BNJ42/51
Fixed Headstock Type CNC Automatic Lathe

Miyano BNJ42/51

  • Processing overlap control with main spindle processing combined with separate sub-spindle movement
  • Eccentric collet enables complex machining of cranks and other eccentric processing
  • It makes easy side milling through the Y-axis function of main turret, thus enables machining of large-diameter screws and/or uneven parts that was impossible to conduct by conventional machines
