CNC sliding head lathes

SR-38 type A / B

THE ADVANTAGES

In comparison to its proven smaller brother the SR-20R IV, the new SR-38 type A/B automatic CNC sliding headstock lathe has an extended material capability of 38 mm. Furthermore, balance cut machining can be carried out on the tool post (X3 axis). The swivel B axis offers additional machining possibilities.

  • FANUC 31i-B5 control system (SR-38 type A: 31i-B)
  • Movable control panel
  • C axis control as standard on main and sub spindle
  • Convertible from sliding headstock to fixed headstock lathe
  • B axis for the front and rear side on the tool post
  • Additional X3 axis for simultaneous turning on the front side
  • Fully independent backworking with 8 stations (all power-driven)

KINEMATICS & TOOLS

  • 7 turning tools
  • Each with 5 drilling tools (front and rear side)
  • 9 + α power-driven tools on the tool post
  • 11 + α power-driven tools for backworking
  • 9 axes type A / 10 axes type B
