Description

Technical Field

[0001] This utility model belongs to the technical field of diamond cutting tools, specifically a high-sharpness, high-cutting-edge diamond cutting tool. Background Technology

[0002] In fields such as stone processing, glass cutting, and precision machining of hard and brittle materials, diamond cutting tips, due to the high hardness of diamond, have become core components for achieving efficient cutting operations. As modern manufacturing demands ever-increasing processing precision, cutting efficiency, and workpiece edge quality, the market has set higher standards for the performance of diamond cutting tips, especially in maintaining sharpness stability during long-term cutting and ensuring the smoothness and chip-free edges of the cut workpiece. This requires superior technical solutions. Against this backdrop, a diamond cutting tip with high sharpness and high edge quality has emerged.

[0003] The cutting section of existing diamond cutter heads mostly adopts a single slope or equal area and equal grit diamond design, which easily leads to contradictions such as insufficient finishing coverage or low material breaking efficiency during cutting, making it difficult to achieve both high-efficiency cutting and high-quality cutting edges.

[0004] Therefore, a high-sharpness, high-cutting-edge diamond cutting tip is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a high-sharpness, high-cutting-edge diamond cutter head, which has the advantages of comprehensively trimming the cutting surface, achieving simultaneous high-sharpness material breaking and high-flatness cutting edge, supplementing the high-efficiency operation requirements of the cutting part, and improving the overall stability and safety of the cutter head.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-sharpness, high-cutting-edge diamond cutting tip, comprising a cutting tip body, the cutting tip body comprising a cutting part and a base part, the cutting part comprising two interconnected slopes, slope one and slope two, the area of ​​slope one being larger than the area of ​​slope two, and the diamond particles embedded on slope one having a smaller particle size than the diamond particles on slope two.

[0007] Preferably, both the first and second slope surfaces are covered with a metal-ceramic wear-resistant coating.

[0008] Preferably, slope one and slope two are connected by an arc-shaped transition surface.

[0009] Preferably, chip removal grooves are provided at both ends of the base portion, and anti-splash protrusions are fixedly connected to one side of the openings of the two chip removal grooves.

[0010] Preferably, the cross-sections of both chip removal grooves are trapezoidal, and the two chip removal grooves are mirror images of each other.

[0011] Preferably, the width of the anti-splash ridge is greater than the depth of the chip removal groove.

[0012] Preferably, the base portion, the splash-proof protrusion, and the cutting portion are integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting up a cutting section, this utility model allows the coarse-grained diamonds on slope one to concentrate force and quickly break the surface layer of the material when the area of ​​slope one is larger than that of slope two and the diamond particle size on slope one is smaller than that on slope two. At the same time, the large area of ​​fine-grained diamonds on slope one fully covers the coarse cutting area and comprehensively trims the cutting surface, achieving a simultaneous balance between high-sharpness material breaking and high-flatness cutting edge.

[0015] 2. This utility model provides trapezoidal chip removal grooves at both ends of the base and anti-splash protrusions with a width greater than the groove depth on one side of the groove opening. This allows the gradually expanding structure of the trapezoidal grooves to accelerate chip removal and avoid clogging. At the same time, the anti-splash protrusions can prevent disorderly chip splashing to protect the workpiece surface. This not only meets the high-efficiency operation requirements of the cutting part but also improves the overall stability and safety of the tool head. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, this utility model provides a high-sharpness, high-cutting-edge diamond cutting tip, including a cutting tip body 1.

[0025] The cutter head body 1 includes a cutting part 12 and a base part 11;

[0026] The cutting section 12 consists of two interconnected slopes, one 122 and the other 121. The area of ​​slope one 122 is larger than that of slope two 121. The diamond particles embedded on slope one 122 are smaller than those on slope two 121. This allows slope two 121 to concentrate force and quickly break the material surface layer. At the same time, slope one 122 fully covers the rough cutting area for fine finishing, solving the problem of "incomplete fine finishing or low material breaking efficiency" of existing cutters. This achieves a balance between high-sharpness material breaking and high-flatness cutting edge.

[0027] Specifically, both slope surface 122 and slope surface 21 are covered with a metal-ceramic wear-resistant coating. The metal-ceramic wear-resistant coating can enhance the wear resistance of slope surface 122 and slope surface 2121, reduce the direct friction loss between diamond particles and materials during cutting, and extend the finishing life of fine-grained diamonds on slope surface 122 and the breaking life of coarse-grained diamonds on slope surface 2121.

[0028] like Figures 1 to 4 As shown, slope 122 and slope 21 are connected by an arc-shaped transition surface. The arc-shaped transition surface can guide the cutting debris generated by cutting to slide smoothly from slope 21 to slope 122, avoiding the accumulation of debris at the junction of the two slopes, preventing the accumulated debris from abrading the fine-grained diamond on slope 122, and ensuring stable finishing effect.

[0029] Furthermore, chip removal grooves 112 are provided at both ends of the base part 11, and anti-splash protrusions 111 are fixedly connected to one side of the opening of each chip removal groove 112. The chip removal grooves 112 at both ends of the base part 11 can promptly receive and discharge the chips that slide off from the cutting part 12. The anti-splash protrusions 111 can prevent chips from splashing outward, thus avoiding chips from scratching the surface of the finished workpiece or interfering with the operator, and improving cutting safety.

[0030] like Figures 1 to 4 As shown, the cross-sections of the two chip removal grooves 112 are both trapezoidal, and the two chip removal grooves 112 are mirror-distributed, which can effectively avoid uneven force on the cutting head caused by chip blockage on one side and ensure the stability of the cutting process.

[0031] It is worth noting that the width of the anti-splash ridge 111 is greater than the depth of the chip discharge groove 112. The width of the anti-splash ridge 111 is greater than the depth of the chip discharge groove 112, which can form a wider lateral protective barrier, completely covering the opening area of ​​the chip discharge groove 112, effectively blocking high-speed flying debris, while enhancing the impact resistance of the anti-splash ridge 111 itself, and preventing it from deforming due to debris impact.

[0032] like Figures 1 to 4 As shown, the base part 11, the anti-splash protrusion 111 and the cutting part 12 are integrally formed. The integrally formed structure can eliminate the connection gap between the base part 11, the anti-splash protrusion 111 and the cutting part 12, avoid the accumulation of debris or stress concentration in the gap during cutting, improve the overall structural rigidity of the tool head, and prevent the components from loosening or breaking during high-speed cutting.

[0033] Working principle and process: When the cutter head is working, the second slope 121 of the cutting part 12 first contacts the material to be cut, and the surface layer of the material is quickly broken off under the action of high-speed rotation. Then the first slope 122 of the cutting part 12 follows up to perform a comprehensive finishing of the rough cut surface. The chips generated by cutting slide down along the arc transition surface between the first slope 122 and the second slope 121 and enter the trapezoidal chip removal groove 112 of the base part 11. Then they are discharged along the chip removal groove 112. At the same time, the anti-splash ridge 111 blocks the splashing of chips. The integral molding structure of the base part 11, the anti-splash ridge 111 and the cutting part 12 ensures the overall stability of the force. The metal ceramic coating on the surface of the first slope 122 and the second slope 121 reduces wear, and finally achieves efficient, high-precision and stable cutting operation.
