[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-3The utility model provides an embodiment: a whole carbide aluminum engraving tool, comprising a handle 1, a transition arc 2 is fixedly connected to the left end of the handle 1, a tool body 3 is fixedly connected to the left end of the transition arc 2, the tool body 3 is made of ultrafine particle carbide, a tool tip 5 is fixedly connected to the left end of the tool body 3, the tool tip 5 has an end cutting angle a of 3-5° toward the cutting direction, a spiral cutting edge 6 is fixedly connected to the left side of the front end of the tool body 3, a cutting edge back 7 is fixedly connected to the rear end of the spiral cutting edge 6, and the cutting edge back 7 is 0.3-1.2mm lower than the spiral cutting edge 6;
[0025] Specifically, the material of the cutter body 3 is made of ultra-fine particle cemented carbide. The cemented carbide has high strength, wear resistance, and ultra-fine particles, thus avoiding the problem of easy breakage of the cutter body. The butterfly angle makes it easier for the blade to pass through the material smoothly, thereby facilitating the cutter body to effectively drill holes in the material. The end cutting angle a is 3-5 degrees, which allows better chip removal during engraving. An air avoidance structure is adopted to reduce the friction between the tool and the workpiece, and the engraving surface is smoother. The negative cutting angle of the tool tip 5 allows better strength of the engraving tool tip, and is less prone to chipping and wear. The small helix angle design of the spiral cutting edge 6 allows better chip removal, and a fine thread can be used on the back, which provides better rigidity. During processing, the cutting force is good and the cutter is not burned. The back of the cutting edge 7 is 0.3-1.2 mm lower than the spiral cutting edge 6, which reduces the friction with the workpiece during engraving, resulting in better chip removal and less chip sticking.
[0026] A spiral chip groove 4 is provided at the front end of the cutter body 3. The spiral chip groove 4 is a spiral structure. The angle of the spiral chip groove 4 toward the axial direction is a circumferential back angle b of 10-18°. The back surfaces of the spiral chip groove 4 and the spiral cutting edge 6 are polished.
[0027] Specifically, by adopting the arc-shaped high-capacity spiral chip groove 4 structural design, and the chip groove is a spiral structure, the helix angle can make the actual cutting front angle of the circumferential blade larger, mirror-like, and the grinding process design is particularly suitable for high-efficiency mass production. The processing process is non-stick, smokeless, odorless, and silent. It is a truly green and environmentally friendly engraving tool. By polishing the back surface of the spiral chip groove 4 and the spiral cutting edge 6, a sharp cutting edge structure is formed, and the processed parts have no vibration marks.
[0028] Working principle: The material of the cutter body 3 is made of ultra-fine-grained cemented carbide. The cemented carbide has high strength, wear resistance, and ultra-fine particles, thus avoiding the problem of the cutter body being easily broken. The butterfly angle makes it easier for the blade to pass through the material smoothly, thereby facilitating the cutter body to effectively drill holes in the material. The end cutting angle a is 3-5 degrees, which allows for better chip removal during engraving. The air-avoiding structure reduces the friction between the tool and the workpiece, making the engraving surface smoother. The negative cutting angle of the cutter tip 5 allows for better cutting tip strength, and is less prone to chipping and wear. The small helix angle design of the spiral cutting edge 6 allows for better chip removal. Fine threads can be used on the back, which provides better rigidity during processing. , good cutting force, no knife burning, the back of the cutting edge 7 is lower than the spiral cutting edge 60.3-1.2mm, which reduces the friction with the workpiece during engraving, and the chip removal effect is better, and it is not easy to stick to chips. By adopting the arc-shaped high-capacity spiral chip groove 4 structure design, and the chip groove is a spiral structure, the helix angle can make the actual cutting front angle of the circular blade larger. The mirror surface and the grinding process design are particularly suitable for high-efficiency mass production. The processing process does not stick to the knife, is smokeless, odorless, and silent. It is a truly green and environmentally friendly engraving tool. By polishing the back surface of the spiral chip groove 4 and the spiral cutting edge 6, a sharp cutting edge structure is formed, and the processed parts have no vibration marks.
