The maintenance and matters needing attention of the double-column CNC vertical lathe mainly include the following aspects:

Maintenance:

1. Equipment lubrication: When the double-column CNC vertical lathe is running, lubricating oil needs to be used internally to ensure its accuracy and life. Therefore, the oil holes of the double-column CNC vertical lathe should be cleaned regularly to ensure smooth flow and filled with lubricating oil. At the same time, each guide rail surface and sliding surface of the double-column CNC vertical lathe as well as each screw rod also need to be filled with lubricating oil. In addition, double-column CNC vertical lathes must regularly check the oil level of the transmission mechanism oil tank and refuel to the elevated position in time. The speed change handle of the double-column CNC vertical lathe spindle box needs to be in the correct position before starting, and then test the machine, and the speed should be gradually adjusted from low to high.

2. Cleaning and maintenance: The double-column CNC vertical lathe should be kept clean, including the shell of the equipment and its various parts. It needs to be wiped frequently with a soft cloth, and debris that may remain on the surface of the equipment should be cleaned in time. The cleaning and lubrication of the bed guide surface and the middle slide guide surface also require regular inspection and maintenance. The start and stop handle of the double-column CNC vertical lathe workbench can only be pulled by hand, and pedals are strictly prohibited. After the processing is completed, it is necessary to clean up the iron chips and other debris, and wipe all parts of the machine.

3. Inspection and replacement: Key components such as the double-column CNC vertical lathe spindle, bearings, and bushings need to be inspected and replaced regularly to ensure the stability and durability of the equipment. At the same time, it is necessary to clean up waste oil in time, check the status of machine tool lubricating oil and coolant, and add or replace them in time.

Precautions:

1. Safe operation: When using a double-column CNC vertical lathe, you must abide by safe operating procedures and wear labor protection supplies correctly to avoid personal injury caused by misoperation. The rough surface of the workpiece is not allowed to be placed directly on the workbench and should be supported by horns or screw tops; it is strictly prohibited to use the workbench for other operations, such as hammering to correct the workpiece, welding the workpiece, etc.

2. Equipment preheating and lubrication: Before operating the double-column CNC vertical lathe, it is necessary to preheat and lubricate the equipment and check whether each component and related accessories are normal.

3. Dust prevention and cleaning: For double-column CNC vertical lathes, attention should be paid to preventing dust from entering the electronic control device, so as to prevent floating dust and metal powder from causing a decrease in the insulation resistance between electrical components, resulting in failure. In addition, after using the equipment, the machine tool and the environment need to be kept clean.

To sum up, the maintenance and precautions for double-column CNC vertical lathes involve many aspects such as equipment lubrication, cleaning, inspection and replacement of key components, and safe operation. By strictly implementing these measures, you can ensure the normal operation of the equipment, extend its service life, and improve processing accuracy and efficiency.
