8 Tips for Daily CNC Router Machine Maintenance

8 Tips for Daily CNC Router Machine Maintenance

Purchasing a CNC router machine is an important decision and large investment for a

woodshop. CNC machine is the life of the factory. If a machine breaks down, it will waste time

and cost, and bring direct losses to the manufacturers. So the routine maintenance of the

machines should not be overlooked. It is very imperative to keep your machine uptime and

productivity. Proper use and maintenance of CNC machines can prevent machinery failures and

greatly prolong the machine’s life. And if the machine is well maintained, which can keep the

machine in good work condition and stability, so the processing speed and accuracy can be well

guaranteed. Daily maintenance is not time-consuming. On the contrary, it can reduce time and

cost.Here are 8 tips of CNC router maintenance we sort out to keep the CNC machines at your

woodshop running run properly.

1. Maintain a good external environment for the machine

(1) Ensure the temperature of the operating workshop, especially in the winter, it is better to let

the machine to reach room temperature.

(2) Check the applicable temperature of the fueling standard, at least to the minimum

temperature.(3) When the machine is not in use, if the room temperature is lower, the water in the tank

should be poured out to prevent cracking of water tanks and water pipes. Although the

influence of temperature on the CNC router machine is not very big, because many operators

add butter to the screw and forget to clean up in winter, which makes the machine hard to run

when it starts up. The temperature in some workrooms is very low. Although the oil is added, it

can still be frozen.

(4) The humidity in the operation room should not be too high, otherwise, the electrical

accessories of the machine are easy to worn out.

(5) CNC router machines cannot be installed in places with high humidity, dust, and pollution,

otherwise, the performance of electronic components may be degraded and will cause poor

electrical contact or short circuit faults. So if the environment of the CNC machine is not good,

it will directly affect the normal operation of the machine.

(6) Electromagnetic interference in the operation room must be noted, if the interference is too

large, it is easy to affect the machining accuracy. And it should be kept away from the

equipment with high vibration to avoid interference.

2. Keep the CNC machine clean

(1) Every time the work is done, sweep and clean the table in time. Blow away the dust on the

machine with an air gun! A lack of cleaning could lead to a buildup of dirt and debris. Besides,some debris can get into the lubrication system, so that stop the machine from working. Wiping

down your machine daily will also keep the wood chips from building up in damage.

(2) Clean up the chips around the guide rail and the linear bearing guide blocks to prevent

the machine from jamming due to debris interference when it is running.

(3) Regularly clean the lead screw to prevent foreign objects from sticking on the lead screw.

The screw is very important in the equipment. It determines the accuracy of the machine and

also it plays an important role in the transmission process.

(4) Clean the industrial control box regularly, dust is the biggest killer of the circuit board. When

the board is too dirty, it may cause a short-circuit fault. After each use of the machine, pay

attention to cleaning, be sure to clean the dust on the platform and the transmission system.

(5) Filters should be checked and cleaned on a regular basis and replaced if necessary. When

the filter is too dirty, there may be cause poor heat dissipation and malfunction.

(6) Cleaning your tool holders and collets and spindles are also important. They must be

rustproof and clean.

(7) Check the surface of the spindle. You can wipe it with a clean soft cloth.

3. Regular lubrication

CNC machines need to be regularly lubricated to function properly and prevent premature wear.

Each of these components such as the spindles, the lead screws, the guide rails, bearings, toolholder and sliders require regular and correct lubrication to slow down the wear speed. Please

be sure to follow the manufacturer’s recommendations and use grease or oil. Improper

lubrication can lead to machine parts sticking or not moving as smoothly as they should and

even cause more serious problems.

(1)First, clean the guide rails and lead screws. Use a rag to clean the oil and material debris on

the guide rails and the lead screws. If the temperature is low, add oil to the rails and lead

screws, preferably antifreeze oil.

(2)The refueling cycle is twice a month.

(3)If the machine is not used for a long time, it should be refueled regularly to ensure the

flexibility of the transmission system.

(4)After the oil is added, move slowly back and forth to ensure that lubricating oil can be evenly

applied to the guide rail and the lead screw.

(5)Regular (weekly) lubrication of the transmission system (X, Y, Z three axes).

4. Check your computer regularly

Computer abnormalities can also cause a lot of problems, especially for the computer

connected to a CNC router machine.

(1) Clean the dust of the chassis regularly, pay attention to the heat dissipation of the chassis,

and be careful that the industrial control card is faulty due to excessive dust.

(2) Regularly defragment the disk and optimize the computer system.

(3) Regularly check and kill the virus.
