For the field of profiling cutting, there is a growing demand to increase productivity and shorten set-up times and CNC interpolation time. The Bosch Rexroth MTX CNC system provides the perfect basis for machine builders and users to meet the growing challenges and at the same time meets the requirements of the OPC UA standard Industry 4.0 communication functions and prepares them for the digitalization of the plant. MTX in combination with ctrlX AUTOMATION system solutions (e.g. the compact ctrlX DRIVE drive) inevitably creates a high-performance system.
Technologically leading manufacturers of CNC laser and plasma cutting systems can significantly reduce machine development time and start the market earlier than expected. This is all thanks to the ready-made MTX CNC system for project templates, as it can provide high-performance features for laser machining, such as high control, flying cuts or frog jumps. As a result, the engineering time, costs and expenses required for any commissioning are reduced.
There is no fastest, only faster – MTX
Machine builders in the field of analog cutting have the same task: to produce fast, accurate and reliable machines. The combination of a high-performance multi-core processor and decentralized, intelligent drive technology makes MTX the most powerful CNC system on the market, enabling extremely high cutting speeds, accelerations and precision. The combination of high-performance control and driver hardware reduces the interpolation time by 0.25 milliseconds. In any application, the MTX highly dynamic machining tasks are guaranteed to be completed with maximum productivity.
Extensible MTX CNC based on an open standards-based platform. With an integrated PLC, a range of different requirements can be met. Bosch Rexroth customers can apply this solution to typical applications in the field of analog cutting, such as 2D laser processing, plasma cutting or waterjet cutting. In cooperation with companies around the world, Bosch Rexroth has developed high-performance motion and technical functions that are specifically tailored to profiling.
The high-performance CNC system and the corresponding drive functions enable users to cut sheet metal patterns 10 to 15 percent faster than before.
Whether it's analog cutting, combined laser/step punching machines, multi-technology systems or bending units, only one control system can be used for a wide range of applications. A wide range of integrated, high-performance technical functions, such as laser power control or height adjustment, reduce costs without the need for additional hardware. The modular design of the software and hardware makes it easier to integrate the system into different machine concepts.
CNC systems and compact drives: two solutions, almost limitless possibilities
Thanks to the comprehensive openness of the Bosch Rexroth solution, users are using the MTX CNC system with almost unlimited combination options. Bosch Rexroth offers a wide range of decentralised intelligent servo drives, highly dynamic rotary servo and linear motors, as well as linear guides with integrated absolute value measurement systems. The MTX CNC system works seamlessly with products in the ctrlX AUTOMATION automation system.
For example, the MTX can be perfectly matched with the world's most compact modular drive system, ctrlX DRIVE, which minimizes automation and installation space. ctrlX DRIVE also meets energy-saving requirements. In addition, the solution can be scaled without destroying the structure.
The system solution, consisting of MTX and ctrlX DRIVE, performs well in terms of openness and scalability. Using only the engineering tools IndraWorks can greatly simplify the engineering process. Bosch Rexroth wants all users to increase the speed of engineering. As a result, MTX and ctrlX DRIVE can be used for virtual commissioning solutions or digital twin simulations, significantly reducing the effort required for engineering and commissioning.
MTX, combined with the solutions of the ctrlX AUTOMATION product family, helps companies of all kinds, including profiling machine builders, meet all their future needs. They are ready to adapt to the changing market and digital needs with the latest developments in the ctrlX AUTOMATION series.

Rexroth variable piston pump displacement control mode
1. Guiding ideology:
1. The pressure depends on the load oil pump, and the output pressure is inversely proportional to the flow rate. In the state of electronic control, when the external load increases, the system pressure increases, when the system pressure increases, the pressure of the front pump oil flow and the rear pump oil flow into the rear pump increases, and the computer detects the ...

Rexroth Relief Valve - How does the relief valve adjust the pressure?
1. Constant pressure overflow: In the throttling adjustment system of the quantitative pump, the fixed pump provides a constant flow rate.
2. When the system pressure increases, the flow demand decreases.
3. At this time, the safety valve is opened, so that the excess flow is returned to the oil tank to ensure the inlet pressure of the safety valve.
