Mill Offers Enhanced Productivity



"Expand Machinery's GEN MILL-4024 combines strength with speed for optimum productivity," said a company spokesperson. It features travels of 40.5" in X, 23.6" in Y and 25.6" in the Z-axis. The Meehanite processed cast iron frame is engineered to provide a high-strength cutting platform with high vibration dampening and efficient metal removal rates.

The 12,000 RPM 25 HP direct-drive in-line #40 taper spindle features rigid tapping and includes a thermostatically controlled spindle-oil cooler. The dual-contact precision ground BIG-PLUS spindle is designed to provide enhanced rigidity, concentricity, tool life, cutting capability and 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 while the 1,417 IPM rapid rates make for reduced cycle times," said the spokesperson. A fast 1.7 second tool-to-tool change time is combined with a 30-tool twin-arm automatic tool changer. An included 300 PSI through-the-tool coolant system is also included for more efficient chip removal and extended tool life. "A variety of helpful standard features that others charge extra for are included with the machine," said the spokesperson.

The Mitsubishi M830 control features High-Speed Machining and includes Super Smooth Surface Control to provide enhanced surface finish. The control processes 270,000 blocks-per-minute with 2,700 block look-ahead by using a high-efficiency, high-speed 64-bit fiber optic backplane and an advanced RISC processer designed exclusively for CNC machine tool use. Mid-program restart capability is another standard feature along with a 32 GB solid-state data server, providing ample part program storage.

"The combination of the high-speed machining features in the M830 CNC control and the enhanced metalcutting attributes of the high-performance BIG-PLUS spindle and other listed enhanced machine characteristics combine to create a more productive metal removal environment," said the spokesperson. "Soderberg Manufacturing, in Walnut, CA, experienced a cycle time reduction from 40 minutes to 14 minutes when they switched an aerospace job to their GEN MILL-4024 and witnessed more efficient chip removal utilizing the volume milling features this machine provides as standard features."

Expand Machinery offers the GEN MILL CNC line-up of vertical milling machines starting at 24" x 16" and going up to 100" in X and 39" in Y in nine sizes. Auto power shut-off and 4th and 5th axis prewire are all standard features with the entire Expand Machinery VMC machine series.

Expand Machinery also produces CNC Swiss machines and multitasking CNC lathes with 3/4" to 3" bar capacity. Expand Machinery has extensive capabilities in production analysis, automation and turn-key solutions in support of challenging production applications.
