Abstract

The utility model discloses a kind of CBN cutters with dovetail groove, including metallic matrix and CBN cutter heads, center mounting hole and dove-tail form groove are provided with its described metallic matrix, the CBN cutter heads have the dovetail shaped mutually identical with metallic matrix dovetail groove raised, in the dove-tail form groove of the raised embedded metallic matrix of the dovetail shaped of CBN cutter heads, linked together with metallic matrix.It is provided with to break at the CBN cutter heads nose-cut-ting edge and cuts groove, disconnected groove of cutting is V-shaped, more than drift angle at cutting edge, angle is 78 degree to angle.The utility model has saved material by using dovetail groove attachment structure, reduces use cost, and cutter head can be made to be combined with matrix well, and CBN cutter heads are difficult to loosen;CBN cutter heads front end is provided with to break cuts groove, it is possible to increase cutting-tool's used life, improves processing efficiency.

Description

A kind of CBN cutters with dovetail groove
Technical field
The utility model belongs to superhard cutter technical field, and in particular to a kind of CBN cutters with dovetail groove.
Background technology
Existing CBN blade is overall one piece, and blade shapes are generally square, triangle, rhombus etc., therefore processing High cost, certain customers are difficult to receive;In Precision Machining field, integral replacing, blade material utilization rate are needed after blade abrasion It is low;In the roughing stage, the increase of cutting depth is usually associated with, chip is not easily broken, influences workpiece surface crudy, The safety also to operator has an impact simultaneously, and chip also needs to manually process, waste of manpower, influences operating efficiency.
Utility model content
Technical problem to be solved in the utility model is directed to above drawback and provides a kind of CBN cutters with dovetail groove. What the utility model was realized particular by following technical scheme:
A kind of CBN cutters with dovetail groove, including metallic matrix and CBN cutter heads, in being provided with its described metallic matrix Heart mounting hole and dove-tail form groove, the CBN cutter heads have the dovetail shaped mutually identical with metallic matrix dovetail groove raised, CBN In the dove-tail form groove of the raised embedded metallic matrix of the dovetail shaped of cutter head, linked together with metallic matrix.
Further, it is provided with to break at the CBN cutter heads nose-cut-ting edge and cuts groove, disconnected groove of cutting is V-shaped, and angle is more than cutting Drift angle at sword, angle [alpha] is 78 degree.
Further, disconnected groove cross section of cutting is V-shaped, and angle beta is 130 degree.
Further, mounting hole is shaped as triangle.
The utility model can reach following beneficial effect:The utility model is saved by using dovetail groove attachment structure Material, reduces use cost, and cutter head can be made to be combined with matrix well, and CBN cutter heads are difficult to loosen;CBN cutter heads front end sets It is equipped with to break and cuts groove, it is possible to increase cutting-tool's used life, improves processing efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutter head position profile of Fig. 1;
In figure:1st, break and cut groove, 2, CBN cutter heads, 3, triangle pilot hole, 4, metallic matrix.
Specific embodiment
As shown in Figure 1, 2, a kind of CBN cutters with dovetail groove, including metallic matrix 4 and CBN cutter heads 2, its described metal It is provided with center mounting hole 3 and dove-tail form groove on matrix, the CBN cutter heads have mutually identical with metallic matrix dovetail groove Dovetail shaped is raised, in the dove-tail form groove of the raised embedded metallic matrix of dovetail shaped of CBN cutter heads, one is connected to metallic matrix Rise.It is provided with to break at the CBN cutter heads nose-cut-ting edge and cuts groove, disconnected groove of cutting is V-shaped, and angle is more than drift angle, angle [alpha] at cutting edge It it is 78 degree, disconnected groove cross section of cutting is V-shaped, and angle beta is 130 degree.Mounting hole is shaped as triangle.
