Expand Machinery’s Genmill VMC Provides High-Strength Cutting Platform

Expand Machinery’s Genmill - 4024 VMC combines strength with speed for high productivity, and features travels of 40.5" in X, 23.6" in Y and 25.6" in the Z-axis. The rigidity of the Meehanite processed cast iron frame provides a high-strength cutting platform with superior vibration damping and efficient metal removal rates. The 12,000-rpm, 25-hp direct-drive inline #40 taper spindle features rigid tapping and includes a thermostatically controlled spindle oil cooler.

The company says the dual-contact precision ground “Big-Plus” spindle provides enhanced rigidity, superior concentricity, increased tool life and greater cutting capability as well as excellent tool length repeatability. The machine uses precision, pretensioned roller bearing guideways to provide nearly twice the rigidity of ball bearing ways for enhanced cutting performance and the 1,417 ipm rapid rates make for reduced cycle times. A 1.7-second tool-to-tool change time is combined with a 30-tool, twin-arm automatic tool changer. An included 300-psi through-tool coolant system is also included for more efficient chip removal and extended tool life. The Genmill VMC lineup starts at 24" × 16" and goes up to 100" in X and 39" in Y in nine sizes.
