Jäger SP33-M260.01 S26 Manual

Technical descriptionItem no. 13502000, Revision 04 11 ( 36 )5.2 Electrical connectionThe HF spindle may only be operated with a frequency converter (FC).Ü Check whether the current, voltage, and frequency data of the HF spindlematch the raw data for the frequency converter.Ü Use a motor supply line that is as short as possible.Ü Adjust the speed of the HF spindle using the FC.Ü Refer to the frequency converter manual for further information.The FC detects the following operating states of the HF spindle, depending onthe version:q HF spindle rotating.q HF spindle too hot.q HF spindle at a standstill, etc.The FC forwards the operating states of the HF spindle to the machine con-troller.Note: Protection by means of interrupting the electrical connection.The HF spindle connection is equipped with a safety function.If the machine's main spindle rotates in an uncontrolled manner:q The safety function interrupts the electrical connection of the HF spindle.Damage to the HF spindle, machine, and controller is minimized.5.3 CoolingThe HF spindle does not feature built-in cooling. However, this means that ithas a lower power than an HF spindle with cooling.Note: Extension of the service life through heat dissipation.Heat is produced during operation of the HF spindle. The temperature of theHF spindle should not exceed + 45° C as this shortens the service life of thebearing.u Check the temperature of the HF spindle on the housing.u Dissipate the heat using the spindle holder.5.4 Sealing airFor guidelines on air quality,see "Air purity classes (ISO8573-1) [} 24]" section.The sealing air prevents foreign bodies such as chips and liquids (e.g. emul-sions) from entering the HF spindle.Ü Check that air escapes at the front between the housing and the rotatingparts of the HF spindle.
