Dental CAD/CAM

The optimal products for your dental CAD/CAM application

Small CAD/CAM routing machines are used, for example, in dental laboratories for jewelery making or engraving works as well as for producing advertising displays. The very compact dimensions of these machines leave little space for built-in electronic components.

Frequency converters by SIEB & MEYER stand out for their compact design and for keeping the motor heating low even at maximum power. This is beneficial especially for the sensitive bearings of the spindles but also for the machining quality.

Since safety technology is playing an increasingly important role even for the operation of such small machines, the frequency converters by SIEB & MEYER provide the safety function STO as standard.

  • Frequency Converter SD4S

    Ready for the Future

    Complex tasks are quickly processed with the frequency converter SD4S. The devices are designed for stationary use in control cabinets of machine tools, turbo compressors and turbo blowers.

  • Frequency Converter SD4B

    The Space Marvel

    Frequency converter SD4B by SIEB & MEYER, the successor of SD2B plus, can be used as a highly dynamic servo amplifier for the operation of rotary and linear low-voltage servo motors as well as for optimized operation of high-speed low-voltage synchronous and asynchronous motors and of IPM motors.
