 HIGH-SPEED APPLICATIONS 

HIGH-SPEED SPINDLES IN MACHINE TOOLS

High-speed spindles in machine tools require a high rotating field frequency and allow only low excess temperatures due to the small rotor volume. Our frequency converters are able to generate these frequencies and guarantee a low heating of the motors by means of special control technologies.

Whether for machine tools in the size of a single-family house or for small CAD/CAM milling machines with limited space, SIEB & MEYER has the right solution.

The converter in question is suitable for sensorless as well as for sensor-controlled operation of synchronous and asynchronous motors up to a speed of 120,000 min-1. The parameterization can be easily realized via the software drivemaster2.

  • Drilling, Routing

    High-speed spindles are the key components of a machine tool. Only when operated in an optimal way, the desired machining accuracy, productivity and service life of the whole machine is guaranteed. 

     

  • Grinding

    Grinding applications have a special position in the field of machine tools. Internal grinding applications, for example, require sensorless operation of asynchronous and synchronous spindles up to 250,000 rpm. 

     

  • Dressing

    For dressing applications, it is essential to keep the spindle temperature low: a temperature increase in the spindle causes a longitudinal growth and therefore a shift of the tool position. 

     

  • Dental CAD/CAM

    Small CAD/CAM routing machines are used, for example, in dental laboratories for jewelry making or engraving works as well as for producing advertising displays. 

     

  • Wafer Dicing

    High-speed dicing spindles are the key components in machines for microchip separation – the so-called wafer dicing. 

     

  • Wastewater Treatment

    Due to their design, a large number of technologies in the field of waste energy usage or mechanical energy storage require high-speed motors and generators

     

  • Atomizer

    Rotary atomization processes, e.g. applied for the production of milk powder or flue gas treatment, require high circumferential speeds. Therefore, it is necessary to use matching high-speed motors instead of low-speed standard motors.

     

  • Polygon Scanners

    Polygon scanners are based on special optics and operate, for example, sorting machines. Up to now, manufacturers had to install encoders to run these scanners with a high speed stability.
