Description
Technical Field
The utility model belongs to the field of numerical control cutters, and particularly relates to a three-blade chip breaking and cutting cutter.
Background
The existing wood cutting knife has the problems of easy knife body breakage, unsmooth chip removal, easy edge explosion of wood and the like.
SUMMERY OF THE UTILITY MODEL
The utility model provides a three-blade chip breaking and cutting knife for solving the technical problems.
The solution adopted by the utility model for realizing the technical effect is as follows:
the three-blade chip breaking and cutting knife comprises a rotating shaft, a connector and a blade main body; the connector is arranged at one end of the rotating shaft; the blade body comprises three blades; one end of each of the three blades is arranged at one end of the connector; the inner sides of the three cutting edges are mutually and circularly spliced together, and the outer sides of the three cutting edges are mutually and circularly arranged at equal intervals; a chip groove, a knife back and a blade are arranged on the outer side of the cutting edge; the knife back is arranged between the chip groove and the blade; open troughs are arranged on the blade and the blade back, and the open troughs on the different blades are staggered with each other.
