Siemens Introduces Entry-Level CNC for Milling & Turning Applications

Siemens Industry's new Sinumerik 808D Advanced CNC is designed for basic milling and turning machines. Affordably priced for the OEM, this new addition offers a suite of design features to improve the accuracy, surface finish, safety, and communication of the control, the company said in a press release sent to Design News.

The Sinumerik 808D Advanced offers up to five axes/spindle motion controls on a single machine channel, with drive bus communication between the CNC and drive for better position control, data transfer over standard Ethernet protocol, Auto Servo Tuning (AST) for superior surface quality, and repeatable part accuracy in mold and die applications. These include an incremental encoder with 2,500 parts per revolution or an absolute encoder with 20-bit resolution.

Motor speeds up to 4,000 rpm are offered with Safe Torque Off (STO) and IP65 enclosure protection. Vertical and horizontal configurations of the Sinumerik 808D are available to suit all standard control panels. The Sinumerik 808D Advanced T is the ideal choice for basic turning machines or turning centers without a Y-axis, with the option of driven tools. The Sinumerik 808D Advanced M offers advanced surface finish and the SINAMICS V70 drive platform from Siemens. All have an attractive price-to-performance ratio.

Additional features of the Sinumerik 808D Advanced CNC include: an RJ45 Ethernet port, a 7.5-inch LCD color display with a 640 x 480 resolution for easy viewing, machine-technology-specific keyboards with hard keys shielded with protective membrane, a robust enclosure with no fan or hard disk, maintenance-friendly power with no battery, continuous data buffering with NV-RAM technology; an LED tool number display; and a master control panel with rotary switch for feed and spindle override. The rated torque is 1.9-40 Nm with drive line input of 400V and overload rating of 300 percent.

Part programs can be managed on an external PC, then fed to the control over an Ethernet cable, or input via the USB port. Simple program sub-folders can be stored on the control, just like on a PC. Other standard features of the Siemens CNC for machine operators and programmers include intelligent jog, precise tool data handling with easy-to-recognize on-screen icons, tool wear data logging to ensure consistent high workpiece quality, and startGUIDE engineering support, complete with a graphical user interface wizard for easier machine commissioning and startup and troubleshooting.
