----Our outstanding product SINUMERIK 840D is suitable for various control technologies through system settings on complex system platforms. The 840D, along with the SINUMERIK_611 digital drive system and SIMATIC S7 programmable controller, forms a fully digital control system that is suitable for controlling various complex machining tasks and has better dynamic quality and control accuracy than other systems.

----The characteristic of a standard control system is that it has a large number of control functions, such as drilling, turning, milling, grinding, and special control, which do not have any mutual influence during use. Due to its open structure, this complete system is also suitable for other technologies such as shearing, stamping, and laser processing.

----The highlight of SINUMERIK 840D lies in its constantly expanding features.

----The powerful network capabilities of SINUMERIK 840D make it possible for modern management to emerge.

----For example, NC now includes neural networks, whose self-learning and self optimizing systems greatly shorten the adjustment time of the system. Fine tuning can also be performed simply and automatically according to the requirements of machine tool users.

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

----Maximizing integration is our consistent approach. The SINUMERIK 840D is integrated into the same 50mm wide framework as the SIMODRIVE 611 control module, SIMODRIVE 611D， Combined with the advanced SIMATIC S7 system, it provides a comprehensive solution for the automation of machine tools: a fully digital system, innovative system architecture, higher control quality, higher system resolution, and shorter sampling time, ensuring first-class workpiece quality.

SINUMERIK 840D： Standard CNC systems are suitable for almost all applications

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

----For example, a lathe with digital communication between a CNC system and SIMODRIVE can achieve the machining accuracy of a grinder.

Powerful system functionality

----840D can also implement many special NC functions, which are difficult to see in similar systems.
