SINUMERIK 840D

SINUMERIK 840D digital NC system for complex machining

Our outstanding product, the SINUMERIK 840D, is suitable for various control technologies through system settings on complex system platforms. Together with the SINUMERIK_611 digital drive system and the SIMATIC©7 programmable controller, the 840D forms an all-digital control system that is suitable for the control of complex machining tasks with superior dynamic quality and control accuracy over other systems.

The standard control system features a large number of control functions such as drilling, turning, milling, grinding and special controls that do not interact with each other during use. Due to the open structure, this complete system is also suitable for other technologies such as shearing, stamping and laser machining.

The outstanding feature of the SINUMERIK 840D is its ever-expanding nature.

The powerful network capabilities of the SINUMERIK 840D make it possible to modernize management.

For example, NC now includes a neural network, and its self-learning, self-optimizing system greatly reduces the system's adjustment time. Fine adjustments can also be made simply and automatically as required by the machine user.

In addition to the SINUMERIK 840D and SIMODRIVE 611, an easy-to-use profiling digital system can be generated with minimal hardware and software investment.

The integration of the SINUMERIK 840D is the same as the SIMODRIVE 611 control module. The SINUMERIK 840D, SIMODRIVE 611D and the advanced SIMATIC S7 system provide a comprehensive range of automation for the machine. The solution: a fully digital system, an innovative system structure, higher control quality, higher system resolution and shorter sampling times ensure first-class workpiece quality.

SINUMERIK 840D: standard CNC system for almost all applications

It uses the most advanced control concepts available today for control of drilling, milling and turning and grinding machine tools.

For example, a lathe with digital communication between the numerical control system and SIMODRIVE can achieve the machining accuracy of the grinding machine.

Powerful system features

The 840D also implements many special NC functions that are difficult to see in similar systems.

SINUMERIK 840Di

Today, modern control systems based on industrial PCs are increasingly being used in automation engineering. Coupled with standard operating systems, such as Windows NT, these control systems are playing an increasingly important role in open and flexible hardware and software platforms. In the familiar PC world, users can be said to be well-versed.

The fully PC-integrated SINUMERIK 840Di CNC system offers you a new PC-based control concept. The main benefits of this concept are those where PCs are used in some way or self-control schemes using distributed drivers and I/O. Applications include wood products, glass, ceramics, packaging, placement machines, punching machines, bending machines, and machines for a variety of machine tools and similar machine tools. In addition to the high degree of software and hardware openness, the distinguishing feature of the SINUMERIK 840Di is that the CNC control and control functions are run on the PC processor together with the HMI function. That is to say, the NC processing unit required in the conventional control system can be omitted. This control system consists of a large number of standardized components: industrial PC with interface card, PROFIBUS-DP, Windows NT operating system, OPC (OLE for Process Control) interface and NC control software.

A lot more is available for SINUMERIK 840Di. Particularly advantageous is its position in the SINUMERIK family. For example, the NC and PLC functions of the SINUMERIK 840D and SINUMERIK 840Di are compatible with the operator functions and machine data. The corresponding NC program and PLC program can be run on both systems. And because the system is highly open, software applications are equally applicable to both systems. The SINUMERIK 840Di is part of the SIMATIC and SIMODRIVE automation control environment.

Step-by-step configuration with PROFIBUS-DP. The trend of the system towards a distributed direction is now very obvious. Another important feature of the SINUMERIK 840Di is the PROFIBUS-DP with position control. This is a unified fieldbus for drive and I/O. It allows for a distributed configuration of the system.

The SIMATIC ProTool/Pro configuration tool plus the attached "SINUMERIK ProTool/Pro option" offers you special convenience. That is, users can use it to generate their own dedicated user interface without having to master additional software engineering skills.

All features are grouped together in the same module for optimal communication. The MCI board is a PCI-type board. The module contains the integrated SIMATIC S7 315-2 DP PLC-CPU and for MPI (multi-interface) and PROFIBUS DP interface and I/O. The SIMODRIVE 611 universal drive unit can be connected. The SIMATIC DP ET200 module is available as an I/O.
