What makes the spindle motor broken?

We all know that the internal structure of the engraving machine spindle is core and coil,
long working hours makes it continuous heating.

There are two ways of cooling system for CNC router. One is cooling water circulating
motor, and the other is air-cooled motor. Generally, the water cycle motor produces
lower noise than the air-cooled motor. While the air-cooled motor has no trouble replacing
the circulating pure water.

The air-cooled motor is more suitable for the user who lived in the cold north, where the
water is easy to icing.

Water circulation cooling of motor must be purified water. It is for preventing clogging of
the spindle motor. The spindle motor continues to heat up, carving precision will be
reduced, or even lost step dislocation. To promptly resolve the gridlock by blow out with
air pump blockage or by a high-pressure water jets after softening blockages with acid.

In summer, the CNC Router operators need to frequently check the water temperature of
the circulating water, and he must insure the timely replacement of the cooling water. In the
cold winter, it can prevent the water from freezing by pour in antifreeze.

After prolonged high-intensity work, the spindle motor of tombstone engraving
machine is in high temperature. The user need to stop the machine and rest for some
time, and then continue to work. COMEID marble tombstone engraving machine installed
water spray cooling next to the spindle motor which helps the spindle motor and the tool
knife cooling, thus it extending the service life of the spindle motor and the tools.
