Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a finishing blade with grinding effect. Background Technology

[0002] In actual turning and milling operations, insufficient rigidity of the machine tool itself and deviations in the precision of tool manufacturing can cause vibrations in the tool during machining, affecting the accuracy of the workpiece, especially its surface finish. In traditional finishing inserts, the junction between the curved structure and the tool body is often transitioned through two straight-edge sections. These straight-edge sections, tool body, and curved structure are prone to joint marks, leading to wear in this area during workpiece machining. This results in the workpiece not achieving the required surface finish. The efficiency, precision, and service life of the finishing insert directly affect the workpiece's surface finish and the insert's lifespan. Furthermore, traditional machining processes often require grinding to achieve the desired surface finish (resulting in a longer machining cycle time), extending the production cycle.

[0003] Existing technologies have also made some improvements to straight-edge structures. For example, utility model application number 201320654743.1 discloses a finishing blade, including a blade body and an arc structure, which are integrally formed. The arc structure includes at least two arc segments; specifically, arc I, arc II, and arc III, a total of three arc segments, which smoothly connect. This utility model can, to a certain extent, avoid the formation of seams at the abrupt junction of the arc structure and the straight-edge structure, thus improving the surface finish and finishing efficiency of the workpiece.

[0004] However, the service life of existing finishing blades still needs to be improved, and the current structure cannot achieve the effect of "replacing grinding with turning". Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a finishing insert with grinding effect. It employs high-hardness, high-wear-resistance CBN (cubic boron nitride) as the main material of the finishing insert, enabling it to maintain stable cutting performance during prolonged, high-intensity cutting processes, reducing the need for frequent tool replacements due to wear. Through adjustments and improvements to the finishing insert structure, the invention achieves the technical effect of "turning instead of grinding," achieving or approaching the grinding effect in a single turning operation, thereby simplifying the production process and significantly improving production efficiency.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a finishing blade with grinding effect, comprising a blade body; the blade body includes a first surface and a second surface arranged in parallel, and a side peripheral surface disposed between the first surface and the second surface; the first surface and the side peripheral surface are connected by a plurality of first side cut surfaces, and the second surface and the side peripheral surface are connected by a plurality of second side cut surfaces; each first side cut surface and the corresponding second side cut surface are arranged symmetrically about the central axis of the side peripheral surface; the included angle between the first side cut surface and the first surface, and the included angle between the second side cut surface and the second surface are equal, and the degree of the included angle is between 10 and 30 degrees.

[0007] Furthermore, the lateral surface is formed by connecting at least three identical side surfaces end to end; the intersection of each side surface with the corresponding first side section and second side section is a side edge, and the intersection of the first surface with each first side section and the second surface with each second side section is a face edge; the side edges and the corresponding face edges are parallel to each other.

[0008] Furthermore, the connection between adjacent side edges includes a straight segment and an arc segment; one end of the straight segment is connected to the side edge, and the other end is connected to the arc segment; one end of the arc segment is connected to the straight segment, and the other end is connected to another side edge; adjacent face edges are connected by straight segments.

[0009] Furthermore, the side edge straight segment and the face edge straight segment are arranged parallel to each other, and the length of the side edge straight segment is greater than that of the face edge straight segment.

[0010] Furthermore, the angle between the straight segment of the side edge and the side edge it is connected to is α1, and the range of α1 is 120 to 160 degrees; the angles formed between the straight segment of the face edge and the face edge it is connected to are α2 and β, respectively, where α2 = α1 and the range of β is 60 to 90 degrees.

[0011] Furthermore, the thickness of both the first and second side sections is 0.15–0.3 mm.

[0012] Furthermore, the blade body is made of cubic boron nitride.

[0013] The beneficial effects of this utility model are: compared with the prior art, the finishing insert with grinding effect provided by this utility model is an improvement over traditional cutting inserts.

[0014] Structurally, the sharpness of the cutting edge is improved by designing the inclination angles of the first and second side facets; the cutting effect, finishing effect, and surface smoothness of the workpiece are improved by designing the straight and curved segments of the side edges between each side edge, as well as the straight segments of the face edges between each face edge; and the cutting effect and cutting efficiency are further improved by controlling the included angles between the straight segments of the side edges and between the straight segments of the face edges and the face edges.

[0015] In terms of materials, CBN is used as the main material of the cutting tool. CBN finishing cutting tools, with their excellent cutting performance and surface finish retention, can achieve or approach the grinding effect in a single turning process, thereby simplifying the production process and significantly improving production efficiency.

