Description

Technical Field

[0001] The utility model belongs to the technical field of machining tools, in particular to a round nose milling cutter for cutting profiles. Background Art

[0002] End mills are the most commonly used milling cutters on CNC machine tools. There are cutting blades on the cylindrical surface and end face of the end mill. They can cut simultaneously or separately. They are mainly used for plane milling, groove milling, step surface milling and profile milling. Round nose milling cutters are a type of end mill. They are a type of tool with the length of the arc part greater than 1 / 4 circle. Round nose milling cutters are widely used in the processing of various materials, including metals, plastics and composite materials.

[0003] The round nose milling cutter is usually fixed on the tool holder of the CNC machine tool when in use.
