4.0 Diagnostics
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.
This section explains the diagnostic procedures used to isolate service problems.
4.1 The Machine Tool & Set-Up
4.1.1
Leveling
Leveling is one of the most important aspects of setting up the machine properly.
Improper leveling can lead to a variety of machining problems.
The machine should be level to within .02 mm longitudinally and .01 mm
transversely. See Leveling Procedures, Section 2.9.
4.1.2
A Special Word About The X Gib
The X gib is vital to the performance of your lathe.
Gibs should be:
flat
free of twist
free of burrs
free of blockages in the oil passages and channels
Defective or scarred gibs must be replaced. Shimming of gibs will not yield
acceptable results.
It is good machining practice to avoid the use of shop air to clean the chips off a
machine. This risks blowing chips into the sliding way surfaces and compromising
the performance of the machine.
See Gib Adjustments, Section 5.2.1.
4.1.3 Lubrication
Lubrication is one of the single, most important maintenance issues and plays a key
role in assuring the performance and durability of the lathe. At the beginning of each
day manually supply oil to the way surfaces by doing service code 300.
Lack of lubrication can lead to a variety of problems with your machine motion due to
increased friction in the sliding ways. This increased friction may lead to part
inaccuracies and decreased life expectancies of your ballscrews and way surfaces.
Lack of lubrication in the headstock can lead to increased wear of the gear train as
well as premature wearing or failure of the spindle bearings. For the 1630, oil will be
flowing only when the spindle is on.
4.1.4 Machining Set-Up
The machining set-up itself is always something that can greatly influence the
performance of the lathe. The following are some things to keep in mind.
