    Since it was established in 1947, Swiss-based company Meyrat has gained an international reputation as a manufacturer of top-quality motorized and belt-driven spindles. The company is at EMO Hannover 2017 to exhibit a range of new spindles for applications in measuring technology and quality assurance, starting with the compact MHF-16 high-frequency spindle, which boasts a speed of 80,000 rpm. The spindle is the company’s response to the growing popularity of increasingly compact machine tools. At just 80 millimeters long, the MHF-19 is the shortest spindle on the market at present. It is available with axial, radial or frontal connections and in two lengths, thus ensuring compatibility with all current production equipment.

    The Meyrat stand in Hannover is also showcasing dressing spindles with a significantly improved performance capability. The new range features air cooling and high torque at low speeds thanks to innovative synchronous motor technology. Even just changing the motor technology is claimed to increase spindle rigidity by at least 30 percent. What's more, an optional sensor for acoustic emissions can be incorporated to ensure handling and the dressing process run much more efficiently. The sensor is extremely sensitive and picks up the slightest variations in tone when the dresser is in contact with the grinding wheel. Depending on the data acquisition device selected, it is possible to measure the spectrum at different frequencies and then directly optimize the dressing cycles according to actual conditions.
