The high rigidity and high precision of these spindles guarantees high geometrical accuracy and excellent surface finish. They are especially effective for the internal grinding of deep holes. Our spindles have a compact design and are able to reach high rotation speeds (up to 180’000 rpm) and high power (40kW for 170mm spindle housing diameter). Tool cooling systems and sensors for the fast set-up can be also integrated.
