What to do if the headstock moves on my Powermatic 3520B Lathe when using the tailstock?
If the headstock of your Powermatic Lathe moves when applying pressure with the tailstock, it's likely that you're applying excessive pressure (more than 500 lbs of force). To resolve this, slide the headstock to the left end and then apply only sufficient force with the tailstock to hold the workpiece securely in place.
Why does the tailstock move when applying pressure on my Powermatic 3520B?
If the tailstock on your Powermatic Lathe moves when applying pressure, the cam lock nut might need adjusting; tighten it. Another possible cause is greasy or oily surfaces on the lathe bed and tailstock mating surfaces. Remove the tailstock and clean these surfaces with a cleaner/degreaser, then re-apply a light coat of oil to the lathe bed surface.
Why does my Powermatic 3520B Lathe motor fail to develop full power?
If your Powermatic Lathe motor isn't reaching its full power, there might be a few reasons. First, check if the power line is overloaded and correct it. Another cause might be undersized wires in the power supply system, in which case you should increase the supply wire size. If those aren't the problem, the inverter might be faulty, or the motor could be worn and needs replacing. For a faulty inverter, it is recommended to contact WMH Technical Service; for a worn motor, replacement is the solution.
Why is my Powermatic 3520B vibrating excessively?
If your Powermatic Lathe experiences excessive vibration, it could stem from several issues. Begin by inspecting the workpiece for warping, out-of-roundness, major flaws, or improper preparation. Correct any issues by planing or sawing the workpiece, or replace it with a new one. Also check for worn spindle bearings, which would require replacement. Other potential causes include a worn drive belt (replace it), a loose motor mount lock handle (tighten it), or the lathe being on an uneven surface (adjust the levelers).
What to do if my Powermatic 3520B motor or spindle stalls?
If your motor or spindle stalls or won't start on your Powermatic Lathe, here's what to check: First, see if you're taking too deep of a cut and reduce the depth of cut. Also, verify the belt adjustment and condition. If it is improperly adjusted, worn, or broken, adjust or replace the belt as needed. Ensure the motor is properly cooled by blowing out any sawdust from the motor housing fan. Lastly, inspect the spindle bearings and motor for wear; replace them if necessary.
Why does my Powermatic Lathe run at one speed only?
If your Powermatic Lathe only runs at one speed, the potentiometer might be faulty, requiring a replacement. It is also possible that the electronic AC inverter is not programmed properly, is defective, or has loose wiring. For these inverter-related issues, it is recommended to contact WMH Technical Service for assistance.
How to stop tools from grabbing on my Powermatic Lathe?
If your tools tend to grab or dig in while using the Powermatic Lathe, ensure your tools are sharp. Dull tools are often the culprit, so keep them sharpened. Also, check the tool support height; if it's set too low, reposition it. Similarly, if the tool support is too far from the workpiece, move it closer. Lastly, make sure you're using the correct tool for the specific operation.
