Miyano BNE-51MSY

Fixed headstock type automatic CNC lathe

  • Nine cutting axes (X1, Z1, Y1, X2, Z2, X3, Z3, C1, C2)
  • Two spindles
  • Two 12 station turrets
  • One Y-axis slide
  • 25-Nm twenty-four revolving tool stations
  • 2" diameter bar capacity

Additional Details

The MSY model extends the ability of the BNE series through the implementation of the X3 axis on the back spindle and synchronized/superimposed control for 3-tool simultaneous machining, resulting in faster cycle times, ease of use, and the ability to machine complex work pieces.

The user-friendly Mitsubishi M720VS control incorporates useful screens for programming assistance including easy-to-view edit screens, machining data screens, calculation functions and more.
