How Can I Maintain My Machinery’s Spindles?

Maintain Spindles

There are many causes of spindle bearing failure. You can’t always prevent them—things happen, parts wear out and mistakes are made. However, there are specific steps you can take to maintain your machinery’s spindles that will reduce the likelihood of these failures.

Vibration analysis of spindles is one of these steps. How is this accomplished? Use the following tips for this analysis to keep your spindles in top shape.

What is vibration analysis of spindles?

Vibration analysis of spindles involves the use of high-frequency techniques to measure the overall vibration of the spindle and diagnose any bearing damage.

What are the benefits of vibration analysis of spindles?

This analysis can provide early detection of bearing problems such as looseness or imbalance. These issues can be identified before they become major problems or the spindle fails entirely. This prevents increased downtime and reduces the risk of injuries.

How should I collect vibration data?

For best results when collecting vibration data, always measure at the same load and the same speed. Collect data at the same time each month to detect trends. Use one measurement point per spindle. Consider permanently mounting vibration sensors so you don’t have to shut down the machine to collect data. You may also want to include temperature data collection. Increases in temperature often indicate greater friction which indicates lubrication issues.

Who should collect vibration data?

A spindle repair specialist can provide a vibration certification report after a spindle repair is made. Consult with your local spindle experts if you get any vibration readings that differ from the report.

What tools are available to assist with vibration analysis of spindles?

Alarms are available to track vibration issues. When an alarm sounds, this indicates further investigation is needed to determine the cause of the alarm.

What happens if the velocity is too high?

Running a spindle above recommended velocity can cause extensive damage. You may have to install new bearings or regrind shaft bearing journals or housing bores.

What are some other causes of spindle bearing failure?

Vibrations are not the only cause of spindle bearing failure. Other common causes for failure include:

  • Improper storage and handling
  • Incorrect preload
  • Imbalance
  • Contamination
  • Drawbar mechanism failure
  • General wear and tear
  • Age

Who should I contact for maintenance assistance?

Since the causes of spindle bearing failure often relate to poor maintenance, it is important to choose a maintenance provider carefully. Look for specialists who offer expertise in a full range of spindles and related components. Choose a company with a track record of success, with many years of experience in the industry. Read reviews and ask for references, so you can discover the quality of service the company provides.
