1.Exceed the limit of hard limit switch
Possible causes:
(1) Triggering of hard limit switch.
(2) Poor contact or breaking of signal line for hard limit switch.
(3) Damage of hard limit switch.
Solution:
(1) Press Limit Release button and operate MPG to make limit piece off limit switch.
(2) Replace signal line or find out the connection point with poor contact.
(3) Replace hard limit switch.

2.Exceed the travel limit of software
Possible causes:
(1) Wrong setting of work piece origin.
(2) Wrong machining program.
(3) Wrong setting of tool length offset or work piece origin in case that Z-axis exceeds travel limit of
software.
Solution:
(1) Check the setting of work piece origin.
(2) Replace machining program.
(3) Check tool length offset.
(4) Check origin offset.

3.Failure of tool loosening for spindle
Possible causes:
(1) Insufficient air pressure and air flow.
(2) Tool shank is rusty or with rust and foreign matter.
(3) Damage or no signal of solenoid valve for tool loosening.
(4) Problem with signal for tool loosening of spindle.
(5) Problem with spindle.
Solution:
(1) Increase air pressure and air flow.
(2) Remove the rust and foreign matter on the tool shank.
(3) Measure the signal line of solenoid valve for tool change or replace the solenoid valve.
(4) Adjust the location of signal for tool loosening of spindle, check whether the I board of system is
damaged, whether poor contact or short circuit exists in the signal line.
(5) Return the spindle to factory for maintenance.

4.Failure of tool tightening for spindle
Possible causes:
(1) Misalignment for tool tightening.
(2) Tool shank is rusty or with rust and foreign matter.
(3) Damage or no signal of solenoid valve for tool tightening.
(4) Problem with signal for tool tightening of spindle.
(5) Problem with spindle.
Solution:
(1) Adjust the position of screws for tool magazine to make the tool shank at the center of the spindle
for tool tightening. Adjust the position of 2 nd reference point for Z-axis in the system.
(2) Remove the rust and foreign matter on the tool shank.
(3) Measure the signal line of solenoid valve for tool change or replace the solenoid valve.
(4) Adjust the location of signal for tool tightening of spindle, check whether the I board of system is
damaged, whether poor contact or short circuit exists in the signal line.
(5) Return the spindle to factory for maintenance.

5. Insufficient air pressure
Possible causes:
(1) Check air pressure.
(2) Air pressure switch is damaged.
(3) Poor contact or breaking of signal line for air pressure switch or the I board of system is damaged.
Solution:
(1) Check whether air compressor is in operation and check its pressure.
(2) Replace the air pressure switch.
(3) Find out whether signal line for air pressure switch is loose and replace the signal line and board of system.

6.Overcut during cutting
Possible causes:
Jinan Quick-Fulltek CNC Machinery Co., Ltd.
63
(1) Gear clearance.
(2) Reducer clearance.
Solution:
(1)Adjust the gear clearance.
(2) Replace the reducer.

7. Damage of sliding block
Possible causes:
(1) Lack of oil.
(2) Collision between sliding block and hard object.
Solution:
(1) Lubricate the sliding block and pay attention to whether the oil pipe is blocked.
(2) Replace the sliding block.

9.Non-rotation of vacuum pump
Possible causes:
(1) The thermal overload relay is overloaded.
(2) Power off or unstable voltage of vacuum pump.
(3) Phase loss for the power supply of vacuum pump.
(4) Burnout of motor or damage and seizure of rotor bearing.
Solution:
(1)Adjust the current of the thermal overload relay to an appropriate value while ensuring safety.
(2) Check the power switch of the pump or install voltage stabilizer.
(3) If one phase is lost, the pump body will heat up rapidly, so the power must be cut off immediately
and the circuit should be checked.
(4) Repair the coil or replace the rotor.
