Analysis of the reasons for the running board of the CNC cutting machine (1)

Today, Superstar CNC will help you analyze the reasons for the cutting machine running board, hoping to let everyone avoid the CNC wood cutting machine running board.

1. The adsorption force of the machine itself is not good, the problem of adsorption and fixation of the whole board is not big, and it cannot be adsorbed when processing small materials.

2. The processing path generated by the production software is unreasonable. It should follow the principle of cutting the small board first and then cutting the large board, first cutting the unconnected place and then cutting the connected place. All the small boards should be cut from the outside to the inside, following the principle of order. That is, the product does not rely on its own adsorption force to fix itself, but relies on other boards to assist in fixing. Note: When processing solid wood, special attention should be paid to the texture of the material.

3.After processing, the cleaning is not in place. There are small debris on the table surface, which causes no effective contact between the product and the floor. Air leakage affects the relative friction and causes the running board.

4. The amount of overcut of the tool during processing is too large, and the tool marks of different depths left by the machining of the table bottom plate will leak air during the machining of the tool marks, resulting in a small adsorption force between the material and the bottom plate, and at the same time reducing the small contact area of the contact surface. , the positive pressure decreases, then the corresponding friction force will also decrease accordingly. Under the condition that the cutting resistance remains unchanged, the friction force is less than the resistance, which will cause the running board.

5. Whether the negative pressure of the vacuum pump itself can reach the required value, this can be seen by closing the adsorption valve to see the value of the vacuum pressure gauge. The normal individual test should reach -0.7-1.2. Adsorption fully open should also be controlled above -0.5, too low adsorption force is not enough.

6. Check the air leakage at the connection between the adsorption table and the vacuum pump, and whether there is air leakage at the edge of the bottom plate. Switch on and off an adsorption zone separately to test how the suction is.

7. If it is in a relatively high altitude area,it is recommended to use a vacuum pump with a higher power.

8. Whether the structure of the countertop is reasonable determines the vacuum adsorption effect. For vacuum pumps with the same power, the adsorption effect of different specifications of the table is different.

These are the reasons for the CNC cutting machine running board. The next issue of Superstar CNC will give you an article on how to solve the cutting machine running board.
