Does the CNC engraving machine need to be adjusted after a period of use?

Any machine will have certain errors after being used for a period of time, and CNC engraving machines are no exception. Therefore, it is necessary to adjust the machine equipment regularly to ensure the accuracy. So how to adjust it?

CNC Engraving Machine

The specific adjustment method of CNC cutting machine:

1. Adjustment of the conveyor belt of the cutting machine

First start the cutting machine, and the worktable can be lifted to contact the abrasive belt. Conveyor belt grinding should not exceed 0.1mm at a time to avoid deformation of the conveyor belt. After adjustments, clean up wear debris and adjust the thickness setting to zero.

2. Adjustment of gauge roll

Adjust the height of the workbench. After the abrasive belt is removed, put the 60-80# sandpaper template on the surface of the conveyor belt, lift the worktable, make the sandpaper lightly touch the roller, and move the template back and forth. After adjustment, remove the chip and set it to zero.

3. Adjustment of pressure roller

Raise the sanding pad, remove the abrasive belt, raise the working table, lightly touch the conveyor belt with the gauge roller, then adjust the working table according to the thickness display reading until the pressure roller touches the conveyor belt lightly and tighten the nut.

4. Belt swing adjustment

Controlled by a photoelectric switch, the swing reference can be changed by adjusting the position of the abrasive belt. Generally speaking, the protective fiber of the sanding belt is about 1cm away from the edge of the rod, which is controlled by two pairs of photoelectric cells. The datum is at the edge of the rod and stops at this location.

5. Sand pad leveling

Raise the sanding pad, remove the sanding belt, place the level on the conveyor belt, raise the table until the gauge roll lightly touches the level, move the level from one end of the sanding pad to the other, and check the level of the sanding pad If there is an error, adjust it through the left and right threads of the sanding pad.

6. The display returns to zero

The CNC cutting machine has been zeroed before leaving the factory. After adjusting the flatness of the table, grinding the conveyor belt and calibrating roller, the thickness digital display needs to be reset to zero.

The emergence of CNC cutting machine has improved the production efficiency and processing quality of panel furniture. However, it is a kind of numerical control equipment, and after a long time of operation, errors will inevitably appear. Therefore, readjustment is required to ensure long-term use.
