Daily cleaning and maintenance of CNC lathe processing

For the personal safety of operators during cleaning and maintenance, we must cut off the power supply when processing and maintaining CNC lathes, and then perform cleaning and maintenance according to the following steps. This is one of the reasons why CNC lathe processing has been widely used in the field of machining in recent years.

In general maintenance of CNC lathes, we all use lubricating oil, so the lubricating oils suitable for CNC lathe processing and maintenance generally include: oiling lubrication, splashing oil Lubrication, oil rope guide oil lubrication, marble oil cup lubrication, butter cup lubrication, oil pump oil lubrication, etc. Parts in the headstock are lubricated by oil pump circulation or splash lubrication. The lubricating oil in the box is generally replaced every three months. There is an oil window on the main shaft body. If it is found that there is no oil output in the oil window, it means that the oil pump oil delivery system is faulty. Stop immediately to check the reason for the oil cut off, and the lathe can only be started after the repair. In addition to the gear splash lubrication, the gears and bearings in the feed box also have an oil storage tank lubricated with oil ropes on the feed box. The oil storage tank should be filled with oil once per shift. Swap gearbox intermediate gear shaft bearings are grease cup lubricated once per shift. The bed rails and slide rails should be cleaned and refueled with an oil gun before and after work.

Let's take a look at the seven steps of CNC lathe processing:

The first step of daily cleaning and maintenance of CNC lathe processing

After completing the processing tasks every day, cut off the power supply, and make sure that the surface of the lathe, each cover, each guide rail surface, the lead screw, and the smooth bar are free of oil stains, iron filings, and the surface of the lathe is clean.

The second step of daily cleaning and maintenance of cnc lathe processing

After completing the processing tasks every week, it is necessary to maintain the guide surface and center of the bed. Cleaning and lubrication of slide rail surfaces. Usually, when the CNC lathe has been running for 500 hours, it needs to be maintained at the first level. The maintenance work is mainly carried out by the operators, with the cooperation of the maintenance personnel. Follow the following order and requirements:

First, carry out the maintenance of the spindle:

1. Clean the oil filter to make it free of debris;

2. Check whether the spindle lock nut is loose, and whether the set screw is tightened;

3. Adjust the brake and clutch friction plate clearance.

Secondly, the maintenance of the exchange gear box:

1. Clean the gears and bushings, and inject new grease into the oil cup;

2. Adjust the gears The meshing clearance;

3. Check whether the shaft sleeve shakes.

The third step of daily cleaning and maintenance of cnc lathe processing

Maintenance of skateboards and tool holders.

The fourth step of daily cleaning and maintenance of cnc lathe processing

Maintenance of tailstock: by wiping the surface and adding oil to lubricate, Tailstock for maintenance.

The fifth step of daily cleaning and maintenance of cnc lathe processing

Maintenance of lubrication system:

1. Cleaning Cooling pump and oil filter;

2. Ensure that the oil passage is smooth;

3. Check the oil quality and keep it in good condition. (The goal is to ensure that the oil standard is clear)

The sixth step of daily cleaning and maintenance of cnc lathe processing

Maintenance of electrical appliances:

1. Clean the dust on the motor and electrical box;

2. The electrical devices are fixed neatly.

The seventh step of daily cleaning and maintenance of CNC lathe processing

Exterior maintenance:

1. Cleaning CNC The surface and cover of the lathe should be kept clean inside and outside, without rust and oil;

2. Check and make up the screws and handles. After cleaning and wiping, all parts are lubricated as necessary.
