Symptom
Tool slips in spindle.
Breaking tools or cutters.
Workpiece vibrates or
chatters during operation.
Table is hard to move.
Bad surface finish.
Model G0762 (Mfd. Since 5/14)
Possible Cause
1. Tool not fully drawn up into spindle
taper.
2. Debris on tool or in spindle taper.
3. Taking too big of a cut.
1. Spindle speed/feed rate too fast.
2. Tooling too small.
3. Tooling getting too hot.
4. Taking too big of a cut.
5. Spindle extended too far down.
1. Table locks not tight.
2. Workpiece not secure.
3. Spindle speed/feed rate too fast.
4. Spindle extended too far down.
1. Table locks tightened down.
2. Chips loaded up on ways.
3. Ways dry and need lubrication.
4. Table limit stops are interfering.
5. Gibs too tight.
1. Spindle speed/feed rate too fast.
2. Using dull or incorrect tooling.
3. Wrong spindle rotation of tooling.
4. Workpiece not secure.
5. Spindle extended too far down.
Possible Solution
1. Tighten drawbar.
2. Clean collet and spindle taper.
3. Lessen depth of cut and allow chips to clear.
1. Set spindle speed correctly (Page 29) or use slower
feed rate.
2. Use larger tooling and slower feed rate.
3. Use coolant or oil for appropriate application.
4. Decrease depth of cut.
5. Fully retract spindle and lower headstock. This
increases rigidity.
1. Tighten table locks.
2. Properly clamp workpiece on table or in vise.
3. Set spindle speed correctly (Page 29) or use a
slower feed rate.
4. Fully retract spindle and lower headstock. This
increases rigidity.
1. Make sure table locks are fully released.
2. Frequently clean away chips that load up during
operations.
3. Lubricate ways (Page 33).
4. Check to make sure that all table limit stops are not
in the way.
5. Adjust gibs (see Page 38).
1. Set spindle speed correctly (Page 29) or use a
slower feed rate.
2. Sharpen tooling or select one that better suits the
operation.
3. Check for proper cutting rotation for tooling.
4. Properly clamp workpiece on table or in vise.
5. Fully retract spindle and lower headstock. This
increases rigidity.
