Spindle Maintenance

Increased vibration typically points to worn spindle bearings, so be sure to replace them when necessary. 4. Maintain spindle-bearing lubriion. Although closed-unit spindles typically are factory lubried for life, large spindle headstocks – such as those on big turning machines – need oil baths to lubrie their bearings.

An Overview of Bearing Vibration Analysis

result bearing manufacturers have developed vibration tests as an effective method for measuring quality. A common approach is to mount the bearing on a quiet running spindle and measure the radial velocity at a point on the bearing’s outer ring in three frequency bands, 50-300, 300-1800 and 1800-10000Hz. The bearing must meet RMS velocity
