[0002] A milling cutter is a rotating cutting tool used for milling operations. It has one or more cutting teeth. During operation, each cutting tooth cuts off the excess material of the workpiece in turn. Among them, the T-slot milling cutter is a milling tool specifically designed for machining T-slots. This milling cutter is widely used in fields such as mechanical manufacturing.

[0003] A search revealed that publication number CN214236451U discloses a T-slot end mill, which uses a cylindrical tool holder as its main body and has multiple cutting edges fixed on it. These cutting edges are divided into multiple cutting groups, with the cutting edges in different groups located at different positions along the axial direction of the tool holder. Multiple cutting edges within the same cutting group are positioned identically along the axial direction, and the cutting edges in adjacent cutting groups partially overlap along the axial direction. This T-slot end mill reduces cutting resistance and tool vibration during use, effectively preventing chatter marks in the machined slots and improving the quality of the T-slots. However, after prolonged use, if some of the cutting edges of this T-slot end mill are significantly worn, the entire tool holder needs to be removed for replacement. At this point, even the less worn cutting edges cannot be used, resulting in high maintenance and replacement costs for this T-slot end mill. Utility Model Content

[0004] Given that the existing technology has the problem that after a long period of use, if some of the cutting tips of the T-slot end mill are worn out, the entire cutter shank needs to be removed and replaced, and the less worn cutting tips cannot be used anymore, the maintenance and replacement cost of the T-slot end mill is high.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-feed-rate T-slot end mill with anti-chipping properties, comprising: Shaft, connector, keyway, wherein the connector is fixed to one end of the shaft; The keyways are symmetrically arranged on both sides of the connector; Fixed components, cooling components, and water supply components; The fixing component is fixed to the bottom end of the shaft; The cooling assembly is located inside the shaft.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Example 1: Please refer to Figures 1-3 This is the first embodiment of the present invention, which provides a high-feed-rate T-slot end mill with anti-chipping properties, comprising: Shaft 1, connector 4, keyway 5, connector 4 is fixed to one end of shaft 1; Keyways 5 are symmetrically located on both sides of connector 4; Fixing component 2, cooling component 3, and water supply component 6; Fixing component 2 is fixed to the bottom end of shaft 1; Cooling assembly 3 is located inside shaft 1; The water conveying component 6 is installed on the top circumferential surface of the shaft 1.

[0018] Specifically, the fixing component 2 includes a cutter body 21, a fixing seat 22, a mounting groove 23, an alloy cutter head 24, a fixing hole 25, a fixing rod 26, and an internal hexagonal groove 27. The cutter body 21 is fixed to the bottom end of the shaft 1. The fixing seat 22 is evenly fixed on the circumference of the cutter body 21. The fixing seat 22 has a mounting groove 23 on its side. The alloy cutter head 24 is fastened inside the mounting groove 23. The fixing hole 25 is symmetrically opened inside the mounting groove 23. The fixing rod 26 is symmetrically inserted through the side of the alloy cutter head 24. One end of the fixing rod 26 passes through the alloy cutter head 24 and rotates through the inside of the fixing hole 25. The fixing rod 26 is fixedly connected to the fixing hole 25 by a threaded fit. The fixing rod 26 has an internal hexagonal groove 27 at one end.

[0019] Furthermore, the detachable cutter head structure composed of the fixing rod 26 and the alloy cutter head 24 allows for quick replacement after the cutter head wears down, preventing it from affecting milling operations. At the same time, by replacing the alloy cutter head 24, the cost of milling cutter maintenance and replacement can be reduced.

[0020] In use, the alloy cutter head 24 is fastened into the mounting groove 23 on the side of the fixed base 22, and the fixing rod 26 is symmetrically inserted into the inside of the alloy cutter head 24. Then, with the cooperation of the internal hexagonal groove 27, the fixing rod 26 is rotated so that it is fixedly connected to the fixing hole 25 on the side of the fixed base 22 through thread engagement, thereby completing the installation of the alloy cutter head 24. At this time, the shaft 1 can be installed with the cooperation of the connector 4. The milling equipment drives the cutter body 21 on the bottom side of the shaft 1 to rotate, thereby performing milling.

[0021] In summary, through the structure of the fixing component 2, the alloy cutter head 24 can be fixedly installed on the side of the fixing seat 22 by the cooperation of the fixing rod 26 and the fixing hole 25. At this time, the shaft 1 can drive the cutter body 21 to rotate, causing the alloy cutter head 24 to perform milling. If the alloy cutter head 24 is worn too much during the processing and cannot be used normally, it can be quickly removed and replaced with the cooperation of the internal hexagonal slot 27, which can prevent the milling process from being affected and reduce the cost of milling cutter maintenance and replacement.

[0022] Example 2: Please refer to Figures 4-5 This is the second embodiment of the present utility model.

[0023] Specifically, the cooling assembly 3 includes a cooling groove 31, a cavity 32, a through hole 33, and a water spray hole 34. The cooling groove 31 is located at the center of the inner side of the shaft 1. Water spray holes 34 are evenly distributed on the bottom circumferential surface of the shaft 1. A cavity 32 is provided on the inner side of the cutter body 21. The cavity 32 is connected to the inner side of the cooling groove 31. Through holes 33 are evenly distributed on the circumferential surface of the cutter body 21. The through holes 33 are connected to the inner side of the cavity 32.

[0024] Furthermore, the structure of the cooling tank 31 allows coolant to be delivered to the cutter body 21 during milling, preventing overheating and embrittlement of the cutter head, thereby extending the service life of the cutter head.

[0025] Specifically, the water supply component 6 includes a limiting platform 61, a housing 62, a water supply hole 63, a threaded seat 64, and a sealing ring 65. The limiting platform 61 is fixed on the top circumferential surface of the shaft 1. The housing 62 is rotatably installed inside the limiting platform 61. A sealing ring 65 is fitted between the contact surface of the housing 62 and the shaft 1. Water supply holes 63 are evenly opened on the circumferential surface of the shaft 1, and the water supply holes 63 are located inside the housing 62. A threaded seat 64 is fixed on the circumferential surface of the housing 62, and the threaded seat 64 communicates with the inside of the housing 62.

[0026] Furthermore, through the structure of the housing 62, the threaded seat 64 is fixedly connected to the cooling source using a conduit, thereby delivering coolant to the inside of the shaft 1 to cool the cutting head during the milling process, thus improving the efficiency of the milling cutter.

[0027] In use, the threaded seat 64 is fixedly connected to the cooling source using a conduit. When the milling machine drives the shaft 1 to rotate, coolant is supplied to the inside of the housing 62 through the cooling source. At this time, the coolant inside the housing 62 is supplied to the inside of the cooling groove 31 inside the shaft 1 through the water inlet 63, so that it is sprayed out onto the surface of the cutter body 21 through the water spray hole 34 on the circumferential surface of the shaft 1, thereby cooling the cutter body 21 and the carbide cutter head 24. At the same time, the coolant is supplied to the inside of the cavity 32 and sprayed out through the through hole 33. This allows the coolant to cool the cutter body 21 and the carbide cutter head 24 while flushing out the cutting chips, preventing the accumulation of chips from affecting the milling quality of the milling cutter, and keeping the carbide cutter head 24 within a suitable temperature range to prevent the carbide cutter head 24 from chipping or being damaged.

[0028] In summary, through the structure of the cooling component 3 and the water supply component 6, the milling chips can be flushed away while cooling, preventing them from affecting the milling quality of the milling cutter. At the same time, with the cooperation of the housing 62, the normal operation of the milling cutter can be maintained while supplying coolant, keeping the milling cutter within a suitable temperature range and extending its service life.
