- the present invention relates to a cutting tool, an insert holder, and an insert, and more particularly to a cutting tool, an insert holder, and an insert that can improve stability and cutting accuracy during cutting.
- Patent Document 1 a cutting tool in which a plurality of inserts each having a blade portion for cutting a workpiece are detachably held on an insert holder to facilitate replacement of the blade portion.
- Patent Document 1 a long insert is held by an insert holder so as to be sandwiched between both ends by an annular member.
- the contact surface between the both ends of the insert and the annular member is formed perpendicularly or parallel to the axis of the insert holder. Therefore, there is a risk that the distance from the insert holder axis to the plurality of inserts may vary due to the clearance for fitting the insert into the insert holder, or the distance from the insert holder axis to the insert may change during cutting. There is. As a result, the load from the workpiece may concentrate on some of the inserts, or the inserts may vibrate during cutting, which may reduce the stability and cutting accuracy during cutting.
- the present invention has been made to solve the above-described problems, and an object thereof is to provide a cutting tool, an insert holder, and an insert that can improve the stability and cutting accuracy during cutting.
- the insert holder having both the first end and the second end as both ends includes a body and a lid attached to the second end side of the body.

- projection part is formed in the 2nd holding
- the first holding surface of the first holding unit is in surface contact with the first overhanging surface
- the second holding surface of the second holding unit is in surface contact with the second overhanging surface. Since the insert is pressed toward the body due to the inclination of these surfaces, variation in the distance from the axial center to the blade portions of the plurality of inserts can be suppressed, and the insert can be hardly separated from the body during cutting. As a result, load concentration on some inserts can be suppressed, and vibrations of the inserts can be suppressed. Therefore, there is an effect that stability and cutting accuracy at the time of cutting with a cutting tool can be improved.

Since the inner diameter of the second cylindrical portion is larger than the inner diameter of the first cylindrical portion, the rotational driving device can be inserted into the second cylindrical portion, and the rotational driving device can be brought into contact with the end surface of the first cylindrical portion.
- the bolt inserted into the through hole and the first tube portion is fastened to the rotation drive device in a state where the rotation drive device is in contact with the end surface of the first tube portion, so that the head between the bolt head and the rotation drive device is secured.
- the lid portion and the body are sandwiched between the lid portion and the lid portion is fixed to the body.
- the insert since the insert is formed up to the second end of the insert holder while being held by the insert holder, the workpiece can be cut by the insert even at the second end of the insert holder. Further, since the second overhanging portion projects into the groove portion from the lid portion whose outer diameter is set to be smaller than the outer diameter of the body, the groove portion is located outside the second overhanging portion and on the outside of the lid portion. The groove opens to the second end side of the body. Thereby, the insert formed to the 2nd end of the cutting tool in the state hold
- the second overhanging portion is continuously formed over the circumferential direction of the insert holder.

- the maximum distance from the groove bottom 14a to the first inner surface 17a may be set larger than the minimum distance from the groove bottom 14a to the second inner surface 18a.
- the space between the groove bottom 14a and the first inner surface 17a and the space between the groove bottom 14a and the second inner surface 18a are vertically symmetrical and have the same shape. Therefore, the second holding portion 34 can be sandwiched between the groove bottom 14a and the first inner surface 17a, and the first holding portion 33 can be sandwiched between the groove bottom 14a and the second inner surface 18a.
- the direction in which the insert 30 is held by the insert holder 10 can be changed according to the degree of wear of the blade portion 31, the life of the insert 30 can be improved.
