A world first at the EuroBLECH 2016: the modularly expandable punching machine from TRUMPF is a milestone of their successful development work with Bosch Rexroth

  • The new kinematics revolutionizes entry-level punching machines
  • Expandable: the pioneering drive and control concept allows for retrofitting of the laser function
  • All from a single source: control, drive, energy management and safety software from the Bosch Rexroth modular system

At EuroBLECH 2016, TRUMPF Werkzeugmaschinen will set a new standard for entry-level punching machines. At the heart of the new TruPunch 1000: The modular control and regulation concept, co-developed with Bosch Rexroth, allows for gradual expansion to a combined punch/laser machine and therefore allows the machine to "grow" based on the user’s requirements. Thanks to its innovative kinematics and safety solution, the TruPunch 1000 and the TruMatic 1000 fiber combination machine demonstrate standout performance in space requirements, functionality and efficiency. Cost-efficient parts handling and a significantly reduced installation area are just a few of the highlights. As a supplier with a comprehensive product offering and capability set, Bosch Rexroth delivers all of the control and drive components and supports TRUMPF in engineering and worldwide service.

The newly developed modular punching kinematics – called Delta Drive – is the most recent milestone in the development partnership between the two companies that has existed for over ten years. The special feature of the new machine generation: the punching head and die move only in one direction, the sheet is also moved orthogonally in only one direction. This new concept not only reduces the installation area, but also the effort for parts handling. This way, the machines can optionally and cost-efficiently adopt completely new functions themselves, such as sorting or targeted storage, without an additional system.

"The cooperation with Bosch Rexroth as a developmental and system partner has proven itself for many years," explains Stefan Kerscher, head of new development design / punching combination machines at TRUMPF Werkzeugmaschinen GmbH. "The modular drive and control concept opens up completely new options for us when it comes to engineering." For the new machine kinematics, Bosch Rexroth supported TRUMPF with a modal analysis and also assisted in developing a software-based safety concept, including the function "safe cam" at the tool center point for laser safety. In addition to the six real axes, two virtual axes are also continuously monitored.

The drive and control of all axes is accomplished with the help of the powerful CNC platform IndraMotion MTX. The decentralized drive solution, IndraMotion MLD, calculates the transformation of the kinematics. With this foundation, the new machines achieve a cutting gap of up to 0.05 mm at the highest level of performance.

A further result of the developmental cooperation is the pioneering energy concept of the new machine class. For this, the regenerative IndraDrive M – HMV-R eco supply was collaboratively further developed and complemented with capacitive intermediate storage. The IndraWorks engineering framework, which TRUMPF uses for all programming and parameterization work, saves time during engineering and commissioning. In addition, Bosch Rexroth provides support with configuration, commissioning and service around the world.

Visitors can find the TruPunch 1000 and the TruMatic 1000 fiber at the TRUMPF booth in hall 11, stand B48 at the EuroBLECH 2016 from October 25 to 29.

Valuable data from the machine tool

Both the users and manufacturers of machine tools are very keen to collect sufficient machine data in order to visualize and optimize the manufacturing processes and plant efficiency. The subsequent analysis of this data will reduce unplanned downtimes and lead to more efficient production with smaller batch sizes. With the IoT Gateway, Rexroth provides an easy to configure solution to collect sensor and machine data from existing, even older machinery and transfer it to higher-level IT systems. In terms of investment protection, this does not require any interference in the existing automation infrastructure.


The factory of the future creates added value through flexibility and agility

In future production environments demands on adaptability will rise. This development can only be realized by separating hardware and software in automation. Bosch Rexroth AG promotes this development primarily with a broad product spectrum from sensors to drive and control technology to software solutions.
