Maintenance of Dynamic and Static Pressure Spindles

Time:2024/7/11 11:32:00Seo:http://en.zjsxds.cn/news1028295.html

The maintenance of the dynamic and static pressure spindle is the key to ensuring its long-term stable operation and extending its service life. The following is a detailed explanation of the maintenance of the dynamic and static pressure spindle:


1、 Regular inspections

Bearing wear condition: Regularly check the wear condition of the bearings, including checking the clearance of the bearings, the smoothness of the rolling surface, etc., to ensure the normal operation of the bearings.

Temperature and vibration: Check the temperature and vibration of the spindle to ensure that it is within the normal range. Excessive temperature and abnormal vibration can be precursors to spindle failure.

Electrical connection: Regularly check the stability of electrical connections to ensure that electrical components are not loose or damaged, in order to avoid electrical faults affecting the operation of the spindle.

2、 Cleaning and lubrication

Cleaning: Regularly clean the surface of the spindle and bearings, remove external impurities such as dust and iron filings, and maintain the cleanliness of the spindle. When cleaning, appropriate cleaning agents and tools should be used to avoid damage to the spindle.

Lubrication: Lubrication should be carried out according to the operating instructions of the machine tool to ensure sufficient lubrication of the spindle. The selection of lubricating oil should be determined based on factors such as the material and working conditions of the spindle, and added and replaced according to requirements.

3、 Fuel supply system inspection

Oil supply pressure: Before starting the spindle, check whether the pressure of the oil supply system is normal. If the fuel supply pressure is insufficient, the fuel supply system should be adjusted or repaired in a timely manner.

Oil quality: Regularly check the quality of the oil, including its viscosity, cleanliness, etc. If the oil deteriorates or becomes severely contaminated, it should be replaced with new oil in a timely manner.

4、 Reasonable use and operation

Load control: When using the spindle, its working load should be strictly controlled to avoid overload operation. Overloading operation will accelerate the wear and aging of the spindle, shortening its service life.

Avoid impact: When replacing parts such as the spindle belt and grinding wheel, it should be done with the spindle supplied with oil to avoid pulling the spindle and bearings without oil. At the same time, it is important to avoid any impact or collision with the spindle during operation.

5、 Regular maintenance and upkeep

Replace worn parts: Regularly check the wear of the spindle and replace worn parts in a timely manner, such as bearings, sealing rings, etc.

Adjustment and calibration: Regularly adjust and calibrate the spindle to ensure its accuracy and stability meet the requirements.

6、 Precautions

Strictly prohibit illegal operations: it is strictly prohibited to use spindle oil or spindle oil that does not comply with regulations; It is strictly prohibited to mix water, cutting fluid, grinding fluid and other liquids or impurities into the spindle oil; It is prohibited to start the spindle motor when the oil supply system is not started or the spindle oil supply pressure is lower than the specified value.

Exception handling: If any abnormal conditions such as spindle temperature rise, spindle vibration, and spindle running noise are found during spindle use, the machine should be stopped for inspection and handling in a timely manner.

In summary, the maintenance of the dynamic and static pressure spindle needs to start from multiple aspects, including regular inspection, cleaning and lubrication, oil supply system inspection, reasonable use and operation, regular maintenance and upkeep, and precautions. Only by doing these tasks well can we ensure the long-term stable operation of the dynamic and static pressure spindle and extend its service life.
