5 Diagnostics
This section explains the diagnostic procedures used to isolate service problems.
5.1 The Machine Tool & Set-Up
5.1.1 The Milling Machine Checklist
The following is a quick reference for the types of problems that may arise if problems are noticed in these
areas.
Problems With: Can Contribute To: Most Likely When (and why):
Spindle bearings
See Spindle cartridge
replacement
Noisy head
Parts incorrect
Circles out of round Older machines, machines that
are pushed hard, spindle run at
high RPM’s for long periods of
time.
Lubrication system
Premature wear of ball screws
and linear guides
Poor part finish
New installations (may not be
hooked up or line sheared)
Linear guides worn Poor finish
Out of round circles
Faulting Inadequate lubrication
It should take many years for
this to become a problem.
Machine not level
Weight not distributed evenly on
all 4 feet
See Leveling procedures
Parts incorrect
Machine geometry off, i.e. tram. New installation, after moving
machine or heavy crash.
Head out of tram Leaves uneven surfaces on
bottom of pockets. Circles are
not round when circularity is
checked.
Machine not level or after a
heavy crash.
Water in air lines Faulty solenoid valves
Rust
Problems with the pneumatics on
the tool carrier and tool change
air cylinder
User does not drain air
regular/water separator on a
regular basis
Users shop has a poorly designed
air system with no air dryers to
prevent water from entering lines
Ignoring periodic maintenance
such as checking oil cup on tool
unclamp cylinder and greasing
fittings on ATC
Lack of lubrication to cylinder
and premature failure
Wear of sliding surfaces on ATC
and premature failure
User does not perform
recommended periodic
maintenance on machine tool.
5.1.2 A Special Word About Linear Guides
The linear guides on your 2 OP are vital to the performance of the machine.
They should require very little maintenance over the life of the guides. It is recommended that these
guides be inspected for any signs of excessive wear. Lubrication is the key to the longevity of the guides so
it is important to verify oil is reaching the guides. It is also a good idea to make sure no cutting fluids or
chips are reaching the guide surfaces. Periodic cleaning or inspection of the guides is recommended.
It is good machining practice to avoid the use of compressed air to clean swarf off a machine. This risks
blowing swarf into the linear way surfaces and compromising the performance of the machine.
