Spindle bearing GMN high precision ball bearings GMN hybrid ball bearings Use of the highest quality components is the basis for the outstanding performance and long service life exhibited by GMN products. Almost all spindles are equipped with GMN high precision ball bearings. These ensure reliable operation, smooth running and long service life. Hybrid ball bearings are characterized by a combination of materials; bearing steel (inner and outer rings) and ceramic (balls). The material-based characteristics of ceramic balls (in comparison to bearings with steel balls) offer clear performance...

Permanent grease lubrication with air purge Oil-air lubrication Motor and bearing cooling Coolant temperature GMN grease-lubricated spindle bearings ensure reliable, maintenance free operation over the bearing's entire service lifetime. Oil-air lubrication provides a specific supply of lubricant to the spindle bearing and is particularly well suited for very high speeds. GMN high-speed spindles are equipped with an effective liquid cooling system. The spindle's maximum output performance is reached within a specified coolant temperature range of 20 °C to 25 °C. The high-performance greases selected...

These diverse requirements can be substantially covered by a single spindle model with GMN high-speed spindles. They provide – depending on model size – high torque and thus make it possible to achieve high processing performance even in the low speed range. Power and torque characteristics In this catalog, GMN offers high speed spindles in a broad spectrum of model sizes and power ratings. Various motor performance characteristics are available to meet your requirements. Models with a large weak-field area are an economical solution when the power demand in the upper speed range is not very...

Maximum speeds GMN high-speed spindles are designed for processing procedures carried out at extremely high cutting speeds. Their performance profiles indicate the maximum speed values that can be achieved with consideration for the greatest possible running smoothness. Imbalance spindle vibrations Spindle resonance vibrations Vibration calculation Imbalanced mass distribution of rotating parts (spindle shaft, tool) with increasing speed induces sinusoidal imbalance vibrations which may be detrimental to machine operation and the quality of desired processing results. The resonance of rotating...

Tool interfaces GMN standard: Internal taper with flat contact face Because of the very high maximum speed ratings for type UHS, a GMN standard with internal taper/flat contact face and internal threads has been selected. This ensures a secure connection between shaft and tool over the entire speed range for the given spindle. Series UHS (pages 24–25) Internal taper with flat contact face SW ØW Fitting bore with flat contact face Taper hollow shaft with flat contact face: HSK-C Taper hollow shafts (HSK) with flat contact faces are standardized per DIN 69893. The various shapes differ with respect...
