Flat bed CNC Lathe

LC Series

Heavy duty model

  • Solid box-construction casting headstock
  • Spindle speed ranges are auto changed by M code
  • Infinitely variable speeds are commanded by S code
  • Three (3) “V” bed ways for better rigidity
  • Full power output at low spindle speed
  • High torque (166 times of spindle motor torque)
