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
