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...

Requirements Motor spindles with improved performance, rigidity and reliability are the essential prerequisites for economical milling production in many fields of application. Depending on the processing task, it is important that a broad spectrum of different tools can be employed to the full extent of their performance capabilities: Large tools demand high power at relatively low speeds, whereas a relatively low power demand is often sufficient for small tools. These diverse requirements can be substantially covered by a single spindle model with GMN high-speed spindles. They provide - depending...

This feature provides a substantial improvement...

Maximum speeds Imbalance spindle vibrations 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. 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...

GMN standard: Internal taper with flat contact face Series UHS (pages 24-25) 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. Internal taper with flat contact face Interface GMN standard: Fitting bores with flat contact face Series HS, HV-X, HSX (pages 26-41) High-speed spindles in type series HS, HV-X and HSX are equipped with the GMN standard - fitting bore/flat contact face and internal...
