Siemens expands Sinumerik 828 controllers family

Siemens has expanded the functional scope of its Sinumerik 828 family of controllers with new hardware and software. The compact CNC controllers are now equipped with the new software version 4.7 and the powerful PPU 2xx.3.

The new Sinumerik 828D Advanced has the ability to control up to 10 axes/spindles as well as two auxiliary axes. In addition, the most powerful Sinumerik 828 offers a second machining channel for simultaneous machining with two tools.

The further development of the compact Sinumerik 828 controllers offers users above all higher productivity and improved performance of their machine tools. Sinumerik 828D Advanced is capable of controlling milling machines with up to eight interpolating axes or spindles and two additional auxiliary axes for the control of tool chains, pallet changers, chip conveyors or other peripheral devices. Users can also use a second machining channel to execute two different NC programs simultaneously in their turning and rotary grinding machines, or they can synchronise the programmes with each other extremely simply using ProgramSync. In this way, two work pieces can be machined at the same time in one machine, for example for simultaneous rear face machining in the counterspindle.

With the new software version 4.7, the G-Tech software is available to Sinumerik 828 controllers for grinding applications. It supports machine manufacturers in designing compact grinding machines with up to ten axes and two machining channels. In addition, the Sinumerik 828 offers grinding machine manufacturers functionalities such as grinding cycles and tailor-made tool management.

Siemens has also made the creation of parts programs on the Sinumerik 828 more efficient and faster. One such improvement is the ability to transfer contour elements directly from a DXF file via contour detection into the programming of workpiece machining. A host of different documents and file formats can be called up directly on the screen of the Sinumerik for support.

Sinumerik 828 V4.7 also offers comprehensive protection of cycle know-how, which prevents unauthorised access to sequences preprogrammed in the factory. Custom-made user interfaces can use new programming elements, such as dialog windows to indicate progress and concealed password entry, which make the implementation especially user-friendly. The CNC Lock option offers manufacturers protection when supplying machines on an installment basis. After activation of the option, the machine initially runs for a limited time only, and can then be commissioned fully via a code following full payment by the user.
