Turning Center Designed For Small Parts
Miyano Machinery’s GN-3200 ultra-precision turning center features a 0. 1-μm input tolerance.
Miyano Machinery’s GN-3200 ultra-precision turning center features a 0.1-μm input tolerance. It is suited for high-precision hard turning of small components that are traditionally finished on a grinding machine.
The machine is intended primarily for secondary operation finishing work and hard turning of heat-treated components. The center has a maximum turning diameter of 1.77" (45 mm) and maximum turning length of 1.97" (50 mm).
The turning center features a heat-symmetric frame and bed, a wing-type headstock and a separate coolant tank to ensure that thermal distortion will not occur over time and that 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, the company says. Both X-axis and Z-axis slideways are said to provide quality damping performance.
Machine tool builders in Korea have been playing a catch-up game for the past decade. A review of current developments in machine tool technology indicates that Korea is rapidly pulling up with manufacturers in Japan, Europe and the United States. The products from Korea closely match their counterparts from other global suppliers in terms of capability and quality.
Horn USA has developed quick-change tooling systems to drastically reduce set-up and toolchange times for Swiss-type lathes, including those with through coolant.
Turning hardened materials to grinding-like accuracies takes the right combination of part, machine and process parameters.
