Motor spindles
Main features series 910
Rectangular spindle housing design
Manual clamping system
Modern machining operations require capable and dynamic spindle drives.
Our 910 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 910 series, enabled through innovative product development and practical engineering.
The technology of the 910 series:
Chuck
HSK chucks are available for the smaller sizes.
Larger sizes are optionally equipped with HSK chucks on request. The larger versions are equipped with short taper according to DIN 55027. Manual tool clamping and releasing.
The spindle is equipped with an integral rotary encoder.
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 14.5–120 kW are available. A frequency converter is used to operate the spindle up to its maximum speed. The system is controlled by an integral rotary encoder.
