It is normal for the spindle of the engraving machine to heat up during operation. If the heat is too high, it will affect the performance and life of the spindle. Let’s explore the reasons for the heating of the cnc router machine woodworkingspindle:

The bearing of the electric spindle will generate a lot of heat when it rotates at high speed, which will cause the temperature of the spindle to rise, and the cutting tool installed at the end of the electric spindle will also generate a lot of heat during high-speed cutting.

During the high-speed operation of the electric spindle motor, power loss (including mechanical loss, electrical loss, etc.) is generated internally, thereby causing the motor to heat up. Since the electric spindle motor is installed in the spindle unit casing, the spindle motor cannot be directly dissipated by a fan, and the natural heat dissipation conditions are also relatively poor. The survey results show that when the motor rotates at high speed, the working temperature of the motor rotor reaches 140-160℃, and the temperature of the stator is also 45-85℃. The heat generated by the motor will be directly transferred to the spindle, causing thermal deformation of the spindle and resulting in machining errors.

It should be reminded here that when purchasing, pay attention to what kind of heat dissipation method is used, and whether the spindle motor adopts high-precision bearings. service life. Each product is not a fixed configuration. The standard configuration of the spindle of the engraving equipment has different configurations according to the specifications of the equipment.

The above is the reason for the heating of the CX-1325 advertising cnc router spindle. In the next issue, we will talk about the ways of dissipating the heat of the engraving machine spindle. If you have any questions, please consult the official website of IGOLDEN CNC.
