New Job Shop Control from Siemens


By Patrick Waurzyniak
Senior Editor

Aiming for the job shop market, CNC developer Siemens Industry Inc., Motion Control Business (Elk Grove Village, IL) introduced its new Sinumerik 808D control for entry-level milling and turning machines.  

With a more affordable price, the new control will target three-axis machine tools, particularly in the Asia market. Designed for highly competitive, high-volume 230-V, three-phase and economy machine tool market, the 808D features up to three-axis plus spindle control capability in milling or turning applications, and is offered as a package with Siemens Sinamics drives and Simotics motor solutions. 

At IMTS, Siemens demonstrated showed the new CNC on a knee mill. Available immediately for OEM machine tool builders and in-the-field retrofit installation by Siemens business partners worldwide, the control is said to be easy to use, featuring the Sinumerik Operate interface, and also very easy to set up.  

Commissioning is made easier with a ready-to-run PLC program. Customizing the PLC is simpler as well, with function and data blocks for program testing and debugging built-in. The Sinumerik 808D further allows easy connection to the PLC I/O of other machine devices, whether proximate or remote, and customized HMI screens and menu trees are easily defined and created.  

“This is as close to plug-and-play as you’re going to get out of the box,” notes Randy Pearson, manager, end-user support, Siemens Industry Inc. 

The control features the embedded Linux operating system, making it stable and free from virus issues, Pearson adds. Among the 808D’s standard features are a 7.5-inch LCD color display with 640x480 resolution, selectable function keyboard, rotary dials for speed and spindle override, LED tool number display, durable buffer battery and rear connection ports for USB, RS232 C, distributed and onboard I/O, setpoint to feed axes and spindle, spindle encoder, and fast I/O for probes and handwheel operation. 

The control also features 80-bit nano floating point accuracy and intelligent jerk limitation for smoother path cutting and less mechanical stress on the machine structures, helping performance whether a machinist is turning with a C-axis changeover or milling mold sections where path control is paramount.