[0016] In summary, the finishing insert provided by this utility model significantly improves tool life by "replacing grinding with turning," bringing revolutionary changes to the machining industry from both efficiency and cost perspectives, and promoting the improvement of enterprise production efficiency and the reduction of production costs.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example

[0024] like Figures 1 to 4As shown, a finishing blade with a grinding effect includes a blade body; the blade body includes a first surface 1 and a second surface 2 arranged in parallel, and a side peripheral surface 3 disposed between the first surface 1 and the second surface 2; the first surface 1 and the side peripheral surface 3 are connected by a plurality of first side cut surfaces 4, and the second surface 2 and the side peripheral surface 3 are connected by a plurality of second side cut surfaces 5; each first side cut surface 4 and the corresponding second side cut surface 5 are arranged symmetrically about the central axis of the side peripheral surface 3; the included angle between the first side cut surface 4 and the first surface 1, and the included angle between the second side cut surface 5 and the second surface 2 are equal, and the degree of the included angle is between 10 and 30 degrees.

[0025] In this embodiment, the lateral surface 3 is formed by three identical side surfaces 6 connected end to end; the lateral surface 3, the first surface 1, and the second surface 2 together form a triangular pyramid. Each side surface 6 is connected to a corresponding first side section 4 and a second side section 5, and the connection point is a side edge 8. The connection points between the first surface 1 and each first side section 4, and between the second surface 2 and each second side section 5, are face edges 7. In this embodiment, there are three side edges 8 and three face edges 7; the side edges 8 and the corresponding face edges 7 are parallel to each other. The first side section 4 and the second side section 5 form cutting edges to cut the workpiece. The first side section 4 and the second side section 5 form an angle with the first surface 1 and the second surface 2. In this embodiment, the angle is set to 15 degrees, and the angle design can enhance the cutting effect.

[0026] In this embodiment, the connection between two adjacent side edges 8 includes a straight side edge segment 11 and a curved side edge segment 9. One end of the straight side edge segment 11 is connected to the side edge 8, and the other end is connected to the curved side edge segment 9. One end of the curved side edge segment 9 is connected to the straight side edge segment 11, and the other end is connected to another side edge 8. Adjacent face edges 7 are connected by a straight face edge segment 10. The straight side edge segment 11 and the straight face edge segment 10 are parallel, and the length of the straight side edge segment 11 is greater than that of the straight face edge segment 10. The curved side edge segment 9 is an arc. Using the straight side edge segment 11 as the transition segment between two side edges 8 and the straight face edge segment 10 as the transition segment between two face edges 7 greatly improves the sharpness of the finishing blade and increases the cutting effect. In this embodiment, the number of straight side edge segments 11 is three, further improving the cutting effect and service life of the blade. Using an arc shape as the transition section between the two side edges 8 makes the transition smoother, avoids the formation of seams, and makes the finishing blade provided in this embodiment less wear and better finishing effect when processing workpieces; it also extends the service life of the blade.

[0027] The angle between the side edge straight segment 11 and its connected side edge 8 is α1, and the range of α1 is 120-160 degrees; in this embodiment, α1 is preferably 150 degrees. The angles formed between the face edge straight segment 10 and its connected face edge 7 are α2 and β, respectively, where α2 = α1 = 150 degrees, and the range of β is 60-90 degrees; in this embodiment, β is preferably 80 degrees. The side edge straight segment 11 and its connected side edge 8, as well as the face edge straight segment 10 and its connected face edge 7, form the same angle, which improves the sharpness of the "blade".

[0028] The thickness of both the first side section 4 and the second side section 5 is 0.15–0.3 mm. In this embodiment, the thickness of the first side section 4 and the second side section 5 is preferably 0.2 mm.

[0029] In this embodiment, the blade body is made of cubic boron nitride (CBN). CBN is known for its high hardness and wear resistance, allowing finishing blades to maintain stable cutting performance even during prolonged, high-intensity cutting processes, reducing the need for frequent tool replacements due to wear. This extended lifespan not only reduces downtime for tool changes but also lowers tool consumption costs, bringing significant economic benefits to the company. Simultaneously, a longer tool life also means less waste, contributing to green production and aligning with sustainable development principles. Compared to ordinary tools, CBN finishing blades can have approximately 30% longer lifespans, an advantage that is crucial for reducing production costs.

[0030] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
