The reason for abnormal noise on the spindle belt of a horizontal machining center refers to a machining center set parallel to the spindle axis and workbench, mainly suitable for processing box type parts. Its working principle is that after the workpiece is clamped once on the machining center, the computer can automatically select different cutting tools, automatically change the spindle speed of the machine tool, and sequentially complete the processing of multiple processes on multiple surfaces of the workpiece.

Sometimes when we use it, the spindle belt may make abnormal noises. What is the reason for this? Let's take a look together!

1. The belt connecting the spindle to the servo motor is damaged

The spindle belt of a machining center that has been used for a long time may be worn to some extent and may cause abnormal noise. Generally, we require the spindle manufacturer to choose a high-quality spindle belt of a matching brand.

2. Abnormal noise caused by mismatch between the tooth shape of the transmission belt and the tooth shape of the servo motor and spindle

This problem does not occur during the initial assembly of the machining center manufacturer. In many cases, the customer matches a belt with teeth that do not match the teeth of the servo motor and spindle during replacement, which can cause abnormal noise during use. We generally recommend that when there is abnormal noise on the spindle belt of the machining center, users can promptly contact our after-sales technical team to choose a suitable belt to avoid the abnormal noise caused in this situation.

3. Abnormal noise caused by excessive tension of the spindle belt

During the initial assembly, the tension between the spindle and the servo motor belt should not be too tight, as it can accelerate belt wear and may cause abnormal noises.

4. Low tension of the spindle belt can also cause abnormal noises

The tension of the belt connecting the spindle to the servo motor should not be too low. If the tension is too low, the belt connection is too loose. In this case, heavy cutting processing can easily cause the belt to slip and also make abnormal noises.
