[0002] In the field of machining, NPT (National Pipe Thread) threads are a widely used thread standard, commonly used in pipe connections, valve installation, and other applications. Its machining accuracy and efficiency have a significant impact on overall product quality and production costs. Traditional NPT thread machining methods often use tools such as taps and dies for manual or mechanical tapping. However, these methods often suffer from low efficiency and difficulty in ensuring machining accuracy when faced with high-precision, high-volume production requirements.
[0003] In addition, traditional processing tools, especially the tool grooves on the tool, are prone to wear after long-term use. Once the wear is severe, the entire tool needs to be replaced, which not only increases production costs, but also affects production progress and efficiency.

[0027] The fixing component is arranged on the thread cutter 5 and is used to fix and limit the thread cutter 5.
[0028] Furthermore, a plurality of mounting ends 3 are each provided with a mounting groove 6 for mounting.
[0029] Furthermore, a second mounting seat 7 that matches the bottom of the thread cutter 5 is fixedly installed at a position corresponding to the mounting groove 6, and the second mounting seat 7 is plugged into the inside of the mounting groove 6. The arrangement of the mounting groove 6 and the second mounting seat 7 not only simplifies the installation process and improves the assembly efficiency, but also ensures the stability of the thread cutter 5 during high-speed rotation and work through the dual methods of plug-in and fixed installation, effectively preventing the thread cutter 5 from loosening or falling off, thereby extending the service life of the NPT thread milling cutter and improving the processing accuracy and safety.
[0030] Furthermore, fixed side bars 8 for strengthening the connection are fixedly installed on both sides of the second mounting seat 7, and slots 9 that match the fixed side bars 8 are opened at the positions of the mounting ends 3 corresponding to the fixed side bars 8. Through the setting of the fixed side bars 8 and the slots 9, not only the overall structural rigidity of the NPT thread milling cutter is improved, but also it can effectively resist the vibration and deformation caused by the cutting force in a complex or high-load processing environment, thereby ensuring the stability and accuracy of the processing and reducing the failure rate caused by connection failure.
[0031] Furthermore, a chip groove 10 for chip removal is provided between the two sets of mounting ends 3. The setting of the chip groove 10 provides a smooth discharge channel for metal chips generated during the cutting process, effectively avoiding the accumulation of chips around the tool, and reducing the problems of increased cutting force, accelerated tool wear and decreased machining surface quality caused by chip blockage. At the same time, good chip removal performance also improves cutting efficiency, allowing the NPT thread milling cutter to maintain an efficient and stable working state during long-term continuous processing.
[0032] Furthermore, screws 11 are fixedly installed on both sides of the mounting end 3, and the mounting end 3 and the fixed side strip 8 are fixedly connected together by the screws 11.

[0033] Furthermore, the fixing component includes an extension plate 12 and a slot 13. The end of the second mounting seat 7 is fixedly installed with an extension plate 12 for connection. A slot 13 that fits with the extension plate 12 is opened inside the mounting end 3 at a position corresponding to the extension plate 12. The tool handle 2 is fixedly connected to the position corresponding to the extension plate 12 and the slot 13 with a detachable screw. The screw passes through the extension plate 12 and the slot 13 and fixes them together. Through the setting of the fixing component, not only the structure of the fixing component is simplified, but also the installation and disassembly process of the thread cutter 5 is made more convenient and flexible. At the same time, the tightening effect of the screw is utilized to ensure high-precision positioning of the thread cutter 5 after installation, preventing processing errors caused by loosening. In addition, the detachable design also facilitates users to quickly replace cutting parts of different specifications or wear according to specific processing requirements, thereby improving the versatility and economy of the NPT thread milling cutter.
[0034] Instructions
[0035] After the second screw thread is cut, the second thread cutter 5 and the second mounting seat 7 are fixed to the bottom of the thread cutter 5, and the second mounting seat 7 and the extension plate 12 are fixed to the end of the second mounting seat 7. The extension plate 12 is also inserted into the slot 13. The tool holder 2 and the slot 13 are fixed by the screw, and the mounting end 3 and the fixed side strip 8 are fixed by the screw 11 to complete the overall installation and fixation. When the thread cutter 5 is worn or needs to cut different threads, the screws 11 and the screws can be removed. Then, the thread cutter 5, the second mounting seat 7 and the extension plate 12 are pulled out from the mounting end 3 as a whole, and the above operation is repeated to complete the overall installation. Through the mutual cooperation between the above structures, the threaded part on the tool can be replaced as needed during use, thereby facilitating the use of various thread processing and facilitating the replacement of damaged thread blade parts, thereby reducing maintenance costs, making it more convenient to use during milling cutter processing, and more practical.
