Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting tool technology, and in particular to a roughing and finishing milling cutter for machining steel parts. Background Technology
[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. Milling cutters are widely used in mechanical processing and production. With the cooperation of different processing equipment and fixtures, they can process any part of the workpiece to achieve the product's technological requirements.
[0003] Milling cutters commonly found in the market are divided into roughing and finishing cutters, and semi-finishing cutters for some special applications. However, the tools are mostly processed separately, which is common and simple to design and program, making it easy for programmers to learn and operate. But as product requirements become more demanding and the types of holes to be processed become more diverse, when the existing equipment does not have enough workstations to accommodate more tools to meet the processing requirements, it is necessary to use two or more machines or purchase new equipment with more tool positions for processing, resulting in low processing efficiency. Furthermore, processing by separate processes or machines can easily lead to problems such as tool marks and vibration marks, and currently no effective solution has been proposed. Utility Model Content
[0004] Purpose of the utility model: To provide a roughing and finishing milling cutter for machining steel parts, so as to at least solve one of the problems existing in the prior art.
[0005] Technical solution: A roughing and finishing milling cutter for machining steel parts, comprising:
[0006] Handle; and
[0007] The cutting edge of the cutting tool is circumferentially disposed around one end of the tool holder along the axial direction of the tool holder; the cutting edge of the cutting tool includes: a first cutting edge and a second cutting edge, which are arranged in a circumferential manner with a gap between them.
[0008] The first and second machining cutting edges are integrated and disposed at one end of the tool holder to form a roughing and finishing milling cutter for machining steel parts.
[0009] Preferably, a chip removal groove is provided in a ring between adjacent first and second machining cutting edges.
[0010] Preferably, the first machining edge is a roughing edge, and the second machining edge is a finishing edge.
[0011] Preferably, the outer ring of the roughing edge forms a first cutting edge diameter, and the outer ring of the finishing edge forms a second cutting edge diameter.
[0012] Wherein, the first cutting edge diameter is smaller than the second cutting edge diameter.
[0013] Preferably, the accuracy of the roughing cutting edge is 0.05 lower than that of the finishing cutting edge.
[0014] Preferably, there are two roughing cutting edges and two finishing cutting edges.
[0015] Preferably, the two roughing cutting edges are each provided with a wave-shaped cutting edge.
[0016] Preferably, the wave blade is formed by a number of R angles in a periodic cycle.
[0017] Preferably, the height of adjacent R-angles is 0.4 mm, and the distance between adjacent R-angles is 1.6 mm.
[0018] Preferably, the two finishing edges are continuously ground edges.
[0019] Beneficial Effects: In this embodiment, the roughing and finishing cutting edges are integrally formed. By integrating the first, second, and third disc milling cutters along the axial direction of the tool holder and combining the first and second machining cutting edges into one piece at one end of the tool holder, a roughing and finishing milling cutter for machining steel parts is formed. This achieves the purpose of integral forming of the roughing and finishing cutting edges of the milling cutter, thereby improving machining accuracy, machining efficiency, machining quality, and reducing machining costs. Furthermore, it solves the technical problem that as product requirements become increasingly stringent and the number of hole shapes in the machined parts increases, when there are no extra workstations on the existing equipment to accommodate more cutting tools to meet the machining requirements, it is necessary to use two or more machines or purchase new equipment with more tool positions for machining, resulting in low machining efficiency and the easy generation of tool marks and vibration marks after machining in separate processes or on separate machines.

[0032] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.
[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] like Figure 1-4 As shown, this application relates to a roughing and finishing milling cutter for machining steel parts. Figure 1As shown, the roughing and finishing milling cutter for machining steel parts includes: a tool holder 10; the tool holder 10 refers to the tool shank, which can achieve good clamping and fixing effects, thereby achieving good cooperation with other components, and thus providing a foundation and guarantee for subsequent precise cutting.
[0035] The cutting edge 20 of the cutting tool is circumferentially arranged around one end of the tool holder 10 along the axial direction; the cutting edge 20 of the cutting tool includes: a first cutting edge 201 and a second cutting edge 202, the first cutting edge 201 and the second cutting edge 202 are arranged in a circumferential manner at intervals; this can ensure a good cutting effect.
