Possible Solution
1. Remove and re-install (Page 21).
2. Clean tool and spindle taper, then re-install.
3. Decrease feed pressure and allow chips to clear.
1. Reduce spindle speed; reduce feed rate.
2. Decrease feed pressure and allow chips to clear by
raising but up then moving back down.
3. Use right technique, tool, or machine for job.
4. Use coolant or oil for appropriate application (Page
19); reduce cutting speed (Page 20).
5. Retract spindle and raise table to increase rigidity.
1. Retract spindle and raise table to increase rigidity.
2. Tighten table lock or lock bolt (Page 22).
3. Properly clamp workpiece on table or in vise.
4. Reduce spindle speed (Page 20); reduce feed rate.
1. Disengage table lock (Page 22).
2. Clean away chips/debris. Lubricate column.
1. Allow drill press to cool. Avoid operating at high
speeds for extended time.
1. Replace spring/increase return spring tension
(Page 30).
2. Clean and lubricate spindle/quill rack.
1. Correctly sharpen drill bit.
2. Correctly install tool/bit.
1. Properly clamp workpiece.
2. Use appropriate lubrication for application (Page
19).
3. Remove and re-install (Page 21).
4. Adjust spindle speed (Page 20); feed rate.
1. Properly clamp workpiece on table or in vise;
decrease feed speed.
1. Remove chuck, clean, deburr tapered chuck and
spindle mating surfaces, reassemble.
2. Install tool/bit correctly or replace (Page 21).
3. Replace spindle bearings.
1. Adjust pointer on depth stop stud.
1. Install scrap board between table and workpiece.
