Description

A water-cooled four-edge countersunk milling cutter

Technical Field

The utility model belongs to the field of milling cutters, in particular to a water-cooled four-edge countersunk milling cutter.

Background Art

At present, milling cutter is one of the commonly used tools for machining parts in factories, and countersunk milling cutter generally has a new cutter body extending from the top of the blade, which is used for drilling or countersinking of workpieces. However, in the prior art, there are countersunk milling cutters with a flat head on the top of the cutter body and lack of cooling means, which can easily cause the milling cutter to be gradually damaged by large cutting force and high temperature, affecting the factory's production and processing. Therefore, producing a milling cutter that can reduce the cutting force and temperature of the cutter body is also one of the improvement directions that manufacturers currently pay attention to.

A Chinese patent with publication number CN218555701U discloses a milling cutter for high-gloss surfaces of aluminum alloys. The milling cutter of this application can achieve high-gloss or mirror effects on workpieces by processing workpieces, but the application still has some structural problems. Specifically, in terms of composition structure, there is a lack of a spherical or hemispherical tool body, and there is also a lack of a structure that can cool down. It is foreseeable that this may cause the tool to be subjected to greater cutting forces, and the heat generated during processing cannot be effectively removed. In the long run, it is easy to cause damage to the tool, affecting the factory's production and processing.
