How to maintain and clean the lubrication system of a radial drilling machine?

The maintenance of the lubrication system of the radial drilling machine should be carried out in accordance with the specifications for different cycles and different parts. The specific details are as follows:

Ⅰ. Basic checks before daily startup

Oil level check ‌ : Inspect the oil gauges on the spindle box, feed box, guide rails and other parts to ensure that the oil quantity is within the standard scale range. If insufficient, add lubricating oil of the same brand.

Visual inspection ‌ : Check whether all oil cups, nozzles and oil pipes are complete and in good condition, without any damage or leakage.

Oil circuit unblocking ‌ : Clean the iron filings and debris from the oil cup mouth to ensure that the lubricating oil can flow smoothly into the lubrication points.

Ⅱ. Specialized maintenance for different lubrication points

Centralized lubrication system ‌ : Regularly check the pressure of the manual/automatic lubrication pump, clean the pump body filter to prevent iron filings from blocking the oil passage, and ensure that the lubricating oil can be synchronously delivered to the spindle box and gearbox.

Dispersed lubrication parts ‌ : Regularly add high-temperature resistant lubricating oil to the main shaft and bearings; The gear oil in the gearbox should be replaced periodically. The columns and rocker arm guide rails should be lubricated with special grease using a grease gun. The lead screw and pin shaft should be lubricated with oil as needed.

clogging point cleaning ‌ : Clear each independent lubrication point one by one to prevent individual components from getting stuck, overheating and wearing due to insufficient oil supply.

Ⅲ. Key Points for Regular and In-depth Maintenance

Oil quality control ‌ : Regularly take samples to check the condition of the lubricating oil. If the oil is turbid, has an odd smell or is mixed with impurities or water, immediately replace it with new oil and clean the oil tank at the same time.

Pipeline unblocking ‌ : Clean the oil felt and oil filter screen every week, and thoroughly unblock the lubrication pipelines every quarter to completely remove the accumulated iron filings and debris inside.

Fault detection ‌ : If there is no pressure in the lubrication system, abnormal noise or overheating of components, repair the lubrication pump in time. Replace the severely worn pump body directly.

Ⅳ. Maintaining taboos

It is strictly prohibited to mix lubricating oils and greases of different grades to prevent the oil from deteriorating and becoming ineffective.

Excessive oil injection is prohibited to prevent accumulated oil from seeping into the electrical system and causing short-circuit hazards.

It is prohibited to fail to clean the oil circuit for a long time to prevent impurities from entering the precision components and causing irreversible wear.

The cleaning of the lubrication system of the radial drilling machine can be carried out in accordance with the following standard steps:

Ⅰ. Preparations Before Cleaning

Prepare in advance the same model of cleaning oil, clean brushes, dust-free cloths, oil collection containers, and new oil filters, oil felt and other replacement parts.

Cut off the main power supply of the equipment and place an oil collection container under the lubrication system to prevent waste oil leakage and pollution of the workshop environment.

Mark the connection positions of each oil pipe and oil cup properly to prevent resetting errors after disassembly.

Ⅱ. Step-by-step cleaning operation

Drain the old oil ‌ : Open the oil drain valves of the oil tank, spindle box and feed box, completely drain the old lubricating oil in the system, and clean the iron filings, oil sludge and other impurities accumulated at the bottom of the oil tank.

Disassemble and clean components ‌ : Remove all oil cups, oil felt, and oil filter screens. Rinse repeatedly with cleaning oil. Use a brush to clean stubborn oil stains in the crevices. After rinsing, dry with a lint-free cloth.

Unclog pipelines ‌ : Inject the cleaning oil into the lubrication pump, start the lubrication pump to circulate and flush all oil circuits. Repeat the flushing 2-3 times until there are no obvious impurities in the oil flowing out of the pipelines.

Clean the interior of the box ‌ : Open the maintenance covers of the gearbox and spindle box, wipe the inner walls of the box with cleaning oil to remove the remaining oil sludge and metal debris. After confirming that there are no residual impurities on the inner walls, dry them.

Ⅲ. Finishing operations after cleaning

Reset all oil pipes, oil cups, oil filters and oil felt according to the marks, and check that all connection parts are not loose or leaking.

Add new lubricating oil of the right grade to the system, and control the oil level at 1/2 to 2/3 of the oil window.

Power on and test run the lubrication pump to ensure that oil flows out normally from all lubrication points, and there is no blockage or leakage in the oil passage.

Ⅳ. Cleaning Precautions

Open flames are strictly prohibited throughout the cleaning process to avoid potential safety hazards caused by the cleaning oil.

Used oils of different grades should be collected separately and treated in accordance with hazardous waste standards. They must not be dumped at will.

After the cleaning is completed, keep a maintenance record and mark the time node for the next lubrication system cleaning.
