    CNC technology from the technology leader, paired with a revolutionary operating concept

    Increased productivity in production

    • The SINUMERIK 808D ADVANCED control is a panel-based CNC control. The compact and user-friendly entry-level solution is used for simple turning applications. Features such as simple operation, commissioning and maintenance are the perfect basis for equipping CNC machines.
    • Due to its technology-specific characteristics, the SINUMERIK 808D ADVANCED control is perfectly preconfigured for turning. Due to the hardware and software extensions, the SINUMERIK 808D ADVANCED also offers sufficient performance for simple turning functions for mold and tool making.


    • Thanks to a panel-based CNC design with few interfaces and an operator panel in protection class IP65, the SINUMERIK 808D ADVANCED is perfectly prepared for use in harsh environments. The small dimensions enable the use in compact machines.


    • Control-identical software package for further simplification of the handling of the machine.


    • 8.4” LCD color display with 800 x 600 resolution


    • RJ45 Ethernet port
    • Prepared for remote maintenance
    • AST function; enables simple optimization with higher demands on dynamics and accuracy
    • Absolute encoder/no reference travel necessary
    • Higher accuracy

    Extended warranty

    With the extended warranty you protect your new machine against warranty damage for a further 12 or 36 months (only to be bought with purchase of machine).
