Siemens offers its newest solution for the job shop floor, the Sinumerik 808D CNC for entry-level milling and turning machines and the 828D Basic T and M for milling and turning machines.
This control, was specially designed for the high-volume 230V, three-phase and economy machine tool market. With up to three-axis plus spindle control capability in milling or turning applications, the 808D is offered as a package with Siemens Sinamics drives and Simotics motor solutions.
Machine tool builders can start with an IP 65 enclosure, easy-to-load USB port, mechanical, hot and soft keys for intuitive operation, clamp-mounted front panel and a modular design that allows customizing by machine model or with out-of-the-box operation. Plus, the machine control panel is connected using plug-and-play technology utilizing a USB interface. "On a turning machine, the Sinumerik 808D provides high contour accuracy and maximum machine productivity for high-volume production runs. On a milling machine, likewise, the Sinumerik 808D offers machine builders of vertical machining centers all the benefits of the Siemens MDynamics velocity control for mold and die work," said a company spokesperson.
A 7.5-inch LCD color display with 640 x 480 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, fast I/O, e.g., for probes and handwheel operation are all standard on the Sinumerik 808D.
With 80-bit nano floating point accuracy and intelligent jerk limitation for smoother path cutting and less mechanical stress on the machine structures, workpiece accuracy and repeatability are improved.
With programGuide Basic, a wide range of pre-determined technology cycles is available, 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.
For routine or even online help with maintenance or troubleshooting issues, a simple push of a button is the only requirement, as the complete library of system parameters is accessible onscreen.
"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. The open architecture of Siemens CNC has not been sacrificed on the 808D, so customized HMI screens and menu trees are easily defined and created," said a company spokesperson.
Finally, 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.
"For end-users, in addition to the above features and benefits for the machine builder, shop operators and programmers alike will appreciate the Sinumerik 808D for its many 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. An operator can access all system information and obtain online help, whenever needed," said the spokesperson.
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.
Sinumerik 828D Basic T and M for Milling and Turning Machines
Siemens now offers new versions of its 828D, compact CNC for mid-range job shops. The Sinumerik 828D BASIC T (turning) and BASIC M (milling) CNCs are designed for job shops in all segments of this market.
The Sinumerik 828D BASIC T is designed to address the needs of shopfloor turning machines. It combines CNC, PLC, operator panel and axis control for five axes/spindles, including live tooling. Milling and drilling operations on a turning machine, both for face and peripheral surfacing, are therefore possible. In tandem with the new Sinamics S120 Combi drives package, the 828D BASIC T is designed for maintenance-free operation, as the fans, hard disks and batteries of past CNC generations have been eliminated.
With rugged diecast magnesium front panel on an IP65 enclosure, the BASIC T enables an Ethernet connection, USB or Compact Flash (CF) card program loading. The 8.4-inch color display has a simple QWERTY keyboard. Various communication ports in USB, Ethernet, Drive-CLiQ, PLC I/O interface, RS232 C and NC inputs/outputs are standard.
In operation, 80-bit nano accuracy means precision contour control, while Siemens intelligent kinematic transformations provide the proper orientation of machining plane to work surface.
Though simple command language is provided for operator ease, the BASIC T functions with the highest level of ISO programming language. Established cutting cycles can be utilized with fully Animated Elements for the faster visualization of part production on various levels with combinations of Sinumerik CNC and ISO programming languages possible, as well.
The Sinumerik 828D BASIC M class is for use on milling machines. "Even in complex moldmaking operations, mirror-smooth surfacing and reduced machining times are enabled. Again, in tandem with the Sinamics S120 Combi drives package and Simotics feed and spindle motors, the 828D BASIC M is designed with superior axis and spindle dynamics within a broad speed bandwith to produce quality workpieces," said the spokesperson.
The Sinumerik 828D is capable of full graphical, high-level language command and supports ISO programming that is customary in the United States. This control family is suited for single-part and small-batch production. Programming time can be further reduced for small-batch production with the use of the ShopMill and ShopTurn graphical workstep programming systems, while high-level language programming can be used in conjunction with programGuide to significantly reduce programming times for large-scale serial production.
Also included with the Sinumerik 828D family of CNC, modern PC and mobile phone technology are also available for the mid-range machine tool. Online help animations and a new type of input prompting system with moving picture sequences provide the basis for user assistance. USB, Compact Flash (CF) card and Ethernet ports enable high-speed data transfers onto storage media or integration of the control system into corporate data networks.
Through the use of its Easy Message functionality, the Sinumerik 828D family offers production status monitoring by text messaging (SMS). Depending on the recipient's profile settings, the machine tool can transmit information about workpiece machining status, report on the tool condition currently in use and send machine maintenance bulletins to a mobile phone.
