In modern industrial production, precision electric spindles currently used in the market often encounter various situations. Now, let's provide a detailed introduction to precisionHigh speed electric spindleProblem prone to malfunction:

1、 Excessive working noise of precision high-speed electric spindle

1. Poor dynamic balance of the spindle components leads to excessive vibration during spindle rotation, resulting in working noise. This situation requires professional personnel from the machine tool manufacturer to recheck and debug all spindle components for dynamic balancing.

2. The wear of the main shaft transmission gear causes excessive clearance between the gears, resulting in excessive impact vibration during the rotation of the main shaft and generating working noise. Professional personnel from machine tool manufacturers need to inspect, repair, or replace spindle drive gears.

3. The main shaft support bearing may become rough or damaged, causing excessive clearance between the main shaft rotation, resulting in excessive impact and vibration during rotation, and generating working noise. Professional personnel from machine tool manufacturers need to inspect, repair, or replace bearings.

4. Loose or worn spindle drive belts can cause excessive friction during spindle rotation, resulting in operational noise. This situation can be eliminated by adjusting or replacing the transmission belt.

2、 Precision high-speed electric spindle generates heat

1. The excessive pre tightening force of the spindle bearing leads to excessive friction during spindle rotation, resulting in a sharp increase in spindle temperature. This situation can be eliminated by readjusting the preload of the spindle bearings.

2. Grinding or damage to the spindle bearings can also cause excessive friction during spindle rotation, leading to a sharp increase in spindle temperature. This situation can be eliminated by replacing the bearings with new ones.

3. Dirt or impurities in the spindle lubricating oil can also cause excessive resistance during spindle rotation, leading to an increase in spindle temperature. It can be eliminated by cleaning the spindle box and changing the oil again.

4. The use of lubricating grease or excessive lubricating grease in the spindle bearings can also cause excessive resistance and friction during spindle rotation, leading to an increase in spindle temperature. This situation can be eliminated by reapplying lubricating grease.

3、 Precision high-speed electric spindle stops rotating during strong cutting

1. The transmission belt between the spindle motor and the spindle is too loose, resulting in insufficient torque transmission from the spindle. During strong cutting, insufficient spindle torque leads to an alarm and automatic shutdown of the CNC machine tool. The handling method for this situation can be eliminated by readjusting the tension of the spindle drive belt.

2. The surface of the transmission belt connecting the spindle motor and the spindle has oil, which causes the transmission belt to slip when driving the spindle. When the spindle torque is insufficient during strong cutting, an alarm will be generated, and the CNC machine will automatically stop. Clean with gasoline or alcohol and then wipe clean to eliminate it.

3. The transmission belt connecting the spindle motor and the spindle has been in use for too long and has failed, resulting in the inability of the spindle motor to transmit torque. During strong cutting, the spindle torque is insufficient, causing the CNC machine tool to alarm and automatically shut down. It can be eliminated by replacing the spindle drive belt with a new one.

4. The clutch and coupling connections in the spindle transmission mechanism are too loose or worn, resulting in excessive torque transmission errors in the spindle motor and strong spindle vibration during strong cutting. Generate an alarm, and the CNC machine will automatically shut down. This situation can be eliminated by adjusting or replacing the clutch or coupling.

4、 Precision high-speed electric spindle cutting tools cannot be clamped

1. The displacement of the disc spring is too small, causing the spindle clamp and clamping device to fail to reach the correct position, and the tool cannot be clamped. This situation can be eliminated by adjusting the stroke length of the disc spring.

2. The spring clamp is damaged, causing the spindle clamping device to be unable to clamp the tool. It can be eliminated by replacing the spring clamp with a new one.

3. The failure of the disc spring resulted in the spindle tool holder and clamping device being unable to move to the correct position, causing the tool to be unable to clamp. It can be eliminated by replacing the disc spring with a new one.

4. The pull pin on the handle is too long and collides with the spindle claw and clamping device, making it unable to move to the correct position, and the tool cannot be clamped. It can be eliminated by adjusting or replacing the rivets and installing them correctly.

5、 The tool clamping of high-speed electric spindle cannot be loosened

1. The pressure and stroke of the loosening knife hydraulic cylinder are insufficient. This situation can be eliminated by adjusting the position of the hydraulic pressure and travel switch.

2. The compression of the disc spring is too tight, causing the spindle clamping device to not move completely to the correct position and the tool to not be released. It can be eliminated by adjusting the nut on the disc spring to reduce the compression of the spring.
