Machine tool spindles are precision components that require the highest level of care and handling. When performing maintenance or sending a spindle in for service, follow these essential safety tips to protect your investment.
When moving spindles with a motor drive package, do not lift the spindle assembly using the motor frame eyebolt only. Make sure the strap placement provides a balanced and stable load.
Take care to protect your spindles even when not in use. It is possible to damage a spindle by improper storage. Store the spindle where there is no risk of collision or excessive vibration. Vibration can cause severe bearing damage when the spindle is not rotating. Use internal and external lubrication to protect against corrosion. Storage areas should be clean and dry, with a stable temperature of 65 to 120 degrees F (18 to 49 degrees C) and at a non-condensing humidity level. This will help prevent contamination from entering the spindle assembly.
We recommend using a log to keep records of the maintenance of the spindle assembly. Rotate spindles by hand several revolutions each month. For a more detailed look at spindle storage, see our article entitled Proper Spindle Storage Preserves Your Investment on the Setco website resources page.
Only operate the spindle assembly at speeds above its nameplate rating. If overspeeding occurs, the spindle may fail due to excessive heat. Do not operate the spindle assembly at rates lower than its nameplate rating. If under-speeding occurs, the spindle may perform poorly. If you ever need assistance with a spindle of any make or model, you can contact the SETCO service team for help.
