向上を図ることができないという問題があった。However, in the conventional shaped tool 200 described above, it is possible to shorten the tact time of the cutting process as compared with a tool provided with a single blade, but the blade is not. Since 200A to F cut different inner diameters or end faces at the same spindle rotation speed, a difference occurs in the cutting speed of each blade part 200A to F, and the degree of wear of the blade parts is different, so that re-polishing is performed. The intervals are different, and further, it is necessary to remove the shaping tool 200 from the lathe for this re-polishing, and since the blade portions 200A to 200F are integrally formed, re-polishing requires a great deal of skill and labor, There is a problem that the time required for maintenance increases and the operating rate of the lathe decreases, so that productivity cannot be improved.

The inner circumference of the work can be machined in one cutting process by the clamp bites respectively arranged on the second mounting surface, and the cutting reaction force received by the bite holder main body during cutting is the axis line of the spindle. The first and second mounting surfaces extending along the axis are arranged so as to be point-symmetric with respect to the main axis C in a plane including the same, and substantially the same number of clamp bits are arranged on each mounting surface. As a result, the cutting reaction force applied to each mounting surface is almost equal, the bending applied to the tool holder body is reduced, chattering and vibration of the tool holder body during cutting can be prevented, and the machining accuracy can be improved. Since the cutting tool is removably attached to the first and second mounting surfaces, the cutting speed of each clamp bit differs depending on the inner peripheral shape of the work, and the tool life varies, but the blade part wears. It is possible to perform the maintenance easily and in a short time by directing a new cutting edge to the workpiece to change the orientation of the exchange or clamping bytes clamping bytes depending on the state.

上させることができる。As described above, according to the first aspect of the present invention, the inner circumference of the work can be processed in one cutting step, and the cutting reaction force received during cutting is the plane including the axis of the main shaft. At the inner,
Since the first and second mounting surfaces are arranged point-symmetrically with respect to the main axis and the mounting tools are provided with approximately the same number of clamp bits, the cutting reaction force applied to each mounting surface is substantially equal. The bending force and rotation moment applied to the bite holder body can be reduced to prevent chattering and vibration of the bite holder body during cutting and improve machining accuracy. Each clamp bit has a first and second mounting surface. Since it is detachably attached to the tool, the cutting speed of each clamp bit varies depending on the inner peripheral shape of the work and the tool life varies, but the clamp bit must be replaced or replaced depending on the wear of the blade. Maintenance work can be performed by changing the direction of the clamp bite and directing the new cutting edge toward the work. This maintenance work is performed by removing the bite holder body from the lathe as in the conventional method. The process can be performed easily and quickly without the need for the step of cutting, does not require skill and a lot of time as in the conventional example, and improves the operation rate of the lathe by reducing the labor and time required for maintenance. This makes it possible to improve productivity. Furthermore, if this bite holder body is applied to an NC lathe, one operator can handle multiple N
The C lathe can be easily managed, and the productivity can be further improved.
