Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting instrument technology, and in particular to a cutting tool. Background Technology
[0002] Cutting tools are tools used for machining materials such as metals, plastics, and wood. They remove material from the surface through mechanical cutting, bringing the workpiece to the desired shape and size. Common cutting tools include turning tools, milling cutters, drill bits, planing tools, and saw blades. Cutting tools are typically made of high-hardness, high-wear-resistant materials, such as high-speed steel, cemented carbide, or ceramics, to ensure cutting efficiency and service life. The geometry and angle design of the tool directly affect the cutting effect and machining quality, making it an indispensable piece of equipment in machining.
[0003] Most disc-shaped cutting tools in the prior art are solid. When the cutting tool comes into contact with the workpiece, the cutting fluid cannot reach the contact point between the cutting tool and the workpiece to effectively cool the cutting edge of the cutting tool, resulting in a limited cutting edge life. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that most disc-shaped cutting tools in the prior art are solid, and when the cutting tool comes into contact with the workpiece, the cutting fluid cannot reach the contact position between the cutting tool and the workpiece to effectively cool the cutting edge of the cutting tool, resulting in a limited cutting edge life. Therefore, this invention proposes a cutting tool.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cutting tool includes a cutting disc, a cutting edge, and a center cylinder. The cutting disc has a circular array of cutting edges on its sidewalls. The center cylinder is fixedly installed at the center of the top of the cutting disc. The center cylinder has a mounting hole on its side. The cutting disc has a circular array of inlet holes on its top. The inlet holes are provided with a drainage structure inside the cutting disc to introduce cutting fluid to the side of the cutting edge.
[0007] Optionally, the flow-guiding structure includes a first flow channel, and the cutting edge includes a short inclined surface and a long inclined surface, with the first flow channel formed on the side of the long inclined surface of the cutting edge.
[0008] Optionally, the ends of the first guide channels of adjacent cutting edges are interconnected and connected to the same inlet hole, and the diameter of the first guide channel is smaller than the diameter of the inlet hole.
[0009] Optionally, the length of the short inclined plane of the cutting edge is half the length of the long inclined plane, and the material of the cutting edge is high-speed steel.
[0010] Optionally, the inside of the inlet hole is polished into a smooth surface, and the number of inlet holes is half the number of the first guide channels.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. This utility model has an inlet hole at the top of the cutting tool, which can introduce most of the cutting fluid into the first guide channel opened on the side of the cutting edge. The cutting fluid is introduced into the contact position between the cutting tool and the workpiece. The cutting fluid is guided through the first guide channel, which helps to remove chips in time, avoid the impact of chip accumulation on the machining effect, and maintain cutting stability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-2 A cutting tool includes a cutting disc 3, cutting edges 5, and a center cylinder 1. The cutting disc 3 has a circular array of cutting edges 5 on its side wall. The center cylinder 1 is fixedly installed at the top center of the cutting disc 3. The center cylinder 1 has a mounting hole 2 on its side. The center cylinder 1 at the center of the cutting disc 3 is inserted into the tool holder and is then inserted into the mounting hole 2 and the hole reserved in the tool holder by bolts in sequence, so that the entire cutting tool is finally fixed to the output end of the power source.
[0018] The top of the cutting disk 3 has a circular array of inlet holes 4. The inlet holes 4 are provided with a flow-guiding structure inside the cutting disk 3 to introduce cutting fluid to the side of the cutting edge 5. The flow-guiding structure includes a first flow channel 6. The cutting edge 5 includes a short inclined surface 52 and a long inclined surface 51. The first flow channel 6 is opened on the side of the long inclined surface 51 of the cutting edge 5.
[0019] The ends of the first guide channels 6 of adjacent cutting edges 5 are connected to each other and connected to the same inlet hole 4. The diameter of the first guide channel 6 is smaller than the diameter of the inlet hole 4. The length of the short inclined surface 52 of the cutting edge 5 is half the length of the long inclined surface 51. The material of the cutting edge 5 is high-speed steel. The inside of the inlet hole 4 is ground into a smooth surface. The number of inlet holes 4 is half the number of the first guide channels 6.
[0020] The specific implementation steps and principles of this utility model are as follows:
[0021] Insert the center cylinder 1 at the center of the cutting disc 3 into the tool holder, and then insert it into the mounting hole 2 and the hole reserved in the tool holder in sequence by bolts. When the cutting disc 3 rotates, most of the cutting fluid poured into the top of the cutting disc 3 is introduced into the first guide channel 6 opened on the side of the cutting edge 5 through the inlet hole 4. The cutting fluid is introduced into the contact position between the cutting edge 5 and the workpiece. The cutting fluid is guided by the first guide channel 6, which helps to remove chips in time.
