CommissioningItem no. 10302178, Revision 0226 ( 40 )9 CommissioningDANGER: Due to flying parts.If the speed is selected incorrectly, the HF spindle or the tool may be de-stroyed and their fragments may be flung out.u Note the maximum speed for the selected tool.u Note the maximum speed for the HF spindle.u The maximum permissible speed of the HF spindle for commissioning /processing is always the lowest specified speed.Example of design: Inserting theshankNote: Ensure functionality.u Never operate the HF spindle without a clamped tool shank.If no tool shank is clamped:q The clamping system is damaged by the centrifugal forces.q The clamping system is shifted.q The balance of the HF spindle is affected.q The bearing is damaged.Example of design: ClockwiseÜ Turn the shaft of the spindle at least ten times by hand.9.1 Daily start-upProceed as follows to preheat the grease lubrication of the bearing and toprotect it:Ü Operate the HF spindle with a clamped tool (without machining).Ä Approx. 2 minutes.Ä At maximum 50 % of the maximum permissible speed.(See Commissioning [} 26] section)This brings the HF spindle to its operating temperature.9.2 Shutdown signalUse the option on the frequency converter of detecting the shutdown signalfrom the shaft and forwarding this to the machine controller for evaluation.9.3 Commissioning after storageÜ Do not put the HF spindle into operation until its temperature has adjustedfrom the temperature of the storage location to the temperature of the us-age location.Ä The temperature difference between the HF spindle and the usage lo-cation should not exceed 10°C.Ü Carry out all steps in the "Maintenance [} 32]" section.
