High frequency spindles for manual tool change Increase of power and torque as the tables indicate. In addition, reliability, .The working life of HSX-spindles in comparison to the With the improvements of power, load carrying capacity and stiffness in the HV-X designs the working range of single spindles is extended over the previous models. These enhancements minimize the number of spindles required to cover a large speed range. The special motor design also permits the use of more economically sized frequency converters to match the application requirements. . . The GMN product line...

High frequency spindles for manual tool change Advantages Of Hybrid Ceramic Bearings GMN high frequency spindles utilize hybrid ceramic ball bearings. These bearings have standard steel bearing races and are matched with silicon nitride balls. Advantages of hybrid bearings compared with normal spindle bearings are: Axial shaft movement As a result of the lightweight ceramic balls, centrifugal forces are reduced with a corresponding reduction in dynamic movement of bearing races. In addition, movements due to less friction and the lower coefficient of expansion of ceramics are reduced....

High frequency spindles for manual tool change Bearing Systems Spring preloaded single bearings Spring preloaded bearing sets ► Minimal temperature variations due to liquid cooling of the motor and front bearings complement. ► All mounting and critical datums are hardened and ground for longer service life. ► Horizontal spindle mounting. Differing position on request. ► Monitoring of motor temperature via temperature ► Short, rigid construction due to the high-frequency motor being placed between the bearing sets, results in favorable critical speeds, far exceeding the operating speed. ►...

High frequency spindles for manual tool change Lubrication System Oil/air lubrication Lubrication drain Oil pump Oil metering valve Mixing chamber High reliabilty in operation due to separate supply to each bearing group and exact quantity of volume. u Ecological compatibility because of minimum oil consumption and elimination of oil mist. Long life and high load carrying capacity as a result of the use of oils with additives like EP and HT. u Large spectrum of applicable oils. Grease lubrication + Air purge
