maximum turning diameter of 45 mm (1.77”) and maximum turning length of 50 mm (1.97”).

The machine features a heat-symmetric machine frame and bed, wing-type headstock and separate coolant tank so that thermal distortion will not occur over time and heat generated by machining will not be transmitted to the machine body. The single slide structure of the X-axis turret and the Z-axis spindle achieves almost zero lost motion by improving follow-up accuracy. Both X-axis and Z-axis slideways, hand scraped by highly skilled engineers, have superior damping performance, and this, coupled with a precisely controlled discharge of slideway lubricant, ensures the machine’s ability to perform heavy-duty, high-precision turning.

Designed for out-of-the-box automation, all GN Series machines feature a standard high-speed gantry loader with a maximum service time of 3.5 seconds. The compact GN-3200 occupies a floor space of only 2.3 ft. wide × 4.8 ft. deep.
