Common reasons for cutting tool breaking of CNC Router wood working Machine
1.The problem of tool quality. No matter it is alloy, soldering, sintering or PCD diamond cutting tools, there are differences among high, medium and low grade. The quality of cutting tools is not good, so it is difficult to reduce cutting
2. The choice of Cutting tools type and model is incorrect.
The type is not selected correctly. For example, if we are engraving on granite, it is better to choose stone sintering tools. As usually, the very high quality brazing knives on the market are not suitable for engraving large-scale granite. Granite is hard, causing severe tool wear. After the tool wears, it is not far from the broken tool.
The longer the cutting tool or the longer the exposed part of the clamp, the worse the concentricity of the tool, the greater the elastic deformation, the greater the vibration, and the easier the tool breaks.
Generally speaking, for longer tools, we often need to increase the diameter of the tool and choose a thicker tool. As long as the cutter does not affect the engraving, the shorter the part that exposes the fixture, the better.
4. The Clamp of knife problems.
The clamps are not replaced for a long time, and the tools are not easy to clamp.
It is prone to problems such as stabbing, falling off, shrinking, etc., resulting in broken blades.
Attentive customers can find that the clamping nut of the clamp and the spindle, every one or two days of use, will accumulate some stone powder inside.
We should regularly clean up these stone powders, otherwise, it will affect the accuracy of the tool clamping and reduce the clamping effect of the fixture.
Friendly reminder: it is forbidden to use the extension rod clamping method and the hammer to hit the fastening nut. This is common sense. I hope you don't do this, as this will easily damage the clamps, the spindle, and even the screw, slider and other machine parts.
Machine problems, usually manifestations are poor rigidity, unstable movement, large vibration, too fast processing speed, too fast cutting speed, too high acceleration, poor tool cooling water spray effect, non-vertical spindle, unstable spindle speed, low spindle power 、 The main shaft rotates in reverse, the main shaft heats up, and there is a gap between the transmission parts.
Any of the above will affect the life of the tool and cause breakage. We can see that the spindle is one of the most important parts of the CNC Router engraving machine. It is very important to choose a spindle with high power and good quality.
6. There are problems with the engraved relief drawings.
1)There are obvious steps straight up and down. It's easy to break a knife if you stab it in.
2)The knife has full knife movement during engraving. What is a full knife? The full knife is like the first knife we carved in relief, because it is the first time to cut in, the bigger the knife, the bigger the carving. In some drawings, the edges of the drawings are not smooth contours, and have right-angled corners. In such a place, the probability of the stone engraving machine cutting tool is extremely great.
To avoid the broken knife above, it is not necessary to modify the drawing, and it can be handled separately during the programming process.
7.When processing, do not set the line spacing too large or the overlap ratio not set too small.
If the line spacing is too large, the force on the tool will be large when carving. It's like a porter unloading a load of goods. I have never seen any worker unload a load of goods at once.
The Same moving too many cargoes at a time will not improve efficiency.
The same is true for carving. Reasonably setting the line spacing can effectively reduce the number of broken knives.
