How to maintain the Woodworking CNC Router and the cause of blade breakage?

How to maintain？

After using the machine for a long time, it will make a touch sound, slightly sharp metal friction sound when turned on, and the ventilation holes will accumulate piles of wood chips. At this time, maintenance should be carried out.

1 means of preparation

1. Flat screwdriver

2. Cross screwdriver

3. Pointed nose pliers

4. Universal needle car oil (available in hardware stores)

5. Small brush

II Maintenance steps

1. Unplug the power cord. Safety first.

2. Remove the plastic sheath, take a cross screwdriver counterclockwise, and loosen the two screws.

3. Take a screwdriver and unscrew the left and right pairs of carbon brush screws counterclockwise. Use pointed pliers to remove the carbon brush, carefully note the installation position of the carbon brush, and restore it smoothly.

4. Clean the dust on the carbon brush with a brush. Gently spray when there is an air spray gun.

5. Slightly apply force to pry open the outer shell.

6. Rotate the Mada shaft with your fingers to see if there is any sound of touching or metal friction.

7. Make sure there is no dust left, use universal needle turning oil, drop a little into the seam on the circular ring, and rotate the shaft with your fingers to ensure that the oil is absorbed.

8. Wipe off the remaining oil, otherwise dust will come on in the future.

9. Follow the above steps to restore the device.

10. After tightening the screws, first rotate them with your fingers to see if they are smooth and if the carbon brush is properly installed, and make sure there are no abnormalities.

11. Plug in the power and turn it on until the sound is normal!

Reason for blade breakage

1. Processing program

The machining program is the instruction for engraving processing, which includes position and speed instructions, and is the basis for machine tool movement. Therefore, whether the machining program is correct and reasonable directly affects whether the tool will break.

2. The machine tool itself

The engraving machine is the executor of engraving processing and also the provider of engraving power. Whether the engraving machine is selected correctly during processing and whether the current state of the engraving machine is normal will become the influencing factors of tool breakage.

3. Cutting tools

The clamping state of carving machine tools is also a factor affecting tool breakage, such as uneven tool clamping, large radial runout, or too long deep tool length, which may cause tool breakage.

4. Materials

Carving materials are processed objects, and if the material itself has uneven hardness and impurities, it can cause tool breakage.

5. Workpiece clamping

If the workpiece is not clamped firmly or securely, it can cause tool breakage.

6. Cutting fluid

It shows obvious performance when processing hard metals.

7. Surrounding environment

For example, having vibration sources around can affect the processing status and cause tool breakage. Unstable voltage or exceeding the working range of the engraving machine can also cause abnormal working conditions of the machine tool and cause tool breakage.
