A
One: Zero point return
The machine moves all axes in full stroke, so that the surface of the lead screw and guide rail is fully covered with grease, and then the X/Y/Z/A/B axis stops at the zero point. The turret, tool magazine, and worktable stop at position 1, and the tailstock and robot arm stop at the zero point.

Two: Spindle cleaning
Do not leave the tool holder in the spindle, and avoid residual cutting fluid on the conical surface of the spindle and tool holder. After removing the tool holder, clean the spindle conical surface. Apply anti-rust oil to the tool holder and spindle conical surface.

Three: Moisture and rust prevention
The surface of the worktable and the fixture will rust, so apply anti-rust oil and grease.

Four: Battery confirmation
Confirm whether the voltage of all batteries in the machine is low. When restarting after a long power outage, the processing program, machine parameters, and the zero point of each axis may be lost. Please replace the battery regularly. Implement it one week before long-term shutdown to confirm that the battery is inserted correctly and the contact is good.
V. Data backup
If you are worried about the loss of processing programs, machine tool parameters and other data, please back up important information to a computer or USB flash drive.
VI. Iron chip cleaning
Clean the chips in the processing area of ​​the machine.
VII. Cutting fluid maintenance
Remove iron chips and impurities from the cutting fluid, and add bactericidal preservatives to prevent the cutting fluid from deteriorating and becoming ineffective.
VIII. Cut off power and gas
Cut off the external power supply of the machine tool, close the gas valve, and turn off the water source.

A — 1 —Maintaining machining accuracy
Check whether the oil circuit is unobstructed. Under low temperature conditions, the viscosity of the lubricating oil of the screw and wire gauge increases. Confirm that the lubricating oil can fully enter the lubrication position of key components such as the wire gauge and screw.
After starting the machine, it must be preheated for about 10 minutes before processing. The preheating time should be extended for machines that have not been used for a long time.
Before shutting down, turn the turret to the No. 1 tool position, return the X and Z axes to the origin position (the machining center moves the three-axis stroke to the middle position of each axis stroke), and press the emergency stop button.
Operation steps for switching on and off the machine:
.
Starting: Turn on the main circuit breaker power supply-press the green power-on button-release the emergency stop button-press the reset button, and the machine tool starts.
.
Shutdown: The turret turns to No. 1 position, the X\Z axis returns to zero-press the emergency stop button-disconnect the main circuit breaker power supply (for special fixtures, equipment that is clamped by the fixture after the machine tool is powered off, the fixture must clamp the workpiece before shutting down).
Keep the machine tool dry and clean.

— 2 —Maintenance and inspection
I. Daily maintenance and maintenance
Check the lubricating oil level to ensure the lubrication of the machine tool.
Check whether there is enough hydraulic oil in the hydraulic oil tank. If not, add it in time.
Check the oil level of the pneumatic triplex, which is about 2/3 of the entire oil pipe height. Every day, drain the water vapor in the pneumatic triplex oil filter tank through the drainage switch.
.
For equipment using pneumatic components or air-cooled electric spindle equipment, check the air pressure, loosen the adjustment knob, and adjust the pressure according to the principle of right-hand increase and left-hand decrease. It is generally set to 5-7KG/CM~2. The pressure switch is usually set to 5KG/CM~2. When it is lower than 5KG/CM~2, the alarm will sound, and the system will sound the "low air pressure" alarm. After the pressure increases, the alarm message disappears.
For equipment with spindle air blowing, check whether the air blowing of the inner cone of the spindle is normal, wipe the inner cone of the spindle with a clean cotton cloth, and spray light oil.
Clean the iron filings in the chuck, open and close the chuck, and confirm whether the action is normal.
Clean the exposed limit switches and bumpers.
Check all signal lights and abnormal warning lights to see if they are normal.
Check whether the hydraulic unit pipe has leakage.
Clean and sweep the machine after daily work.
Keep the environment around the machine clean.
2. Weekly maintenance
Clean the air filter of the heat exchanger, the cooling pump, and the lubricating oil pump filter.
Check whether the turret press screw is loose.
Check whether the turret center is offset.
Check whether the turret changes the tool smoothly, the tool changes without shaking, and whether the locking sound is normal.
If there is an oil cooler, check the oil cooler oil. If it is below the scale line, please add oil cooler oil in time.
Confirm whether the chuck is clamped or not, and fill the chuck with oil.
Clean the drainage hole under the front end cover of the spindle.
3. Monthly maintenance
Check the lubrication of the X, Y, and Z axis tracks. The track surface must be well lubricated.
Check and clean the limit switch and the bumper.
Check whether the oil in the oil cup of the knife cylinder is sufficient, and add it in time if it is insufficient.
Check whether the signs and warning nameplates on the machine are clear and exist.
Clean the water tank and remove the iron chips and impurities deposited at the bottom of the water tank.
4. Half-year maintenance
Disassemble the three-axis anti-chip shield, clean the three-axis oil pipe joints, ball screws, and three-axis limit switches, and check whether they are normal. Check whether the hard rail scraper of each axis is in good effect
Check whether the servo motor and head of each axis are running normally and whether there are any abnormal sounds.
Clean the filter of the hydraulic station and replace the oil of the hydraulic unit.
Comprehensively check whether all contacts, joints, sockets, and switches are normal.
Clean the dust in the electrical box (make sure the machine tool is in the off state).
Confirm whether there are any abnormal sounds and interferences in the moving parts of the machine tool guard plate, and adjust them in time.
Use a level to confirm whether the machine tool is level and twisted within the standard range.
5. Annual maintenance
Check whether all buttons are sensitive and normal.
Clean the cutting fluid water tank and replace the cutting fluid.
Check the vertical accuracy of each axis to determine whether adjustment is required.
Check whether the lubricating oil pipe is flattened or damaged, and replace it in time.

— 3—Maintenance and repair
I. Daily maintenance and repair
Note: Equipment maintenance and repair should be performed by professional engineers.
The grounding protection system should have intact continuity to ensure personal safety.
Regularly check components such as circuit breakers, contactors, single-phase or three-phase arc extinguishers. If the wiring is loose or the noise is too loud, find out the cause and eliminate the hidden dangers.
Ensure that the cooling fan in the electric cabinet operates normally, otherwise it may cause damage to the components.
If the fuse is blown and the air switch trips frequently, the cause should be found and eliminated in time.
The data of the absolute control system is maintained by the servo drive battery. When the battery voltage is too low (warning 9F), the drive battery needs to be replaced. Please order a battery unit of the same model as soon as possible and keep the drive power on. Please turn on the power of the drive unit 30 minutes before replacing the battery, and complete the battery replacement within 1 hour.
.
2. Battery replacement steps
Confirm that the input power has been cut off and the power of the replaced drive unit has been turned off.
Unplug the battery plug connected to the battery socket of the drive unit.
Press the side of the battery with your fingertips, push the battery horizontally and remove it.
Connect the plug of the new battery to the battery socket of the drive unit.
Install the battery on the drive unit.
