Analysis and Solution of the Broken Knife of Woodworking cnc router machine

  In many furniture factories, many woodworking cnc router machines are turned around all day long. It is inevitable to work overtime if there is a large demand for orders. In this case, it is often difficult for workers to spare time to maintain and inspect the machine. , Occasionally there will be various failures, such as the situation where the cnc router machine breaks the knife, how to continue engraving?

  Next, let’s take a look at what to do if the carving knife of the woodworking cnc router machine breaks, and how to continue carving after the carving machine breaks the knife!

  There are several reasons for broken knife:

  1. The spindle motor is not perpendicular to the table. The manufacturer says that your knife is not tightened. It makes sense, but if they only give you such a statement, it must be fooling you.

  2. The knife is not good, and the chips cannot be removed smoothly. They are all entangled in the knife, and the knife must be broken. Don't think that if the knife is bought from the manufacturer, there will be no problems.

  If there are other people who use the same machine and the same knife as you, and you keep breaking, then the first situation is mainly considered.

  3. The spindle speed and feed speed are not suitable and the tool will break. This situation is easy to judge, and it should be cut off as soon as it comes up, and it would be cut off when doing other work.

  4. Uneven material will break the knife.

  There are two main types of knife breaks in woodworking cnc router machines:

  The first type: For long-time engraving of high-hardness materials, tool wear and blade breakage are inevitable. If the tool is worn out, the engraving depth must not meet the set requirements;

  The second type: the tool has broken edge, how to ensure that the tool is the same height twice with a new one, and how to continue carving, these are very real problems.

  These two common phenomena can be classified as one problem. It can be understood that the condition of severe tool wear is equivalent to the broken blade state. We can deal with it in the same way.

  When we find that the tool is suddenly broken during the operation of the woodworking cnc router machine, please pause or stop the operation in time. Then make a note of the current block number, which will be used later. After the spindle is completely stopped, replace with a new tool. Because we are manually changing the tool, this will inevitably cause the height of the Z direction to change. We only need to use the tool setting block to re-determine the Z direction origin.

  There is no change in the X and Y directions, so we don’t have to worry about it. After confirming, we find the "advanced start" function under the operation menu. The dialog box asks us to enter the start line segment number. This segment number is the number we wrote down when we started to stop the machine. We need to enter the start break number The number is smaller than the number written down, and the specific number depends on the time we found the knife. If it is found late, subtract some more numbers. The end segment number defaults to the end of the file. In this way, the woodworking cnc router machine can automatically continue to engrave the unfinished parts.
