HMC with Large Work Envelope



Okuma America Corporation has launched the Okuma MA-600HIII HMC, which brings next-level machining capabilities to the MA-600H family by offering several new features.

The MA-600HIII's new 10K RPM standard spindle handles a wide range of applications, from heavy-duty to high-feed machining. The enhanced spindle is now equipped with a new through-spindle coolant suction feature, which removes residual coolant inside the tool and spindle.

This next-generation HMC weighs in at 55,000 lbs., providing structural stability and consistent precision machining operations for the long haul, according to the company. This machine has a larger work envelope than its predecessor with added X-axis travel capabilities. The MA-600HIII can perform automatic tool change operations in less than four seconds.

Additional enhancements have been made to Okuma's thermal management technology, including decreased temperature deviation of the machine to an improved 7 µ dimensional change per 24-hour period. This is particularly effective when faced with severe swings in the ambient temperature, the company noted.

The Okuma MA-600HIII features an enhanced coolant management system, ball screw cooling for the X, Y and Z axes, an upgraded workspace design to prevent chip accumulation and improved chip evacuation functionality. These contribute to maximized uptime and allow for long periods of continuous machine operation.

The all-new sludgeless tank technology activates sophisticated filtering and liquid flow patterns of the chip/coolant mixture to mitigate settling of the mixture in the bottom of the receiving tank. This new technology reduces the need for time-consuming tank cleaning and affords increased machine operation time.

The MA-600HIII's flexible design allows for a variety of automation applications. The workspace area can equip up to seven part loading/unloading ports or up to eight workholding clamp ports, which can help eliminate the need for complicated circuit arrangements for hydraulic applications. Up to 16 ports are available in the machine's set-up station, expanding part capacity and the possibilities for robotic applications.

Key specs of the MA-600HIII:

  • Table size: 24.8" x 24.8"
  • Max. loadable size: 41.34" x 47.24"
  • Spindle speed: 10,000 RPM (6,000, 12,000, 15,000 and 20,000 options available)
  • Weight: 55,000 lbs.
  • Rapid traverse XYZ: 2,362 IPM, 2,362 IPM, 2,362 IPM.
