Description

Fully ground cermet boring inserts

technical field

The utility model relates to the technical field of precision machining technology and precision machining equipment, in particular to a cutting tool for precision machining, in particular to a fully ground cermet boring blade.

Background technique

Boring insert is a kind of turning tool, which is often used in the processing of round bar workpieces; it is a tool used for finishing rough-machined workpiece blanks.

At present, boring inserts are generally provided with one cutting edge, and corresponding inserts need to be replaced when corresponding to different processing needs. The configuration of multiple inserts seriously wastes production resources, and at the same time, the tool change process affects processing efficiency.

Furthermore, it is particularly necessary to provide multi-position boring inserts that can adapt to various processing occasions, reduce waste of resources, reduce tool changing procedures and improve processing efficiency.

Therefore, it is necessary to provide a fully ground cermet boring insert to solve the above problems.

Utility model content

The purpose of the utility model is to provide a fully ground cermet boring blade.

The utility model realizes above-mentioned purpose through following technical scheme:

A fully ground cermet boring blade includes a boring body formed by grinding. The boring body is in a polygonal shape and includes at least three boring blades. The three boring blades correspond to different angles: It includes the upper edge surface of the boring tool arranged obliquely upward, a set of side surfaces corresponds to the combination of one of the upper edge surfaces of the boring tool to form the boring tool body of the cutting edge of the boring tool, and a plurality of boring tool bodies are correspondingly combined to form multiple One-piece boring tool structure.

Further, the boring tool body includes an upper surface, and a boring tool clamping groove is provided in the middle of the upper surface.

Further, the upper edge surface and the upper edge surface of the boring tool are connected through an oblique connecting surface.

Further, the oblique connection surface forms a smooth chip removal part corresponding to the boring tool body, thereby forming a smooth oblique chip removal type boring tool structure.

Further, the body of the boring tool is narrow at the bottom and wide at the top.

Further, the edges of the included angle formed by the combination of the side surfaces of the boring tool body are arranged in an arc shape.

Further, the boring tool clamping groove includes a connecting groove and a positioning groove corresponding to the connecting groove, and an arc-shaped connecting pulling arc module is arranged between the connecting groove and the positioning groove.

Compared with the prior art, the utility model can meet the processing needs of different processing occasions through the setting of the multi-position integrated boring tool structure, reduce the waste of production resources caused by the setting of multiple boring tools, and reduce the tool change process. The impact on production efficiency in the future is convenient for enterprises to implement efficient production and optimize production costs.

detailed description

Example:

Referring to Figures 1-3, this embodiment shows a fully ground cermet boring blade, including a boring tool body 1 formed by grinding. The boring tool body 1 is in a polygonal shape and includes at least three boring tool blades 2, The three boring cutter blades 2 correspond to different angles: including the boring cutter upper blade surface 21 arranged obliquely upward, and a group of side surfaces 11 corresponding to one of the boring cutter upper blade surfaces 21 combined to form the boring cutter blade 2 of the boring tool body 100, a plurality of boring tool bodies 100 are correspondingly combined to form a multi-position integrated boring tool structure.

The boring tool body 1 includes an upper surface 3 , and a boring tool clamping groove 4 is provided in the middle of the upper surface 3 .

The upper edge surface 3 and the upper edge surface 21 of the boring tool are connected by an oblique connecting surface 5 .

The oblique connection surface 5 forms a smooth chip removal part corresponding to the boring tool body 1, and further forms a smooth oblique chip removal type boring tool structure.

The boring tool body 1 is narrow at the bottom and wide at the top.

The edges of the angle 200 formed by the combination of the side surfaces 11 of the boring tool body 1 are arranged in an arc shape.

The boring tool clamping groove 4 includes a connecting groove 41 and a positioning groove 42 corresponding to the connecting groove 41 , and an arc-shaped connecting pulling arc module 43 is arranged between the connecting groove 41 and the positioning groove 42 .

Compared with the prior art, the utility model can meet the processing needs of different processing occasions through the setting of the multi-position integrated boring tool structure, reduce the waste of production resources caused by the setting of multiple boring tools, and reduce the tool change process. The impact on production efficiency in the future is convenient for enterprises to implement efficient production and optimize production costs.

What have been described above are only some embodiments of the present utility model. For those skilled in the art, without departing from the inventive concept of the present utility model, some modifications and improvements can be made, and these all belong to the protection scope of the present utility model.
