World premiere of innovation from Schweinfurt

Jens Kurzidim of Bosch Rexroth in Schweinfurt is happy about the ball rail guiding wagon celebrating its world premiere starting on September 16th in Hanover.

Bosch Rexroth sets new state of the art for precise machine movements

An innovation from Schweinfurt celebrates its world premiere starting on September 16th at the largest exposition for machine tools, the EMO in Hannover. The new ball rail guiding wagons High Precision (RSHP) by Rexroth ensure that machine tools process metal parts even more precisely and fulfill increased quality requirements.

The machine tool processes a crankshaft for an automotive engine. During that process, the grinding head dynamically dives into the metal crankshaft. A mixture of cooling lubricant and metal cuttings is injected wildly through the machine. During this work step, automotive manufacturers require a precision of a few 1,000ths of a millimeter. For comparison: A human hair is 20 times thicker. The more precise the production of engine parts, the more economical the later engines will be and the longer they will last.

“Machine tools are now absolutely high-tech machines, packed with electronics. In the front of the processed work piece, such as the crankshaft, however, it is still the performance of the mechanics that matters”, Jens Kurzidim of Bosch Rexroth in Schweinfurt emphasizes. For the ball rail systems available on the market thus far, during the procedure under the heavy load of the processing force, which can amount to several kilonewtons, a pulsation often occurs in the area the size of micrometers. For a long time, this was not a problem, but it is not sufficient anymore today in fulfilling the increased quality and precision requirements of the customers.

This, however, is not the case with the new solution from Schweinfurt. “Our developers found the causes of this minute pulsation with the most modern simulation technology and designed the so-called inlet zone of the guiding wagons completely anew”, Kurzidim explains. Moreover, the linear motion technology specialists used the newest insights of raw material technology and tested the prototypes under the harshest conditions. “With this new product, we have taken a quantum leap in mechanics.”

The new ball rail guiding wagons were developed at Bosch Rexroth on Ernst-Sachs-Strasse in Schweinfurt. In light of the world premiere at the EMO in Hanover, Schweinfurt is thus also excited. Jens Kurzidim: “Of course, we are curious how our customers will receive this novelty. The first conversations with machinery manufacturers and machine operators, however, show that we are the first ones to fulfill an important requirement for a key component within the machine tool here.”

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, Factory Automation, and Renewable Energies to develop innovative components as well as tailored system solutions and services.

IMS-A position measuring system now with DRIVE-CLiQ interface

Plug in, determine the measurement section and that's it: Bosch Rexroth makes it even easier to set up the new IMS-A measuring system integrated into linear guides using the additional DRIVE-CLiQ* interface. This Ethernet-based interface recognizes the electronic nameplate of the highly accurate and robust new absolute value measuring system. Since the system's introduction on the market, it has been possible to set it up within a matter of minutes in conjunction with HIPERFACE** and the Rexroth drives IndraDrive. Supplemented by the SSI interface, IMS-A now provides holistic support for universal implementation in machine tools, additive production processes and other applications requiring high levels of precision.
