Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting tools, in particular to a non-standard forming tool for efficiently processing avoidance workstations. Background Art

[0002] In the field of metal cutting tool technology, especially when processing IC components, we often face the challenge of complex structures, especially those stations that need to be avoided. These stations are often difficult to process normally due to space limitations or structural complexity, such as Figure 1 and Figure 2 As shown in Figure 1, the four interfering machining stations 11 of the part 1 to be machined have interference points 12 along the machining route. The traditional solution is to use a tool grinder to sharpen the tool to reduce the diameter of the tool at the interfering parts, so that it can enter and machine these avoidance stations. However, this method has many shortcomings:

[0003] Firstly, the tool resharpening process is time-consuming, labor-intensive and inefficient. The tool needs to be precisely resharpened to ensure it can accurately adapt to the shape and size of the avoidance station. This process is not only time-consuming but also requires a high degree of professional skills.

[0004] Secondly, the overall structural strength of the tool will be seriously affected after grinding. As the diameter of the tool is reduced, its ability to withstand cutting forces will also be reduced accordingly, which may make the tool more susceptible to damage during processing and even cause safety accidents.

[0005] Furthermore, traditional machining methods also suffer from significant shortcomings in terms of efficiency and quality. Due to the limited machining parameters of reground tools, machining speed and production efficiency cannot be fully utilized. Furthermore, tool wear and instability make it difficult to ensure consistent product quality, directly impacting the precision and performance of semiconductor equipment.

[0006] Therefore, there is an urgent need for a new type of tool design to solve the problem of normal processing in special workstations that need to be avoided. Utility Model Content

[0007] In order to solve the above problems, the utility model provides a non-standard forming tool for efficient processing avoidance station. The non-standard forming tool for efficient processing avoidance station has strong versatility and can effectively replace most traditional grinding tool processing avoidance stations, reduce the frequency of tool grinding, and reduce the cost of manual grinding; the overall structural strength of the non-standard forming tool is better than that of the tool after grinding, the processing parameters can be greatly improved, the product production efficiency and processing quality are improved, and the processing cost is reduced.

[0008] The technical solution of the utility model is as follows:

[0012] The diameter of the shank section has a tolerance class of h6.

[0013] The diameter of the avoidance section is 7 mm.

[0029] like Figure 3 As shown, the non-standard forming tool used for efficient machining of the avoidance station mainly includes three parts: the shank section 2, the avoidance section 3 and the tool head section 4.

[0030] The total length of the tool is 120 mm, of which the total length of the avoidance section 3 and the tool head section 4 is 73 mm, and the length of the tool head section 4 is 50 mm.

[0031] Shank segment 2 has a diameter of 16 mm and a tolerance of H6. The shank segment is designed to provide stable clamping and rotation, ensuring the stability and precision of the tool during machining.

[0032] The diameter of the avoidance section 3 is 7mm with a tolerance of ±0.1mm. The avoidance section is designed to adapt to the interference on the workpiece, avoiding interference with the workpiece by reducing the diameter while maintaining sufficient structural strength.

[0033] The tool head section 4 features two cutting edges, each with a diameter of 14.22mm and a length of 10mm, with a tolerance of ±0.02mm. The cutting edges are designed to provide efficient cutting performance, while the widened chip flutes prevent chip sticking during machining. To enhance tool strength and smooth transitions, transition tapers are provided between the cutting edges and the run-off section 3, as well as between the shank section 2 and the run-off section 3.

[0034] The tool of this embodiment is made of high-strength and high-wear-resistant hard alloy material to ensure the durability and stability of the tool during the processing.

[0035] like Figure 1 and Figure 2 As shown, there are four countersunk holes on the workpiece that are blocked by the upper surface stations. These stations are the stations that need to be avoided.

[0036] CAM software is used for programming to plan the tool path based on the shape and size of the workpiece, as well as the location and size of the avoidance station to be processed. This ensures that the tool can efficiently remove material in the avoidance area of ​​the workpiece while avoiding interference with other parts of the workpiece.

[0037] Custom forming tools are installed on CNC machine tools, and the tool's control system controls the tool's machining path and cutting parameters. During machining, the tool follows the predetermined path, efficiently removing material from workpiece clearances. Furthermore, the optimized tool design, coupled with precise control using CAM software, ensures consistent, high-precision finished products.

[0038] The non-standard forming tool of this embodiment and its method of use can efficiently produce workstations requiring avoidance while maintaining the tool's structural strength and cutting performance. Compared to traditional tool grinding methods, the tool of this embodiment has the following advantages: It is highly versatile and can effectively replace most traditional tool grinding workstations, reducing tool grinding frequency and labor costs; its overall structural strength is superior to that of tools after grinding, and processing parameters can be significantly improved, thereby improving product production efficiency, processing quality, and processing costs.
