The advantages of ATC(automatic tool changer) spindle motor of engraving machine are high speed and good precision. Therefore, we should pay attention to some details in use to avoid damage.

There are several details as following:

  1. Engraving ATC spindle and frequency inverter should be used together. The specifications and parameters of the inverter should match the rated parameters of the spindle. If not set correctly, the engraving motorized spindle will be burned.
  2. Air-cooled ATC spindle：we should check it first when using it. If there is any blockage in the air duct, it should be blown through with compressed air in case of emergency.
  3. Water-cooled ATC spindle: before use, it is necessary to ensure the normal operation of the cooling circulation system. It is strictly prohibited to use it without cooling conditions. The cooling water quantity is calculated according to 1 liter/kilowatt minute. The minimum flow rate of cooling water is not less than 5 liters/minute. The connection between cooling water pipe and nozzle must be reliable and non-leakage.
  4. The coolant must be clean and the temperature should be controlled at 5-30 C. Cooling medium must be forced refrigeration.
  5. It should start at lowest speed before using the ATC spindle. After 30 minutes, the differential progression of the motorized spindle should be 3000. If starting the ATC spindle directly at high speed, abnormal noise, heating and other phenomena will occur, which will affect the service life of the main bearing. It’s necessary to power on the ATC spindle (at low speed) for at least 15-30 minutes in a week during long-term preservation.
  6. When fixing cutters on carving motorized spindle, it is necessary to clean the conical holes in the cylinder clamp and nut so as to avoid affecting the accuracy.
  7. Check the rotation direction of the engraving ATC spindle which should be the same as that of the milling cutter. If it does not conform to the three power lines, we should change two arbitrarily to make it consistent with the direction of the milling cutter.
