The daily maintenance specifications of CNC machining centers mainly include the following aspects:
1. Inspection and preparation before commissioning
Wear occupational protection equipment to ensure personal safety.
Lubrication and maintenance: Check the oil level of each lubricant to ensure lubrication of the machine tool.
Check whether all parts of the machine tool are intact, including the control panel, spindle taper hole, tool carriage, tool magazine arm and tool magazine, etc., to make sure there are no damaged or missing parts.
2. Precautions during treatment
When clamping parts, handle them carefully to avoid damage to the work surface. When the workpiece is heavy, it is necessary to check the bearing capacity of the machine tool table to ensure that it is not overloaded.
The processing program should be checked before running it. When using the high-speed function, tool matching must be confirmed to ensure the stability of the machining process.
After starting the machine tool, check whether the movement of the spindle and worktable in all directions is normal, and monitor whether there are abnormal noises, etc.
During processing, you should always check whether the movement and processing status of the machine tool are normal. When you encounter abnormal phenomena, noises and alarms, you should immediately stop the machine for inspection and treatment, and continue treatment only after the fault. is eliminated.
3. Daily cleaning and maintenance
Perform a complete cleaning of the machine tool, including the operation panel, spindle taper hole, tool carriage, tool magazine arm and tool magazine, etc., to ensure that There is no more dust or iron filings left.
Check whether there is sufficient coolant in the coolant reservoir, add it in time if it is insufficient, and ensure that the coolant is clean to avoid the accumulation of impurities and dirt. bacteria.
Check whether the air pressure is normal and ensure the stable operation of the machine tool pneumatic system.
Check whether the air blowing to the inner cone hole of the spindle is normal, wipe the inner cone hole of the spindle with a clean cotton cloth, and spray light oil on it to keep it lubricated and clean.
Clean the tool magazine arm and the tool, especially the claw part, to prevent dust and debris from affecting the use of the tool.
Check whether all abnormal indicator lights and warning lights are normal so that potential problems can be discovered and dealt with in a timely manner.
Check whether there is leakage in the tube of the hydraulic unit to ensure the stable operation of the hydraulic system of the machine tool.
4. Environmental maintenance
After the daily work of the machine tool is completed, cleaning work should be carried out to keep the interior and exterior of the machine tool clean.
Keep the environment around the machine clean and tidy to prevent the entry of dust and debris to reduce damage to the machine tool.
5. Periodic maintenance
In addition to daily maintenance work, the CNC machining center also needs to be regularly maintained, such as weekly cleaning of heat exchanger air filter, cooling pump, lubricating oil pump filter, etc. . In addition, a maintenance plan should be developed in accordance with the manufacturer’s requirements, and all parts of the machine tool should be inspected, cleaned, lubricated and adjusted regularly to ensure the stable operation and processing accuracy of the machine tool . To summarize, the specifications of daily maintenance operations of CNC machining centers cover many aspects such as inspection and preparation before start-up, precautions during processing, daily cleaning and maintenance, environmental maintenance and periodic maintenance. By strictly implementing these specifications, the stable operation and efficient processing of CNC machining centers can be ensured, their service life can be extended, and the processing precision and product quality can be improved.
