Sinumerik 828D Basic for milling and turning machines in the mid-range job shop market
Siemens expanded offerings with additional versions of its popular, compact CNC for the job shop, the Sinumerik 828D. Siemens Sinumerik 828D Basic T (turning) and Basic M (milling) CNCs enhance job shop performance in all segments of this market, the company said.
Siemens Sinumerik 828D BASIC T is designed to address the needs of shop floor 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, for face and peripheral surfacing, are possible. In tandem with the new Sinamics S120 Combi drives package, the 828D Basic T represents a new level of efficiency and virtually maintenance-free operation, as the fans, hard disks, and batteries of past CNC generations have been eliminated.
With a rugged die-cast magnesium front panel on an IP65 enclosure, the Basic T enables an Ethernet connection, USB, or Compact Flash (CF) card program loading. Standard features include an 8.4-in. color display for easy readability and simple QWERTY keyboard that provides fast ramp-up for the operator. Various communication ports in USB, Ethernet, Drive-CLiQ, PLC I/O interface, RS232 C, and NC inputs/outputs are available.
In operation, reliable 80-bit nano accuracy means contour control precision and a better workpiece, every time, 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.
Siemens Sinumerik 828D Basic M class features the same quality performance as the T class, but 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 T will operate a milling machine at the highest level of performance possible. Superior axis and spindle dynamics within a broad speed bandwidth yield quality workpieces, every time, the company said.
All the other benefits of the Siemens CNC family, including the Sinumerik Operate graphical user interface platform as well as ShopMill and ShopTurn easy programming, are offered in these new 828D CNCs.
Siemens Sinumerik 828D is capable of full graphical, high-level language command and supports ISO programming that is customary in the United States.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
