Inquire

In the process of using woodworking engraving machine to process and produce, sometimes there will be knife breaks. Broken knife not only affects the quality of the product, but also affects the production cycle and efficiency of the product, and directly increases the cost of the tool. So, why does the woodworking engraving machine break the knife when it is working? How to solve this problem? Leapion laser shares are as follows:

First of all, why does the woodworking engraving machine break the knife when it is working?

1. The strength and hardness of the tool are not enough, which is mainly related to the material and geometric angle of the tool.

2. The sharpness of the tool is insufficient, mainly because the tool is not well ground.

3. The protruding length of the tool. Excessive protruding length of the tool will easily cause the tool to break.

4. The hardness of the processed material is too high or there are impurities in the processed material, engraving high-hardness materials for a long time, resulting in tool wear.

5. The slow speed of the spindle motor will cause the tool to break.

This is because a slow speed will cause the amount of tool to be eaten per tooth per revolution to increase, and the cutting force will increase, resulting in tool breakage.

6. In the state of woodworking tool clamping, the tool is not properly clamped, the radial runout is large, or the depth of the tool is too long, which may cause the tool to break.

7. Whether the processing procedure is correct and reasonable directly affects whether the tool will break. If the processing procedure itself is a break procedure, the subsequent processing cannot be carried out.

8. If the tool has not been changed for a long time, the hardness, strength, and sharpness of the tool itself will be greatly compromised. If the acceleration is not well controlled, then the tool will be broken naturally.

9. Improper operation. The level of the operator of the machine tool determines the behavior of the operator of the machine tool.

So, how to solve the problem of broken knife when woodworking engraving machine is working?

1. When you find that the tool is suddenly broken during the operation of the engraving machine, please pause or stop the operation in time.

2. Then remember the current block number, this number will be used later.

3. After the spindle is completely stopped, replace with a new tool, because it is basically a manual tool, which will inevitably lead to a change in height in a certain direction. At this time, you only need to use the tool setting block to re-determine the origin of the direction. 

4. After confirming, find the "advanced start" function under the operation menu. The dialog box asks to enter the starting line segment number. This segment number is the number that was written down when the machine was stopped at the beginning. The number is smaller, and the specific number depends on the time when the knife was discovered.

5. If it is found late, subtract some more numbers. The end segment number defaults to the end of the file. In this way, the CNC woodworking engraving machine can automatically continue engraving the unfinished parts.

6. Other matters needing attention:

1) Reasonably set the processing parameters and cutting amount of the woodworking engraving machine.

2) When engraving different materials, you need to set different engraving parameters and use different tools according to different materials.

3) Choose an appropriate lubricant for lubrication.
