Horizontal boring mill MAF-C series


Evolved in Every Aspect, the Future is in this New Model

Movie Movie List


Whole Cast Structure Realizes Superb Rigidity

  • High-rigidity is achieved through wholly cast-finished major structures and hydrostatic bearings employed for guide surfaces for all axes.
  • Full-power 55-kW machining is possible at the Y-axis height of 2500 mm.
  • 4-face hydrostatic bearing constraint achieves high-rigidity of the compact □420 mm ram.

Highest Cutting Speed in its Class

  • Rapid traverse speed of 15 m/min (Z and W axes) and 20 m/min (X and Y axes) are the highest speed in its class
  • Spindle speed of 2500 min-1 is the highest in its class
  • ATC time and AAC time are reduced more than 50% compared to conventional models to 25 sec. and 60 sec., respectively.

A New Balancing Mechanism Enables More Accurate Cutting

Replacing the conventional perfect balance mechanism which uses counter-balancing method, is our new balance mechanism in which our unique column tension bar is adopted to achieve cutting with higher accuracy.

User Friendly Refinements Abound

  • Employed □420-mm RAM improves the machine's accessibility.
  • Our unique machining support software (5-face machining, simplified aligning) is further enriched and helps operators create machining programs.
  • Lubrication unit and other maintenance equipment are concentrated around the column workbench to reduce workload in daily maintenance.

A Wide Variety of Attachments and Layouts Mean Optimum Machining

We offer optimum machine layout (i.e. combined use with rotary table) plans as well as a wide variety of attachments that satisfy customers’ complex machining needs.
