Motor spindles Main features series 900 Round spindle housing design Mounting flange Automatic clamping system Modern machining operations require capable and dynamic spindle drives. Our 900 series is a spindle concept that our technicians and engineers developed from customers’ applications in line with market demands. Building on many special versions, the spindle structure has been revised and standardised in order to achieve reasonable price structures. The latest techniques in the areas of bearings, motor and clamping technology, lubrication, sealing, sensor technology and materials were used in the 900 series, enabled through innovative product development and practical engineering. The technology of the 900 series Chuck HSK interfaces with nominal sizes between 63 and 160 are available for the 900 series. A clamping set with integral spring pack is used to clamp the tools. The releasing unit operates hydraulically or pneumatically. The clamping state is controlled via a sensor and indicates 3 positions (released/clamped/clamped without tools). An integral rotary encoder positions the spindle for tool changes. Bearing We only fit high precision preloaded bearings. These have excellent attenuation properties and wearing characteristics. Concentricity, measured at the chuck, is < 0.002 mm. The spindles run as smoothly as they do thanks to their rigid construction and optimised balancing. Rotational direction Spindles can be operated clockwise or CCW. Lubrication Lifetime grease lubrication Motor It is driven by a liquid-cooled, variable induction motor. Power ratings from 20–120 kW are available.
