Description

Technical Field

[0001] The utility model belongs to the technical field of tool tools, in particular to an installation structure of a combined thread tool. Background Art

[0002] Thread cutters are generally used in CNC machining centers and CNC engraving machines. They can also be installed on ordinary milling machines to process some relatively hard and uncomplicated heat-treated materials. Tungsten steel milling cutters are widely used and use high-speed machining. Carbide tools are the leading products of CNC machining tools. In some countries, more than 90% of turning tools and more than 55% of milling cutters are made of carbide, and this trend is still increasing. Since the 1980s, the tool industry has continuously expanded the production of various integral and indexable carbide tools or blades, and its varieties have expanded to various cutting tool fields. Among them, indexable carbide tools have expanded from simple turning tools to various precision, complex, and forming tool fields. Carbide is also a common material for manufacturing general tools such as drills and face milling cutters.

[0003] The existing workpiece processing requires multiple processing with multiple tools, and the tool needs to be changed multiple times during processing. On the one hand, the processing efficiency is low, and on the other hand, the workpiece has poor integration. At the same time, most of the existing milling cutters cannot be assembled. The various components of the milling cutter are an integral structure. When the cutter head or shank of the milling cutter is damaged, the entire milling cutter often needs to be replaced, which greatly increases the cost of use. In order to solve the above problems, an installation structure of a combined thread tool is proposed. Utility Model Content
