No or low air pressure Air supply to the machine.
Is the pressure regulator set at 90psi?
Is there a leak in the pneumatic system?
Are the tool holders or the spindle
taper bore dirty?
Examine the spindle taper bore and the tool holder for embedded
chips and “tackiness” from excessive coolant residue. Sometimes
holders that are worn or have defects on the taper will stick in the
spindle.
The pull stud you are using is not
correct for this machine
See section 2 for an illustration of the correct pull stud.
Loose tool holder pull stud Check that the pull stud is tightened to between 70 and 85 ftlbs
Belleville washers are damaged,
worn or fatigued.
With a BT30 tension gauge, check the pull strength of the draw bar,
it should be approximately 500kgs.
The pull fingers inside the spindle
have become loose
Check the fingers are tightened to 20 ftlbs.
The pull fingers inside the spindle
have been damaged
Remove the pull fingers and visually inspect for damage and replace
as necessary
4.4.4 Air is not blowing through the spindle during a tool change
Air should blow through the spindle when a tool holder is being removed, whether automatically or
manually. The amount of air that flows down the spindle is controlled by a flow control valve at the rear of
the machine. See drawing 27563-2. Press the green button on the head when the door is open to check
this.
Possible Cause Check This
No or low air pressure Air supply to the machine.
Is the pressure regulator set at 90psi?
Is there a leak in the pneumatic system?
The flow control valve is not
adjusted properly
Check that the flow control valve is adjusted outward from the
closed position.
There is a blockage Check that there are no kinked lines.
The solenoid labeled 1 on drawing
27563-2 has failed or is not
receiving an electrical signal.
If the solenoid is receiving a signal from the computer module, then
press the red button to fire the solenoid to see if it works when
commanded manually.
4.5 Control Input or Output Problems
4.5.1 Control reports low air pressure
The Control has the ability to display a number of different messages depending on the status of the
machine. A low air message would be displayed as ‘AIR PRESSURE LOW’. The following chart describes
possible causes to this condition.
Possible Cause Check This
Air line pinched Check that air hose is not pinched or bent.
