Description

Technical Field

[0001] The utility model relates to the field of a coarse and fine integrated milling cutter, in particular to a coarse and fine integrated milling cutter with a replaceable cutter head. Background Art

[0002] Roughing and finishing milling cutters are primarily used on milling machines to machine flat surfaces, steps, grooves, formed surfaces, and cut off workpieces. A milling cutter is a rotating tool with one or more teeth used for milling. Each tooth sequentially and intermittently removes the workpiece's excess material. Roughing and finishing milling cutters combine roughing and finishing heads, enabling roughing and finishing without the need for head replacement.

[0003] In the prior art, a coarse-fine milling cutter is prone to surface wear under long-term high-intensity work. In order to reduce costs, a coarse-fine milling cutter with a replaceable cutter head is usually used, which eliminates the need to replace the milling cutter, thereby reducing production costs.

[0004] However, existing coarse and fine milling cutters with replaceable cutter heads can usually only be used to clamp coarse and fine cutter heads of a single specification. When coarse and fine cutter heads of different specifications need to be replaced, the milling cutter handle also needs to be replaced. The adaptability is low, the disassembly and assembly takes a long time, the production line efficiency is reduced, the workload of the staff is heavy, and it is inconvenient for the staff to actually use it.
