The Schneeberger Sirius machine has been designed to meet the exacting demands of grinding very small tools (down to 0.4mm). Tool clamping has been designed so that grinding forces are not exerted on the component: the clamping chucks are fixed axially in the dividing head but are allowed to float radially. Concentricity is ensured with a prismatic steady rest and an additional rest under the grinding zone. Concentricity is better than one micron (0.00004 in). The steady rests are set up with a camera, which includes a ring light that is mounted during the set up procedure. The enlarged picture is displayed on the control monitor.
Loading is automatic with a 6-axis robot. Fully automated, lights out machining can be implemented easily when the machine is equipped with a flexible 2 to18 pallet loader.
Manufactured by Schneeberger, the Sirius has a heavy duty, 9 kWmotor with an HSK80 spindle for wheels up to 300 mm with a speed range of 6,000-1,000 rpm. Control is by the Fanuc 160 iB with 15” TFT colour monitor. Digitally regulated axes provide high speed traversing with smooth continuous interpolation of 5 axes
