Users of CNC engraving machine will inevitably encounter the problem of spindle failure during use. There are many reasons for the damage of the spindle, including the quality of the spindle itself and the conditions of use. The quality of the spindle is the most important factor that directly affects its service life. The work intensity of the spindle is very high. Therefore, when choosing a spindle, choose a good spindle as much as possible within your budget. In a high-intensity work environment, poor quality spindles will inevitably appear.

Different CNC engraving machine are equipped with different spindles. Such as ordinary CNC wood engraving machine and stone engraving machine. The cutting force of stone carving is much greater than that of wood carving, and the power of the main shaft of the stone machine is also more powerful, and a water cooling device needs to be added during the carving process. The spindle requirements of CNC wood engraving machine are not so high. Therefore, knowing the working mode of the spindle and using the spindle correctly for processing is also one of the ways to avoid damage to the spindle.

The spindle cooling system does not work well. The cooling system of the spindle of the engraving machine is mainly divided into air cooling and water cooling. Especially for users who use water cooling, if the water circulation system is not good for a long time, or if the water circulation is often forgotten during work, the spindle speed of the engraving machine can reach 24,000 rpm per minute. Continuous high-intensity working time is too long, and the spindle is not cooled in time, and high heat will be generated after a long time of work. At this time, the pressure of the spindle bearing will increase, and the spindle is easily damaged and scrapped. Therefore, we recommend that the working time of the engraving machine should not exceed 12 hours.

The impact of improper operation, when the CNC engraving machine is working, if the spindle speed does not reach the specified working speed, it is also easy to cause damage to the spindle. Secondly, when engraving materials of different materials, different speeds should be set. When the spindle is subjected to different engraving resistance, if the speed is not adjusted in time, the spindle will be damaged.

Insufficient antifreeze measures in winter. Due to the low temperature in winter, water is easy to freeze. After use, the residual water inside the spindle should be discharged in time. If this problem is not paid attention to in time, the residual water will cause the spindle to freeze. Therefore, in cold areas, we recommend that you add antifreeze to prevent unnecessary damage caused by freezing the spindle in winter.

These are common reasons for spindle damage. If you have any questions about the use, maintenance and repair skills of the spindle, please feel free to contact us. We will have a dedicated after-sales service team and technical team to help you answer.
