Linear motion systems for customized machine tool automation

Upgraded portfolio of ready-to-install linear motion systems for machine tools. Electromechanical cylinder and linear motion axes from Rexroth.

Machine tools place particularly high requirements with regard to the precision and robustness of the linear motion systems used. This is true for both the main axes and the auxiliary axes for loading and unloading workpieces, the tool change and support. With an upgraded linear motion systems portfolio, Rexroth supports application-oriented automation. The linear motion axes and actuators guarantee a high system rigidity and precision with the best possible protection against chips, coolant and other contaminants.

The trend is clear: according to their own information, manufacturers of machine tools currently deliver between 70 and 90 percent of their machines with integrated automation. This is expected to grow further with the increase of networking in production. The tool and workpiece change therefore constitutes a significant focal point. With a wide range of linear motion axes and electromechanical cylinders, Rexroth covers a large spectrum of applications for the most diverse workpiece sizes and weights with travel distances from just a few millimeters to up to 10,000 millimeters.

The Compactmodule CKK/CKR and Linearmodule MKK/MKR have proved versatile as handling axes for tool or workpiece changes. They comprise a ball rail system with high system rigidity and robustness against vibrations. An aluminum body in connection with a sealing strip or a bellows protects the enclosed mechanics from coolants and chips. If the dimensions are identical, the user can choose between ball screw assembly and toothed belt drive to reflect different requirements of dynamics and accuracy. The one-point lubrication feature on two sides facilitates easy maintenance.

Electromechanical cylinders

Manufacturers of machine tools can also use the EMC electromechanical cylinder by Rexroth for feeding and swiveling movements. They combine the flexibility and energy efficiency of electric drive technology and free positioning with the advantages of compact cylinders. Users can freely parameterize force, position and speed and flexibly adapt the values to new tasks at any time. With the newly designed lubrication points, users can integrate the electromechanical cylinders with central lubrication concepts.

From standard to customized special versions

Rexroth delivers entire linear motion systems as a mechanical assembly or as a complete axis with different motors and drive controllers. Rexroth's cooperation with machine tool manufacturers as a system partner spans decades, meaning that Rexroth knows the specific requirements of sealing technology and also develops customer-specific variants of all linear motion systems. For particularly heavy workpiece weights, Rexroth provides customer-specific linear modules with stable steel bodies and has already implemented multi-axis handling systems for weights of up to 300 kg.

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. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 33,700 associates generated sales revenue of approximately 5.6 billion euros in 2014.

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.
