Performance boost for CNC hardware in the high-end segment


EMO 2015 – Hall 3, Booth E06/F03

  • New powerful CPUs and panels for Sinumerik 840D sl
  • Shorter program runtimes, faster simulation
  • Larger memory and lower power consumption

In the course of introducing version 4.7 of the Sinumerik Operate software, Siemens is presenting new, more powerful CPUs, and 15 and 19 inch "Blackline" panels in widescreen format for the Sinumerik 840D sl CNC. The new 7x0.3B PN processors are Profinet-compatible NCUs (Numerical Control Units). The new processor technology, for example the NCU 730.3B PN, is up to 15 percent more powerful than the previously used components. The result is shorter program runtimes, faster simulation, and fast operation in all situations. The new technology, exemplified by the 720.3B PN and 730.3B PN NCUs, also consumes up to 50 percent less power which, in turn, causes the processors to generate less heat.

The basic configurations of the 7x0.3B PN-CPUs for the Sinumerik 840D sl already have 10 MB of buffered user memory as standard for part programs, and a 2 GB working memory (DRAM). The part program memory can be expanded up to 22 MB, depending on the particular processor model. In most cases, automatic adaptation of the drivers enables the new NCUs to be integrated into existing machines and applications without modifying the software. The new, long-term availability of the new NCU processor technology offers a secure future for newly developed machines – both for their subsequent further development and on account of the long-term availability of spare part components.

The new 15 and 19 inch "Blackline" panels are widescreen format touch screens. They are mainly characterized by good legibility, simple operation and a long service life. The technical basis of the display is a capacitive sensor system that supports touch operation even when gloves are worn. The panels are designed for degree of protection IP66 and are especially rugged. For example, the 15 inch panel is approved for vibration accelerations up to 2 g. Both the new devices have an integrated thin client unit (TCU) and are connected to the Sinumerik via Ethernet.


The new NCUs and panels expand the Siemens range of CNC systems and products. By using the new hardware components, companies can increase both the performance and the ease of operation of their machines.
