symptom possible Cause possible solution
tool slips in collet. 1. Collet is not fully drawn up into
spindle taper.
2. Wrong size collet.
3. debris on collet or in spindle taper.
4. taking too big of a cut.
5. Making a climb cut.
1. tighten drawbar.
2. Measure tool shank diameter and match with
appropriate diameter collet.
3. Clean collet and spindle taper.
4. lessen depth of cut and allow chips to clear.
5. reverse feed direction to avoid climb cuts.
Breaking tools or cutters. 1. spindle speed is too slow/feed rate
is too fast.
2. Cutting tool getting too hot.
3. taking too big of a cut.
4. spindle extended too far down.
1. set spindle speed correctly ( page 29) or use a
slower feed rate.
2. use coolant fluid or oil for appropriate application.
3. decrease depth of cut.
4. Fully retract spindle and lower headstock. this
increases rigidity.
Workpiece vibrates or
chatters during operation. 1. table locks not tight.
2. Quill lock lever not tight.
3. Workpiece not securely clamped to
table or into mill vice.
4. spindle speed is too slow/feed rate
is too fast.
5. spindle extended too far down.
1. tighten down table locks ( page 35).
2. tighten quill lock lever ( page 31).
3. Check that clamping is tight and sufficient for the
job. Make sure mill vice is tight to the table.
4. set spindle speed correctly ( page 29) or use a
slower feed rate.
5. Fully retract spindle and lower headstock. this
increases rigidity.
table is hard to move. 1. table locks are tightened down.
2. Chips have loaded up on ways.
3. Ways are dry and need lubrication.
4. table limit stops are interfering.
5. gibs are too tight.

3. lubricate ways and handles ( page 39).
4. Check to make sure that all table limit stops are not
in the way.
5. adjust gibs (see page 43).
Bad surface finish. 1. spindle speed is too slow/feed rate
is too fast.
2. using a dull or incorrect cutting tool.
3. Wrong direction of rotation of cutting
tool.
4. Workpiece not securely clamped.
5. spindle extended too far down.
1. set spindle speed correctly ( page 29) or use a
slower feed rate.
2. sharpen cutting tool or select one that better suits
the operation.
3. Check for proper direction of cutting rotation for
cutting tool.
4. secure properly to the table.
5. Fully retract spindle and lower headstock. this
increases rigidity.
