- 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
