Description

3D milling cutter

Technical Field

The utility model relates to a milling cutter technical field, concretely relates to 3D milling cutter.

Background

The application of wood board processing and carving is more and more extensive, and the processing requirements of consumers on products are higher and higher. In the milling cutter in the prior art, only the side cutting edge can be used for machining, and on the contrary, only the end cutting edge of the drill can be used for cutting, so that the drill and the milling cutter need to be frequently replaced in the actual machining process, and therefore, the machining speed is affected.

SUMMERY OF THE UTILITY MODEL

For solving not enough among the prior art, the utility model provides a 3D milling cutter has solved among the prior art milling cutter, drill bit and can't carry out the technical problem that lateral part, tip cut simultaneously.

In order to realize the above object, the utility model adopts the following technical scheme:

the utility model provides a 3D milling cutter, includes the handle of a knife and sets up in the cutting section of handle of a knife tip: the cutting section comprises a front end cutting edge arranged at the end part, a side cutting edge arranged at the side part and a chip groove, a rear end cutter face extending to the chip groove is arranged behind the front end cutting edge, the height of the rear end cutter face is sequentially reduced from the front end cutting edge to the chip groove, and the side cutting edge and the chip groove are synchronously and spirally arranged.

As a preferred scheme of the utility model, aforementioned 3D milling cutter: the number of the chip grooves is two, and the two chip grooves are symmetrically and spirally arranged by taking the axis of the cutter handle as a center.

As a preferred scheme of the utility model, aforementioned 3D milling cutter: the end relief surface is planar.

As a preferred scheme of the utility model, aforementioned 3D milling cutter: a Z-shaped boundary is further arranged between the two end rear cutter faces, and the center of the Z-shaped boundary is overlapped with the center of the cutter handle.

As a preferred scheme of the utility model, aforementioned 3D milling cutter: the helix angle of the flutes is in the range of-degrees.

As a preferred scheme of the utility model, aforementioned 3D milling cutter: the surface roughness of the 3D milling cutter is not higher than 0.8.

The utility model discloses the beneficial effect who reaches: compared with the prior art, the utility model has the advantages that the three-dimensional (3D) processing can be really realized by longitudinally punching, transversely cutting and obliquely moving, and the design of a larger scientific chip groove is adopted, so that the chip can be more quickly arranged and cut, and the working efficiency is higher; no burr is left at the position where the workpiece passes through the cutter, and the cutter edge is smooth and flat; it is suitable for advertisement carving machine, woodwork carving machine, etc. Because the end part and the side part have the cutting function at the same time, the probability of cutter breakage in the actual machining process is greatly reduced.

The utility model discloses a roughness is lower, adopts mirror surface sword to grind technology, and large capacity chip groove, the edge of a knife is sharp, wear-resisting, and the tangent plane is smooth fine and smooth, exempts from polishing, on-stick sword, smokeless, tasteless, silence.

fig. 2 is an end view of the present invention;

the meaning of the reference numerals: 1-end front blade; 2-end flank face; 3-chip removal groove; 4-a knife handle; 5-side cutting edge; 6-side flank face; a 7-Z type boundary.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 and 2: the broken line in fig. 2 indicates the arc on which the shank 4 is located, and the arrow in fig. 2 indicates the direction in which the tool rotates. The embodiment discloses a 3D milling cutter, include handle of a knife 4 and set up in the cutting section of 4 tip of handle of a knife: the cutting segment includes an end portion rake 1 provided at the end portion, a side cutting edge 5 provided at the side portion, and a chip groove 3, an end portion flank 2 extending to the chip groove 3 is provided behind the end portion rake 1, and the height of the end portion flank 2 decreases in order from the end portion rake 1 to the chip groove 3, where the height is a distance from the cutting end portion, and the end portion flank 2 is a plane surface in the present embodiment.

The side cutting edge 5 and the chip groove 3 are both arranged in a synchronous spiral manner, and the side cutting edge 5 is arranged in front of the chip groove 3 (in the direction of feed during operation).

The number of the chip grooves 3 is two, and the two chip grooves 3 are symmetrically and spirally arranged by taking the axis of the cutter handle 4 as a center.

A Z-shaped dividing line 7 is also provided between the two end flank surfaces 2, and the center of the Z-shaped dividing line 7 (solid black dot in fig. 2) coincides with the center of the shank 4.
