Expand Machinery’s Genmill 5X-4 Offers Rigid Base Design

Expand Machinery’s Genmill 5X-4 is a 5-axis, high-speed VMC designed to provide manufacturers with a fast, compact and affordable 5-axis solution. The company says this milling machine provides fast tool indexing and rapid rates for increased productivity.

The cast iron construction is said to be matched by a cross-roller bearing way system that is twice as stiff as ball bearing ways to provide cutting rigidity and improved tool life as well as positioning accuracy. The Mitsubishi M80 control keeps up with the 5-axis moves with a 135,000 block per minute processing speed and a 1,350-block look-ahead. It also features Nano smoothing and a 32 GB solid-state data server.

Other features include a 4" zero-backlash, roller gear, cam-tilting rotary table; 12,000 rpm, inline direct-drive beltless spindle; 7.5-hp spindle motor with 6,000 rpm synchronous rigid tapping; BT #30 BBT dual contact “big-plus” spindle; 21-tool drum turret with 1.6-second tool-to-tool tool change time; and 2,362 ipm rapid rates in X, Y and Z axis for fast production.
