AKB-11 / AKB-13

CNC Horizontal Boring & Milling Machines


FEATURES

  • The column traverse allows for heavy-duty workpieces and improves accessibility to the workpiece.
  • Standard coil type chip conveyor provides parallel to the X-axis capable of effective swarf disposal and cutting fluid disposal.
  • AKB series employs Japanese technology with Japanese quality and reliability, but produced at lower cost than made-in-Japan products.
  • High-accuracy indexing ensures standard rotary milling.
  • Powerful heavy-duty cutting is capable by a high-torque 2-steps geared head.
  • Standard Big-Plus dual contact system.
