Broken knife for cnc router machine

Broken knife for cnc router machine

1. Processing procedures

Machining program is the instruction of engraving processing, which contains position instruction and speed instruction, and is the basis of machine tool movement, so whether the machining program is correct and reasonable directly affects whether the tool will break the tool or not.

2. The machine tool itself

Engraving machine is not only the executor of engraving processing, but also the provider of engraving power. Whether the engraving machine is selected correctly and whether the current state of engraving machine is normal or not will become the influencing factors of cutting knife.

3, cutting tool

The clamping state of the cutting tool of the engraving machine is also an influencing factor of the broken knife, such as the tool clamping is not neat, the radial runout is large, or the length of the tool depth is too long, which may cause the broken knife.

4. Materials

Engraving material is processed object, if the hardness of the material itself is uneven, there are impurities will cause broken knife.

5, workpiece clamping

If the clamping of the workpiece is not solid or the clamping is not firm, it will cause the knife to break.

6, cutting fluid

It is obvious in the processing of hard metal.

7. Surrounding environment

For example, the surrounding vibration source will affect the machining state and lead to the broken knife, and the abnormal working state of the machine tool will also lead to the abnormal working state of the machine tool due to the unstable voltage or beyond the working range of the engraving machine.
