- the cutting insert 13 or 15 which is fastened to the insert mounting seat portion 11a of the milling cutter 1 on which the circular sheet protruding member 11b is formed is irrespective of the position of both insert mounting seat portions 11a. Since a common coupling structure is formed, incorrect mounting of the cutting insert may be made, thereby causing a loss due to component breakage of the cutting insert and the slot milling cutter, resulting in inconvenience in use.
- the present invention has been made in order to solve the above-mentioned conventional problems, there is a distinction between the left and right shape of the cutting inserts respectively coupled to both sides of the milling cutter body, the structure that the cutting insert is not fastened to the insert mounting sheet portion on the opposite side It is an object of the present invention to provide an insert for slot milling to prevent chaos from occurring during use of the user.
- a clearance angle in the cutting insert itself a step is not formed in the valley tip end surface of the slot after the slot is processed, and a flat surface is maintained, and at the same time, a radius R shape is formed at the cutting edge of the cutting insert.
- the purpose is to provide a slot milling insert that can improve the processing quality of the slot, thereby increasing customer satisfaction.
- a plurality of cutting inserts are provided around the slot milling cutter body, one of every two cutting inserts protrudes against one side of the milling cutter body, The other one has a structure protruding with respect to the opposite side of the milling cutter body, and each of the two cutting inserts are formed in a different structure so as to prevent incorrect mounting on the insert mounting seat portions provided on both sides of the milling cutter body, respectively. It is characterized by one.
- an insert groove is formed on a bottom mounting surface in contact with the insert mounting seat of the milling cutter, and the insert groove is preferably formed in a polygonal recess shape.
- a through hole is formed on an inner central portion thereof, and a spiral is formed on an inner circumferential surface of the through hole, so that the sheet protruding member has a stable coupling structure by fastening by screwing.
- the cutting insert may be such that the cutting edge portion of one cutting insert of every two cutting inserts is rounded.
- the cutting insert of the present invention is a cutting edge portion is formed on one side along the body circumference of the rectangular parallelepiped, the center is formed with a through hole for insert coupling, at least one groove shape on the protruding surface portion of the opposite side of the insert binding surface It is desirable to provide a space so that the cutting load is reduced and the discharge of the cutting chip is smooth.
- the structure of every two cutting inserts is formed differently, and there is a distinction of shape, and opposite cutting of both insert mounting sheet portions
- Figure 1a is a perspective view showing one embodiment of a conventional rotary slot milling cutter
- FIG. 1B is a detailed view of the portion A of FIG. 1A showing an insert mounting sheet part structure
- 1c is a perspective view of a conventional cutting insert
- 1D is a view showing a state in which the cutting insert is inserted into the slot of the workpiece to be machined
- Figure 2a and 2b is a cross-sectional view showing the structure of the conventional insert and the slot processed by the insert of the present invention
- Figure 3 is a perspective view showing the structure of a rotary slot milling cutter equipped with an insert of the present invention
- FIGS. 4a to 4c are views for explaining the structure of the cutting insert according to the invention and the cutting insert is bonded to the insert mounting seat of the milling cutter;
- 5A and 5B are views illustrating a case in which the cutting insert of the present invention is correctly mounted and a case in which the cutting insert of the milling cutter body is correctly mounted.
- Figure 3 is a perspective view showing the structure of a rotary slot milling cutter equipped with an insert of the present invention
- FIGS 4A to 4C are views for explaining the structure of the cutting insert according to the present invention and the state in which the cutting insert is bound to the insert mounting seat of the slot milling cutter.
- 5A and 5B are diagrams respectively illustrating a case where the cutting insert of the present invention is correctly mounted or incorrectly mounted on the insert mounting seat of the milling cutter.
- the cutting insert 50 of the present invention is mounted on the cutting insert mounting seat 130 provided on the main body 110 of the milling cutter 100, and has a substantially rectangular hexahedron shape. It forms a body, and has a structure in which a cutting edge 51 is formed at one corner along the circumference of the body. At this time, the cutting edge 51 is formed as a round processing portion of a radial shape on the cutting insert of any one of the cutting insert located on both sides.
- a groove 54 having a predetermined size is formed on one side of each cutting insert 50, that is, a protruding surface in contact with the object to be removed, and the groove 54 has a cutting insert 50 and a cut to be cut during slotting.
- the cutting insert 50 of the present invention has a structure in which a polygonal insert groove 52 is formed on a mounting surface mounted on the insert mounting seat 130 of the milling cutter 100. Achieve.
- a polygonal sheet protruding on the cutting insert mounting seat 130 of the slot milling cutter 100 is inserted into and coupled to the insert groove 52 corresponding to the insert groove 52.
- a member 150 is formed.
- This structure is such that the cutting inserts on both sides of the milling cutter 100, for example, the right side R and the left side L of the milling cutter 100, are coupled to the insert mounting seat 130, respectively.
- Cutting insert (50 or 50 ') of the milling cutter 100 is prevented from being incorrectly mounted on the insert mounting seat portion 130.
- each of the insert grooves 52 and 52 'formed on the mounting surface in contact with the cutting insert mounting seat 130 of the milling cutter 100 has a polygonal shape. Therefore, by forming the polygonal structure differently, the misalignment is prevented that the cutting insert 50 coupled to one side is mounted to the insert mounting sheet portion 130 of the other side.
- the insert groove 52 formed on one side of the insert 50 of the present invention is because the sheet protruding member 150 of the milling cutter 100 coupled thereto forms a polygon, the difference in the shape of these polygons In this case, erroneous mounting of the cutting insert 50 is prevented.
- the polygonal sheet protruding member 150 formed on the insert mounting seat 130 of the present invention has a low rigidity due to the thin thickness of the cutting insert mounting seat 130 remaining as a problem of the rotary slot milling cutter. It works to solve structural problems that are difficult to mount reliably. That is, since the sheet protruding member 150 formed on the upper surface of the insert mounting sheet 130 has a certain thickness, it is to reinforce the thin thickness of the cutting insert mounting sheet 130 of the bottom.
- the sheet protruding member 150 has a binding through-hole 153 formed at the center of the body 151 having a predetermined thickness, and a spiral 155 is formed on the inner circumferential surface of the through-hole 153.
- FIG. 4B (a) is a view showing the binding surface portion of the cutting insert 50 of the present invention, (b) is a view showing the insert mounting seat portion 130 of the milling cutter as viewed from above, respectively. Drawing.
- FIG. 5A illustrates a case in which the corresponding cutting insert 50 is correctly mounted on the insert mounting seat 130 of the milling cutter.
- the cutting edge 51 of the cutting insert 50 is illustrated in FIG. ) Is fitted in the rotational direction for cutting so that cutting can be performed properly.
