What is the reason for the non rotation of the equipment spindle

The transmission system of the horizontal machining center spindle includes direct connection and synchronous belt transmission. However, in the application process of CNC machining with synchronous belt transmission, the equipment spindle does not rotate. What is the reason for this? Next, let's introduce it to us by the editor Da Bai.

1. Gear transmission problem caused: Check if the synchronous belt transmission of the horizontal machining center spindle is dry and cracked.

2. The three-phase power supply of the spindle is out of phase or in reverse: Check the switch power supply and replace any two power plugs.

3. Line connection error: Carefully refer to the line connection guide to ensure proper connection.

4. There is no corresponding spindle control signal export for the management system: Use a multimeter to measure the output port of the management system signal. If there is no spindle control signal export, the relevant IC electronic devices need to be replaced or sent to the factory for repair.

5. The management system has a clear spindle control signal export, but there is a short circuit or electronic device damage in the power supply distribution line and control signal output line. Use a multimeter to check the power supply circuit between the horizontal machining center management system and the spindle motor. There is no short circuit in the signal control circuit, and there is no short circuit in the signal control circuit. Check if the contact points between the connecting lines are poor, and communicate with AC contactors, Check if the DC relay is damaged, check if the thermal relay is overcurrent, and check if the fuse tube is damaged.
