GEN MILL 5X-4 5 Axis High Speed VMC • 4-

Expand Machinery is now offering the GEN MILL 5X-4, a five-axis milling machine that features:

  • 4-inch zero-backlash roller gear cam tilting rotary table
  • 12,000-rpm inline direct-drive beltless spindle
  • 7.5-hp spindle motor with 6000-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
  • 2,362-ipm rapid rates in X, Y & Z-axis for fast production

According to Expand Machinery, the machine provides exceptionally fast tool indexing. Its cast iron construction is matched by the crossroller bearing way system, reported to be twice as stiff as ball bearing methods to provide improved cutting rigidity and tool life as well as a high degree of positioning accuracy. The Mitsubishi M80 control keeps up with the five-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.


  • Four Types Of Five-Axis Machining Centers

    Different machines offer different approaches to rotary travel, and each design has its own strengths. Here's how they compare.

  • Composites Machining for the F-35

    Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.

  • Machining Micron-Tolerance Micro-Parts Teaches Lasting Lessons

    Different tools and machining strategies have driven this shop to seek new efficiencies beyond its most demanding work and most capable machining center.
