Circular Seating Machine KRM Series

Special-purpose machine for efficient machining of large-diameter circular seating surfaces.

  • This is a specially designed machine tool that enables efficiency and low-cost machining of large-diameter swivel base sections of large workpieces such as construction machinery.
  • High-precision NC machining in all axes.
  • Adopts a highly reliable FANUC controller.
  • High torque and high horsepower for excellent cutting performance.

High work efficiency and excellent cost performance.

Circular seating surface can be efficiently machined by placing directly on the workpiece. By replacing the cutting tool, "hole," "tap," and "seat face" machining is possible.