[0036] The first machining cutting edge 201 and the second machining cutting edge 202 are integrated into one end of the tool holder 10 to form a roughing and finishing milling cutter for machining steel parts. By seamlessly integrating the two cutting edges into one end of the tool holder 10 according to a preset shape, the roughing and finishing cutting processes can be smoothly connected. The integrated design of the end of the tool holder 10 ensures the overall stability of the tool, reduces tool vibration during the cutting process, and improves machining stability and surface quality.
[0037] This application has the following beneficial effects:
[0038] Processing efficiency: Roughing and finishing can be completed with a single installation and a single processing path, effectively reducing tool change time.
[0039] Cost savings: By reducing the types and quantities of cutting tools, tool costs and maintenance expenses can be effectively saved.
[0040] Improved machining accuracy: The integrated tool design ensures the consistency of the machining path, which helps to improve machining accuracy, especially by reducing possible workpiece clamping errors.
[0041] As can be seen from the above description, this application achieves the following technical effects:
[0042] In this embodiment, a method of integral forming of roughing and finishing cutting edges is adopted. By integrating the first, second, and third disc milling cutters along the axial direction of the tool holder 10 and integrating the first machining cutting edge 201 and the second machining cutting edge 202 into one piece at one end of the tool holder 10, an integral roughing and finishing milling cutter for machining steel parts is formed. This achieves the purpose of integral forming of the roughing and finishing cutting edges of the milling cutter, thereby realizing the technical effects of improving machining accuracy, machining efficiency, machining quality, and reducing machining costs. Furthermore, it solves the technical problem that as product requirements become increasingly demanding and the number of hole shapes in the machined parts also increases, when there are no extra workstations on the existing equipment to accommodate more cutting tools to meet the machining requirements, it is necessary to use two or more machines or purchase new equipment with more tool positions for machining, resulting in low machining efficiency and the easy generation of tool marks and vibration marks after machining in separate processes or on separate machines.
[0043] Furthermore, a chip removal groove 30 is provided in a ring between adjacent first machining cutting edges 201 and second machining cutting edges 202. It can be understood that by providing the chip removal groove 30, the chips generated during cutting can be guided away from the cutting edge, reducing the interference of chip accumulation on the cutting effect of the cutting edge, thereby ensuring stable cutting of both roughing and finishing cutting edges.
[0044] Reduce heat accumulation: Since a lot of heat is generated when cutting steel, the chip groove 30 can effectively disperse the heat in the cutting area, prevent the cutting edge from overheating, and extend the tool life.
[0045] like Figure 3-4 As shown, the first machining edge 201 is a roughing edge, and the second machining edge 202 is a finishing edge. This ensures the achievement of the corresponding cutting function.
[0046] like Figure 2 As shown, the outer ring of the roughing edge forms a first cutting edge diameter 2022, and the outer ring of the finishing edge forms a second cutting edge diameter 2021;
[0047] Wherein, the first cutting edge diameter 2022 is smaller than the second cutting edge diameter 2021. It can be understood that this ensures good cutting performance.
[0048] Furthermore, the precision of the roughing edge is 0.05 lower than that of the finishing edge. It can be understood that the diameter of the roughing edge is 0.05 lower than the outer diameter of the finishing edge, and this 0.05 allowance is precisely satisfied by the finishing edge.
[0049] Furthermore, the number of the roughing cutting edge and the finishing cutting edge are two each.
[0050] like Figure 3As shown, each of the two roughing cutting edges is provided with a wave-shaped cutting edge 2011. It can be understood that by providing the wave-shaped cutting edge 2011, the cutting material can be easily broken.
[0051] Furthermore, the wave blade 2011 is formed by a number of R angles in a periodic cycle. It is understood that this enables continuous cutting.
[0052] Furthermore, the height of adjacent radius (R-angle) is 0.4 mm, and the distance between adjacent radius (R-angle) is 1.6 mm. This ensures precise cutting results.
[0053] Furthermore, both of the aforementioned finishing edges are continuously precision ground edges.
[0054] Furthermore, the outer surface of the tool is coated with a brownish-red coating. This is understood to improve the tool's wear resistance, corrosion resistance, and high-temperature oxidation resistance, thereby extending tool life and enhancing machining performance. The coating typically employs titanium aluminum nitride (TiAlN), titanium aluminum nitride (AlTiN), or other advanced composite coatings to ensure superior performance when machining high-strength materials such as steel.
[0055] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
