4 TIPS TO REDUCE SPINDLE DOWNTIME

Discover the different preventive maintenance procedures to perform to reduce spindle downtime.

The spindle is a robust technology that has the capacity to machine a wide variety of parts from several types of materials such as wood, metal, granite and plastic. It can operate over a very long period, sometimes up to a full day. However, the spindle is one of the components of the CNC machine tool which undergoes the greatest level of wear and which can lead to the complete shutdown of the machine. This causes a significant loss of profits, a reduction in production time and then an increase in costs linked to equipment maintenance.

For these different reasons, the spindle must be subject to a regular maintenance plan. What procedures should be included in the maintenance plan? Here is a list of the main ones.

  • Check the retention force: The retention force is what holds the tool holder in place in the spindle cone. A low level of retention force results in damage to the tool holder and spindle cone. Also, this constraint can significantly reduce the quality of machining. Therefore, it is important to check the retention force of the spindle cone once every 6 months using a retention force gauge.

  • Maintain spindle lubrication level: Lubrication plays a crucial role in spindle longevity and performance. Some spindles are lubricated with grease while others with oil. The latter require that their oil level is always kept above the minimum limit so that there is no contamination. So, it is essential to follow the program and the frequency established by the manufacturer.

  • Monitor the spindle vibration level: The spindle vibration level should never be high. In fact, a high level of vibration causes degradation of certain parts. This problem considerably reduces the quality and efficiency of machining.

  • Inspect the cooling unit: The cooling unit eliminates the heat generated on the different components of the spindle. Without the cooling unit functioning properly, an increase in temperature would then be observed. This would reduce the performance and longevity of the spindle. Therefore, the cooling unit should be checked periodically.

  • By performing daily maintenance on your spindle, you will be able to prevent possible technical problems. You will minimize production downtime, avoid declining profits and will not be forced to continually pay expensive sums to recondition your spindle.
