Unfortunately we do not perform retrofits outside of the United States, Canada, and Mexico at this time
Offering maximum CNC performance, as well as a degree of flexibility and opennessthat is absolutely unique in the market, the Siemens SINUMERIK 840D sl CNC is the basis for almostany CNC machine. A powerful hardware architecture and intelligent control algorithms— complemented by outstanding drive and motor technology – ensure machiningwith the highest dynamic performance and precision.
Siemens SINUMERIK 840D CNC offers maximum performance
The SINUMERIK 840D sl offers an almost inexhaustible performance potential — thanks toits drive-based, high-performance NCUs (Numerical Control Units) with state-of-the-artmulti-core processor technology. This means that up to 93 axes in 30 machining channelscan be controlled in the NCU link. Machine tools with fewer axes benefit from theperformance of the SINUMERIK 840D sl as a result of the highest degree of machiningprecision with the shortest machining times.
Demanding turning and milling applications are part of the wide technology spectrum
High-speed milling and turning are two of the strengths of the SINUMERIK 840D sl.The milling spectrum extends from highly productive machining centers for powertrainmanufacturing in the automotive industry, up to high-speed 5-axis machining centers formoldmaking in the aerospace industry. The turning spectrum extends from multi-channel5-axis turning centers with B-axis up to highly productive multi-spindle applications.
Beyond turning and milling applications, the Siemens SINUMERIK 840D sl can address an almostinexhaustible range of technologies ranging from grinding and laser machining, throughgearwheel, up to multi-tasking machining.
The SINUMERIK 840D sl CNC is even the first choice for new engineering and manufacturingapplications including tapelaying and composites for the aerospace industry.
Modular and scalable
In addition to scalable NCU performance, the SINUMERIK 840D sl has a high degree ofmodularity when it comes to the operating components. With flexible M:N operation, forexample, any operator panel can be combined with the NCU making the SINUMERIK 840D slthe ideal fit in the operation of high-end machine tools. With SINUMERIK 840D sl BASIC, thelink with the compact SINAMICS S120 Combi drive, even compact machines can be ideallyaddressed.
SINUMERIK CNC performance –the machining standard
SINUMERIK CNCs and SINAMICS drives compute with high-performance80-bit NANOFP accuracy. This eliminates rounding errors and results in anextremely high internal computational accuracy in the complete controllercircuit. Further, a dynamic feed forward control ensures that the followingerror is almost completely compensated – and jerk limitation reduces stresson the mechanical system when axes accelerate. Using its Dynamic ServoControl, SINAMICS control technology provides additional position controlin the drive – representing an additional advantage by achieving anincreased level of disturbance resistance of the machine control.
When machining many CNC blocks in the shortest time, for example, freeformsurfaces, the machining process itself no longer defines the speed,but the performance of the CNC. Here, with its Advanced Surface and TopSurface features, SINUMERIK offers the ideal solution. Advanced Surfacestands for state-of-the-art control algorithms, such as Look Ahead or thedynamic compression of linear and circular blocks in 5th degree polynomials(NURBS). Machines can be operated at their physical limits whenusing Advanced Surface and Top Surface.
Shortest idle times
Especially in large series production, idle times, where the machine is nolonger productive, represent a critical productivity-inhibiting factor. Here,SINUMERIK provides the optimum solution with its synchronous architectureand intelligent functions, such as synchronized actions and asynchronoussubprograms. For example, loading equipment can be implementedwithout having to make time-consuming changes to the PLC program.
