Miyano Releases New GN-3200 Ultra-Precision Turning Center

Miyano Machinery has introduced the new GN-3200 Ultra-Precision Turning Center. With a 0.1 µm (four millionths) input tolerance, the GN-3200 is designed for high-precision hard turning of small components that are traditionally finished on a grinding machine.

"The GN-3200 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," said a spokesperson. "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.

"The GN-3200 has a maximum turning diameter of 45 mm (1.77-inch) and maximum turning length of 50 mm (1.97-inch). Unmanned operation is possible using the standard high-speed gantry loader with a maximum service time of 3.5 seconds. All of these high performance functions and more are packed into the highly compact GN-3200 that occupies a floor space of only 2.3ft wide by 4.8ft deep."
