Abstract
The utility model relates to a four-edge coarse milling cutter. The four-edge coarse milling cutter comprises a bar and a bit, wherein four end face cutting edges and four corresponding wave edges are arranged at the end of the bit; the wave edges are helical; helical chip grooves are formed between the adjacent wave edges; the helical angles of the chip grooves are 22 degrees; the wave edges are formed by arranging a plurality of concave-convex edges in sequence; bevels of the concave-convex edges and the horizontal plane form angles of 45 degrees; an aluminium-titanium nitride coating is arranged on the surface of the bit; 45-degree chamfers are arranged at the end of the bar. By adopting the structure, the four-edge coarse milling cutter improves the chip removal efficiency in a machining process, thus ensuring the machining quality of a workpiece and simultaneously prolonging the service life of the milling cutter.
Description
Technical field
The utility model relates to a kind of four sword roughing milling cutters, particularly a kind of four sword roughing milling cutters.
Background technology
In machined, when workpiece is carried out to milling, in order to guarantee precision and the quality of workpiece milling, need first with roughing milling cutter, workpiece to be carried out to just milling, the bits that existing roughing milling cutter mills out when workpiece is carried out to just milling are not easy to discharge, blade is easily caused to damage, also easily surface of the work is produced and destroyed simultaneously, affect the crudy of workpiece and the service life of milling cutter.
Summary of the invention
The purpose of this utility model be to provide a kind of chip removal easily, long service life and the four sword roughing milling cutters high to the crudy of workpiece.
The technical scheme that realizes the utility model object is as follows:
A kind of four sword roughing milling cutters, comprise knife bar and cutter head, described cutter head end is provided with four face cutting edges and four corresponding wave edges, described wave edge in the shape of a spiral, between adjacent wave edge, be provided with helical form chip area, the helical angle of described chip area is 22 °, and described wave edge is arranged in order and is formed by the concavo-convex sword of multistage, the inclined-plane of described concavo-convex sword and horizontal plane angle at 45 °.
Described cutter head surface arranges TiAlN coating.
The end of described knife bar is provided with 45 ° of chamferings.
After adopting said structure, the utility model has improved the chip removal efficiency in process, has increased the service life of milling cutter when having guaranteed the quality of workpiece processing.
