How to deburr cross holes

Burr is ubiquitous in metal processing. No matter how advanced precision equipment you use, it will be born with the product. Burr is mainly a kind of excess iron filings generated at the machined edge due to plastic deformation of the material.

Burr not only affects the dimensional accuracy, shape accuracy and measurement accuracy of the workpiece, but also affects the workpiece assembly. After the burr falls off, the moving parts will be stuck and the lubrication system will be blocked.

There are many kinds of deburring methods, and there are many kinds of deburring tools and machines.

Today, we want to introduce a tool mainly used to remove cross hole burr: HSD cross hole (through hole) deburring chamfering tool, which comes from Germany and is used by many foreign companies.

HSD cross hole (through hole) can process all transverse holes penetrating the main hole through one axial processing of the main hole. Unlike other traditional tools, HSD cross hole (through hole) deburring chamfering cutter does not need to process each transverse hole separately, saving a lot of time and time. Of course, you can also choose to process and deburr from the transverse hole of through perforation.

Typical application quick Wizard

Firstly, it is clear what is the main hole and what is the through hole. The diameters of the main hole and the through hole can be different.

The main hole is the first drilled hole, the through hole is the later drilled hole, and the burr will be on one side of the main hole.

Rule: use HSD deburring tool, preferably in the main hole.

Case A: the main hole is drilled first, and then drilled through the hole, and the burr is on one side of the main hole. HSD deburring tool is cut in the main hole, which is the best choice. Regardless of the diameter ratio of the main hole to the through hole. 去毛刺|倒角|浮动铰刀柄|滚压刀

Case B1: drill the main hole first, and then drill the through hole. The burr is on one side of the main hole, and the HSD deburring tool cuts from the through hole. Usually, it is impossible to completely remove the burr.

Case B2: first drill the main hole, then drill the through hole, the burr is on one side of the main hole, and the HSD deburring tool cuts from the through hole.

It is feasible in two cases:

1.For brittle materials (such as cast iron);
2. The diameter of the main hole is much larger than that of the through hole;
3. It is also possible that the outlet of drilling through is an unprocessed surface or an unprocessed arc surface (such as cast iron)
Generally, it is not recommended to use it when the drill through outlet is completely flat
