Abstract
The utility model relates to a machining cutter, in particular to a round nose cutter. The cutter comprises a cutter handle for clamping and a cutting head arranged at one end of the cutter handle. The front end of the cutting head is a cutting end face, three end face cutting edges and three straight cutting edges axially arranged along the cutting head are arranged on the cutting end face, each end face cutting edge is correspondingly connected with a straight cutting edge, and the face cutting edges are connected with the straight cutting edges through transition circular arcs. After the structure is adopted, the face cutting edges are connected with the straight cutting edges through the transition circular arcs, and thus the round nose cutter is not prone to blocking when machining is carried out, and machining effects are good.
Description
Technical field
The utility model relates to a kind of machining tool, particularly a kind of round nose cutter.
Background technology
The round nose cutter, the general expression embedded structure, more allowing blade replacement all can make tool dimension A Sheng slight change at every turn, does not have static cutting edge, and the wearing and tearing of blade are also less, and the cutter spacing also can strengthen.But some processing work not only needs the round nose cutter can carry out end face processing, and also needing can straight line processing.
Summary of the invention
The utility model technical issues that need to address provide the good round nose cutter of a kind of processing effect.
For solving above-mentioned technical problem, three sword round nose cuttves of the present utility model comprise the handle of a knife and the cutter head that is arranged on handle of a knife one end for clamping, described cutter head front end is the cutting end face, be provided with three face cutting edges on the described cutting end face, and along axial three linear cutting edges that arrange of cutter head, each face cutting edge is corresponding to connect a linear cutting edge, is connected by transition arc between described face cutting edge and the linear cutting edge.
The radius of described transition arc is 0.3mm.
Described cutter head axial length is 15mm, and described handle of a knife axial length is 35mm.
The diameter of described handle of a knife is 10mm.
After adopting said structure, be connected by transition arc between the utility model face cutting edge and the linear cutting edge, so that round nose cutter of the present utility model adds and is difficult for man-hour stuckly, processing effect is better.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of A section among the utility model Fig. 1.
Among the figure: 1 is handle of a knife, and 2 is cutter head, and 3 is face cutting edge, and 4 is linear cutting edge, and 5 is transition arc
The specific embodiment
Three sword round nose cuttves as depicted in figs. 1 and 2 comprise handle of a knife 1 and the cutter head 2 that is arranged on handle of a knife 1 one ends for clamping.Described cutter head 2 axial lengths are 15mm, and described handle of a knife 1 axial length is 35mm, and the diameter of described handle of a knife is 10mm.
Described cutter head 2 front ends are the cutting end face, be provided with three face cutting edges 3 on the described cutting end face, and along cutter head 2 axial three linear cutting edges 4 that arrange, linear cutting edge of the corresponding connection of each face cutting edge, be connected by transition arc 5 between described face cutting edge 3 and the linear cutting edge 4, the radius of described transition arc is 0.3mm.
