More Information
  • SINUMERIK 808D ADVANCE -- the perfect solution for modern standard machines
  • In combination with a new generation of spindle and axis drives, the SINUMERIK 808D ADVANCE with 8.4" LCD provides an innovative ready-to-use digital CNC solution for modern standard machines
  • This is topped by a guaranteed superior price/performance ratio
  • CNC and drive communicate via a high-speed bus to ensure efficient positioning control plus high precision and optimum cutting performance
  • This globally leading CNC technology provides high performance and power for the control of standard lathes

Advantages - Digital solution provides higher precision:

  • Increased overload capacity supports a faster acceleration and deceleration of machine tools
  • Constant cutting speeds result in an increased surface quality of the workpiece

Increased ruggedness:

  • The SINAMICS features a wide voltage range to prevent machine shut-downs during poor voltage supply conditions. This will significantly reduce machine down-times.
  • During heavy machining operations, an automatic spindle torque adjustment will help protect machining tools and spindle systems.

Increased operator comfort:

  • A fast Ethernet connection facilitates easy start-up and diagnostics of machine tools and simplifies NC program use
