Description
Technical Field
The utility model relates to a carbide tool technical field, more specifically say, it relates to an integrative milling cutter of rough finish machining of preceding ripples sword.
Background
Roughing milling cutters typically use wavy cutting edges or rows of cutting flutes, the cutting edges having large contact surfaces and thicker edges, roughing to remove a variety of materials, low cutting speed, large feed and cutter, low dimensional accuracy, low surface quality, and roughing for the purpose of quickly cutting down the remaining margin. Finish mills typically use sharp cutting edges and high tool strength, smooth cutting faces, high cutting accuracy, finish mills with less material removal, high cutting speed, ensuring final dimensional accuracy and surface quality.
However, the rough machining and the finish machining need to adopt two different cutters, and the cutter changing operation needs to occupy the machining time and affects the machining production efficiency, so the improvement is needed.
