MEGA SSS-400/600 5AXP (5-AXIS)

The high-accuracy, high-precision fusion of 5 axis technology for your micro-fine milling and small-hole drilling needs

When the job calls for high-precision cutting, you use a 5-axis milling machine. But sometimes there are other factors to consider, and not all 5-axis milling machines are created equal. For some projects—the kind that require fast, accurate results down to the 1,000th of a millimeter—you need a machine that’s up to the task.

The MEGA SSS family of 5-axis machining centers combine high-speed machining (40,000 and 60,000 RPM via the 400 and 600 versions, respectively) with micro-fine detailing capabilities, allowing your shop to reliably tackle small-hole drilling, micro-accuracy machining, and more.

Come see what a difference a true hybrid milling machine can make—for your customers, your shop, and you.


  • By delivering high-accuracy cuts quickly, the MEGA SSS-400/600 5AXP makes you more productive, allowing you greater control over your business.


  • The MEGA SSS-400/600 5AXP combines rugged construction materials and dynamic internal components to enable continuous operation at max speed—without compromising quality.


  • By offering multiple milling capabilities all in one single machine, the MEGA SSS-400/600 5AXP lets you handle more than ever before—backed up by best-in-class support from our responsive service teams.


  • Ideal for both small-hole drilling and micro-fine 5-axis milling through its unique “super hybrid” design
  • Allows simultaneous 5-axis control with a special design for optical encoder feedback on the rotary unit
  • Wide speed range (3,000 through 40,000 RPM for the 400), (3,000 through 60,000 RPM for the 600) via an oil-mist lubricated spindle and a long-life AC motor
  • Capable of 5-second tool changes, thanks to 20-position twin arm-style tool changer
  • Provides both high-precision 3-axis positioning and additional 2-axis indexing accuracy
  • Operates across a wide speed range via an oil-mist lubricated spindle and a long-life AC motor
  • Provides excellent shock and vibration dampening for high-speed, high-precision machining and greater stability via high-rigidity structure and Meehanite GC castings for both the base and bridge
  • Built to jig-grinder standards of quality and accuracy with bridge construction that eliminates the X axis table overhang commonly associated with C-frame construction designs
  • New tool measurement device location “Blum Laser” is relocated to an out-of-stroke position
  • A pneumatic counterbalance is located on the spindle headstock providing smooth, accurate movement of the Z axis during high-velocity contouring and drilling
  • Features an increased portal height (7.9”/200mm) for addition of the A/C axis unit


  • High-rigidity Meehanite structure
  • High-rigidity HSK-E40 tool holders, allowing 6x higher clamping force than a regular BT shank for highly reliable work
  • Roller pack-type linear motion ways
  • Z axis thermal growth compensation
  • Non-contact tool measurement (Blum Laser) with air-blow cleaning
  • Dual Z axis balance cylinders
  • X, Y, Z axis linear scales
  • Spindle chiller with 7-gallon oil tank
  • 80-gallon coolant tank standard


  • Fanuc 31i-B5 super high-speed processing, NANO smoothing, AI Contour Control II, and NANO interpolation
  • 1000-block look-ahead block expansion
  • Super PC III function with 3-mode operation to balance speed and accuracy
