By setting a chip removal groove on the surface of the tool tip, this utility model can clean the waste chips generated by milling, avoid accumulation on the surface of the workpiece and affect the rough milling accuracy. At the same time, both the tool shank and the tool tip are made of cemented carbide materials, which can improve the hardness of the tool, and thus improve its service life.
[0005] In the above technical solution, both the tool shank and the tool tip are made of cemented carbide materials, which can improve the hardness of the tool, and thus improve its service life. However, in the actual use process, since the cutting edge, side edge and tool tip are fixedly connected to the tool tip as a whole, they need to be replaced after long-term use and wear. Therefore, we provide a milling cutter with a length adjustment function. Content of the Utility Model
[0006] The utility model provides a milling cutter with a length adjustment function to solve the problem that in the actual use process, since the cutting edge, side edge and tool tip are fixedly connected to the tool tip as a whole, they need to be replaced after long-term use and wear.

The new first cutter block 5 and the first side cutting edge 6 are fixed to the cutter block mounting rod 3 through cutter block fixing screws 7 and side cutting edge fixing screws 8, realizing a modular design. When the first cutter block 5 and the first side cutting edge 6 are worn due to long-term use, these components can be replaced separately without replacing the entire milling cutter, thus reducing the usage cost. Embodiment 2
[0025] In this embodiment, in addition to including all the technical features in Embodiment 1, it further includes: a side cutting edge fixing screw 8 is threadedly installed inside the side cutting edge fixing hole 16 and the side cutting edge mounting hole 17. On the outer surface of the first cutter block 5, a cutter block fixing hole 18 is provided. A cutter block fixing screw 7 is threadedly installed inside the cutter block fixing hole 18 and the cutter block mounting hole 19. On the outer wall of the milling cutter adjustment rod 2, a sealing hole 12 is provided. A sealing screw 4 is threadedly installed inside the sealing hole 12. At the upper end of the milling cutter adjustment rod 2, an adjustment block mounting groove 11 is provided. A length adjustment block 13 is threadedly installed inside the adjustment block mounting groove 11. Through the cooperation of the length adjustment block 13 and the adjustment block mounting groove 11, the length of the milling cutter can be adjusted according to needs, which provides great convenience in practical applications. A rubber ring 15 is sleeved on the lower outer wall of the length adjustment block 13. The length adjustment block 13 and the cutter block mounting rod 3 are of a fixed integral structure. On the outer wall of the length adjustment block 13, an adjustment scale protection groove 20 is provided. On the inner surface of the adjustment scale protection groove 20, an adjustment scale 14 is provided. The design of the adjustment scale 14 and the adjustment scale protection groove 20 enables users to intuitively understand the length adjustment situation of the milling cutter. At the same time, the adjustment scale protection groove 20 can also protect the adjustment scale 14 from being damaged.
[0026] Working principle:
[0027] First, according to the processing requirements, the user adjusts the position of the length adjustment block 13 in the adjustment block installation groove 11, thereby adjusting the overall length of the milling cutter. During the adjustment process, first screw out the sealing screw 4 from the sealing hole 12 to allow air circulation between the adjustment block installation groove 11 and the length adjustment block 13, which facilitates the user to adjust the overall length of the milling cutter. And the user can determine the specific length of the milling cutter by observing the adjustment scale 14. At the same time, the adjustment scale protection groove 20 can also protect the adjustment scale 14 to prevent it from being damaged;
[0028] Secondly, when the first cutter block 5 or the first edge 6 is worn due to long-term use, the user can unscrew the cutter block fixing screw 7 and the edge fixing screw 8 from the edge installation hole 17 and the cutter block fixing hole 18 opened in the cutter edge installation groove 9 and the edge fixing hole 16 and the cutter block installation hole 19, remove the worn first cutter block 5 and the first edge 6 from the cutter block installation rod 3, install new first cutter block 5 and first edge 6, and then fix them with the cutter block fixing screw 7 and the edge fixing screw 8, thereby reducing the use cost;
[0029] Then, through the cooperation of the length adjustment block 13 and the adjustment block installation groove 11, the length of the milling cutter can be adjusted as needed. In practical applications, a rubber ring 15 is sleeved on the outer wall of the lower end of the length adjustment block 13, which increases the tightness between the length adjustment block 13 and the adjustment block installation groove 11, prevents the loosening of the length adjustment block 13 during the processing, and provides great convenience. And during the processing, the heat dissipation groove 10 will help the milling cutter dissipate heat, prevent the performance decline caused by high temperature, and improve the use effect;
[0030] Finally, after the milling cutter is adjusted, screw the sealing screw 4 into the sealing hole 12 to make the air in the adjustment block installation groove 11 in a static state, improve the stability between the length adjustment block 13 and the adjustment block installation groove 11 during work, and then fix the milling cutter adjustment rod 2 on the lathe through the milling cutter clamping block 1, which is convenient for the user to use.
