Diamond knives are rare in our lives, but they are indeed widely used in industrial processing today. Let's take a look at the problems of diamond cutting tools in processing.

We all know that in addition to the size requirements, there is a very important requirement for diamond tools, which is that the cutting edge has no chipping. What we call no chipping means that no chipping can be seen under the condition of 500 times magnification. We can detect the size problem directly with professional tools. Now let’s talk about collapse:

There are many types of edge chipping, we can take a look at them.

1, Xiaobangqian

That is, there is a chipping less than 3um on the cutting edge of the tool. This kind of tool does not need to be repaired, and it is directly collected after one. It is so-called just one cut and it is OK.

2, collapse

This kind of chipping is a bit big, usually between 3um and 10um. We repair this kind of tool according to the actual situation. Some tools need to be polished a little bit, and some can be repaired directly. This should be processed according to one's own experience.

3, the big collapse

This kind of tool is very troublesome after being returned. It has to be repaired, and some parts have to be laser cut, and then reopened. Sometimes, the margin is insufficient and it is directly NG processed.

4, scratches

Scratches are not common in our processing. If this type of tool fails to work after being repaired again, we will directly NG it.

5, sawtooth

This is rarely seen as a result of the internal stress released in the diamond after a long time. We just need to repair a knife between us, because the breakage of this type of knife is generally not very large.

This is the problem we often have at work. I hope it will help you.
