IMTS 2012: New CNC for Entry-Level Mill/Turn

Customized by model, and with out-of-the-box operation 7.5-inch LCD display, 640 x 480 resolution programGuide Basic makes available a range of pre-determined technology cycles

Siemens Drive Technologies Division this week is introducing Sinumerik 808D, the latest addition to its series of CNC drives, and priced as an entry-level control for milling and turning machines.  Siemens Drive Technologies supplies electrical and mechanical components products, systems, applications, solutions and services for the entire drive train.  The introduction was timed for this week’s International Manufacturing Technology Show (IMTS).

The Sinumerik 808D is designed for the 230-V, three-phase and economy machine tool market, a competitive and high-volume segment of manufacturing.  With up to three-axis plus spindle control capability in milling or turning applications, it is offered as a package with Siemens Sinamics drives and Simotics motor solutions. 

The Sinumerik 808D will be immediately available for OEM machine tool builders and for retrofit installation at current operations by Siemens business partners, worldwide. 

The advantages for machine tool builders start with an IP 65 enclosure, easy-to-load USB port, mechanical, hot and soft keys for easy, intuitive operation, clamp-mounted front panel and a modular design that allows customizing by machine model or with out-of-the-box operation. 

In addition, the machine control panel is a plug-and-play installation using a simple USB interface.  On a turning machine, the Sinumerik 808D provides high-contour accuracy and maximum machine productivity on high-volume production runs.  On a milling machine, it offers builders of vertical machining centers all the benefits of the Siemens MDynamics velocity control for mold-and-die section work. 

A 7.5-inch LCD color display with 640 x 480 resolution for easy reading, 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, fast I/O, e.g., for probes and handwheel operation are all standard on the Sinumerik 808D.  

Workpiece accuracy and repeatability are improved because of the drives’ 80-bit, “nano floating point” accuracy and intelligent jerk limitation that support smoother path cutting and less mechanical stress on the machine structures.  Whether turning with a C-axis changeover or milling mold sections where path control is paramount, the Sinumerik 808D is designed to significant heighten the performance level of basic machine tools. 

The new CNC features programGuide Basic, making available a range of pre-determined technology cycles, in addition to the standard G-code and coordinate transformation language.  Standard ISO codes can also be intermixed with high-level Sinumerik CNC commands on the 808D.   The onboard contour computer further allows complex programs to be created and modified at the CNC without the need for a CAD/CAM system. 

A full library of system parameters is accessible onscreen at the push of a button, so maintenance or troubleshooting issues are readily addressed.

Commissioning is simplified with a ready-to-run PLC program that is customizable with built-in function and data blocks for program testing and debugging. 

The Sinumerik 808D further easy connection to the PLC I/O of other machine devices, whether proximate or remote. The Siemens CNC open architecture remains available, so customized HMI screens and menu trees are easy to define and create.

Last, with Manual Machine Plus (MM+) function on this new CNC enables transition from conventional machining to CNC programming.  A machine equipped with MM+ can be operated using handwheels but with all the benefits of CNC-assisted technology cycles. 

In addition to the above features and benefits for the machine builder, shop operators and programmers alike will appreciate the Sinumerik 808D for its end-user advantages, including simplified keyboard entry of all program values, named part programs in subfolders just like a PC, convenient shortcut keys to access tool offset lists or the Program Manager, intelligent jog features easily identified and graphically-supported, precise tool handling and tool wear data readily available onscreen and a powerful simulation routine. 

The multimedia training materials include on-screen tutorial video and full step-by-step procedures to go from the blueprint to the finished part.  For offline training, a fully operable software machine control panel on a PC is available to end users.
