  • the second screw hole 14 may be configured to be located closer to the rear end 10b of the holder 10 than the first screw hole 13.
  • This configuration reduces the risk of chips generated during cutting entering the second screw hole 14. That is, during cutting, the cutting tool 1 is attached to the spindle of the processing machine so that the tip 10a of the holder 10 faces vertically downward. Therefore, the generated chips move vertically downward due to gravity. With the above configuration, the second screw hole 14 is more likely to be located vertically above the cutting edge of the cutting insert 20, making it difficult for chips to enter the second screw hole 14.
  • the second screw hole 14 may be configured to be located closer to the rear end 10b of the holder 10 than the cutting insert 20. In such a configuration, it becomes even more difficult for cutting chips to get into the second screw hole 14.

  • Fig. 8 is a schematic diagram showing a state during cutting processing in the cutting tool 1 according to an embodiment of the present disclosure.
  • the method for replacing the cutting insert 20 may include steps A, B, C, D, E, and F.

  • Step B is a step of removing the cleaning screw 40 from the second screw hole 14 (see FIG. 3).
  • Step C is a step of removing the used cutting insert 20 from the chip pocket 11 (see FIG. 3).
  • step D the cleaning screw 40 removed from the second screw hole 14 is attached to the first screw hole 13 (see FIG. 6).
  • the coolant CL is supplied to the flow path 15 (see FIG. 6).
  • step F an unused cutting insert 20 is attached to the chip pocket 11.
  • the method for replacing the cutting insert 20 may include a step G of attaching the clamp screw 30 removed from the first screw hole 13 to the second screw hole 14 (see FIG. 6).
  • the cleaning screw 40 removed from the second screw hole 14 is attached to the first screw hole 13 from which the used cutting insert 20 has been removed, and in this state, coolant CL is supplied to the flow path 15.
  • the coolant CL is discharged to the outside of the holder 10 through the through hole 41.
  • chips containing fine iron powder and the like that are attached to the inside and periphery of the chip pocket 11 after the used cutting insert 20 has been removed can be removed by the coolant CL discharged from the cleaning screw 40.
  • chips that have entered the chip pocket 11 can be efficiently removed as part of the operation of the cutting tool 1, without the need for work such as spraying cleaning liquid or gas from the outside.
  • the risk of the device becoming complicated can be reduced.
  • a supply port 42 is provided at the tip 40a and a discharge port 43 is provided on the outer peripheral surface 40b, so that the coolant CL is discharged laterally from the outer peripheral surface 40b of the cleaning screw 40, as shown in the example of Figure 7.
  • the coolant CL can be effectively supplied into the chip pocket 11 from the cleaning screw 40 attached to the first screw hole 13. This allows the discharge of the coolant CL to effectively remove chips adhering to the chip pocket 11.
  • the discharge port 43 by configuring the discharge port 43 to be smaller than the supply port 42, the ejection pressure of the coolant CL when it is discharged is increased, thereby improving the effectiveness of chip removal both when replacing the cutting insert 20 and when cutting processing is performed.
  • first outlet 43A and the second outlet 43B are same size, it is possible to reduce variation in the amount of coolant CL discharged, which depends on the orientation of the cleaning screw 40 when attached to the first screw hole 13 or the second screw hole 14.
  • the coolant CL can be ejected more effectively in a shower-like manner, improving cleaning performance.
  • the clamp screw 30 does not have a through hole 41 connected to the flow path 15 like the cleaning screw 40, and is solid in structure, so that the coolant CL is less likely to be discharged through the clamp screw 30.
  • the clamp screw 30 attached to the first screw hole 13 is solid and blocks the first screw hole 13 which is connected to the flow path 15. This allows the coolant CL supplied from the flow path 15 to be sent to the through hole 41 of the cleaning screw 40 attached to the second screw hole 14, allowing more coolant CL to be discharged toward the cutting area.
  • the cutting tool 1 is attached to the spindle of the processing machine so that the tip 10a of the holder 10 faces vertically downward (see FIG. 11). Therefore, as shown in the example of FIG. 1, by configuring the second screw hole 14 to be located closer to the rear end 10b of the holder 10 than the first screw hole 13, the coolant CL discharged from the cleaning screw 40 during cutting can be effectively directed toward the cutting area located vertically downward. This increases the effectiveness of chip removal by the coolant CL discharged from the second screw hole 14 through the cleaning screw 40 during cutting.
  • the opening of the second screw hole 14 may be configured to be located forward in the rotational direction of the rotation shaft RS than the opening of the first screw hole 13, as in the example shown in FIG. 1. This also allows the coolant CL discharged from the cleaning screw 40 to be effectively directed toward the cutting site located behind in the rotational direction during cutting.
  • Figures 9 and 10 are schematic diagrams for explaining another method for replacing the cutting insert according to the embodiment of the present disclosure.
  • the process may include a step H in which the clamp screw 30 removed from the first screw hole 13 in the above-mentioned step A is attached to the third screw hole 16.
  • the method may include a step G' in which the clamp screw 30 is removed from the third screw hole 16 and the removed clamp screw 30 is attached to the second screw hole 14 instead of the above-mentioned step G.
  • this allows the second screw hole 14 connected to the flow path 15 to be blocked by the solid clamp screw 30 when replacing the cutting insert 20, allowing more coolant CL to be supplied to the through hole 41 of the cleaning screw 40 attached to the first screw hole 13.
  • Fig. 11 to Fig. 13 are schematic diagrams for explaining a method for manufacturing a machined product according to an embodiment of the present disclosure.

  • the manufacturing method of the machined product according to the embodiment of the present disclosure is a manufacturing method for manufacturing the machined product M by cutting the workpiece W using the cutting tool 1, and may include a first step, a second step, and a third step.
  • the first step is a step of rotating the cutting tool 1.
  • the second step is a step of bringing the rotating cutting tool 1 into contact with the workpiece W.
  • the third step is a step of separating the cutting tool 1 from the workpiece W.
  • Examples of the material of the workpiece W include aluminum alloy, stainless steel, carbon steel, alloy steel, cast iron, and non-ferrous metal.
  • the specific content of the manufacturing method of the machined product according to the embodiment of the present disclosure is as follows.
  • the cutting tool 1 is rotated in the rotation direction T while being moved in the direction of the arrow FD to approach the workpiece W. Then, the cutting insert 20 of the rotating cutting tool 1 is moved in the direction of the arrow FD while being brought into contact with the workpiece W. As a result, the cutting tool 1 cuts the workpiece W, and as shown in the example in Figure 13, a machined surface Wf is formed on the workpiece.
  • the cutting tool 1 is further moved in the direction of the arrow FD to separate it from the workpiece W. This completes the cutting of the workpiece W, and a machined product M can be produced, which is the workpiece W that has been machined.
