Precision par excellence EMO 2017 : Magnescale

Magnescale is at EMO Hannover 2017 to showcase its Smartscale SQ47/SQ57 length measurement system with Drive-Cliq interface from Siemens. Thanks to IP67 protection, it is ideal for high-precision positioning on machine tools.

If you have anything to do with metalworking, and particularly machine tools, you'll know just how tight the tolerance ranges are. To achieve such impressive levels of precision, not only do machine tools need to be designed with the utmost care and diligence, they also need to have appropriate measuring systems. For their part, these systems must produce precise measurements at all times, even under sometimes very difficult circumstances, otherwise all that attention to detail in the design phase is for nothing. Japan-based Magnescale Corporation is at EMO Hannover 2017 to exhibit a new generation of absolute length measurement systems that incorporate the Drive-Cliq interface from Siemens.

A year after being launched with Fanuc and Mitsubishi interfaces, the Smartscale SQ47/SQ57 range of absolute length measurement systems is now being extended to include models for machine tools fitted with 840D-SL control systems from Siemens. The combination of newly developed magnetic scale material and TMR sensor technology enables excellent precision of plus/minus three micrometers per meter. Thanks to this precision, a travel speed of three meters per second and a resolution down to five nanometers, the Smartscale SQ47/SQ57 is a real alternative to optical measurement systems. Due to its design, the system is resistant to soiling with oil, water and dust, which according to Magnescale makes the IP67-compliant measuring system perfect for high-precision positioning tasks on machine tools.
