3.0 Troubleshooting by Symptom
Electrical and Mechanical maintenance should only be carried out by
trained and experienced machine tool engineers who fully understand the
hazards of working with machine tools.
Use this section to begin the process of resolving a service problem. Each problem type is
described in a few words and then more fully described in an explanatory paragraph.
Following this is a chart that directs in the most logical steps.
3.1 Problems Relating to Machining Results
3.1.1 Poor Finish
Poor finish can be caused by a number of variables including: speeds, feeds,
tooling, machine setup and chatter.
Do the following Service Codes:
 Code 33 Software Identification. This is needed if you call Customer Service
 Code 12 Feed Forward Constant
 Code 127 Measures backlash in the system (not used on Dual Feedback
systems)
 Code 128 Enter backlash compensation
Possible Cause
Check This
Inadequate or no Lubrication to
Ballscrews and Way surfaces
Make sure all the Way surfaces are getting proper
lubrication. If not, check to make sure that the lube pump
is functioning properly. Also check for any pinched or
blocked oil lines.
X & Z-axis Drive Trains are loose
Check Repeatability using the Repeatability and Positional
Accuracy procedure. Step by step, carefully inspect the
Drive Train for any looseness. It may be necessary to
disassemble and then reassemble the Drive Train. See
Mechanical Drive Train (X, Z) Section 4.2.
Way surfaces are pocked, scarred, or
excessively worn
Visually check the condition of all the Way surfaces. For
machines that may have excessively worn Way surfaces
you may need to adjust the Gibs in this area. This will
affect performance when using the machine outside of
this area. Check lubrication to affected areas.
Machine set-up problem
Machine’s feet are not equally supporting weight. See
Leveling , Section 2.9.
Tooling problem
Improper tooling, Work piece not properly supported
speeds too fast, Feeds too slow.
See Machine Tool & Setup, Section 4.1.
X gib too tight or loose
See Gib Adjustment , Section 5.2.1.
Loose bearing problem
Looseness in the spindle bearings. Adjust spindle preload.
Ball screw misalignment,
See Mechanical Drive Train (X,Z), Section 4.2. See Spindle
Bearing Preload , Section 5.1.16.
