Twin-Spindle CNC Chucker Cuts Production Time
Muratec USA, a subsidiary of Murata Machinery, offers the MW120GT twin-spindle CNC chucker.
Designed for complex turning applications, the machine features two automated three-axis gantry loaders and can accommodate chucks measuring 165 or 210 mm (6.496" and 8.268") in diameter. Separating and isolating the machine bed and enclosures from the machine structure is said to eliminate harmonic vibration transfer. A high-speed gantry loader and turret axes reduce cycle time. The machine features automated loading and unloading gantry systems and can integrate into virtually any manufacturing environment.
As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
Turning hardened materials to grinding-like accuracies takes the right combination of part, machine and process parameters.
UNCC researchers introduce modulation into the tool path. Chip breaking was the goal, but higher metal removal rate is an intriguing secondary effect.
