Claims

[Claims for Utility Model Registration] (1) A shank with a connecting part to the main shaft of the machine at one end is rotatably supported within a unit case, and an intermediate casing is mounted on a surface perpendicular to the shank provided in the unit case. The intermediate casing has an inclined surface inclined at 45 degrees with respect to the shank axis, and the support casing has an axis inclined at 45 degrees with respect to the shank axis on this inclined surface. The mounting shaft of the cutting tool, which is rotatably connected to the center and connected to the other end of the shank within the support casing via a drive conversion mechanism, is set at 45 degrees relative to the rotation axis of the support casing.
The unit case is rotatably supported around a shaft tilted at an angle of 20 degrees, and the unit case is provided with a case fixing pin that can be locked on the end face around the main shaft, and the unit case and the intermediate casing, and the intermediate casing and the support casing are connected to each other. In the cutting mounting unit, which is provided with a fixing means for fixing them at a predetermined rotational position between them, a first scale is provided at the connecting part between the unit case and the intermediate casing to indicate the amount of rotation of the intermediate casing with respect to the unit case. , a second scale at the joint between the intermediate casing and the support casing that indicates the amount of angle required to rotate the support casing relative to the intermediate casing when tilting the cutting tool at an arbitrary angle relative to the shank axis; and a third scale indicating the amount of rotation of the intermediate housing relative to the unit case necessary for indexing the cutting tool in a plane including the shank axis before rotating the support casing. A cutting tool mounting unit featuring: (2) The angle from the reference point of each scale in the second scale and the third scale is t ₁ and t ₂ , respectively. If α is the angle the cutting tool makes with respect to the shank axis, and θ is the rotation angle of the intermediate housing when the cutting tool is indexed within the plane at that angle α, then the angles t ₁ and t ₂ are cos The cutting tool mounting unit according to claim 1, wherein the cutting tool mounting unit is set according to the relationship: (t ₂ )=1-4tan ² θ+2.
