Description

上記の課題を解決するため、この発明においては、内径加工用切れ刃を有する切削インサートを備えた刃先交換式内径加工用切削工具を次の通りに構成した。
即ち、前記切削インサートを工具本体の外周に工具回転方向に均等ピッチで複数個配置し、工具の回転中心から各切削インサートの内径加工用切れ刃までの距離を全て等しくした。さらに、前記複数個の切削インサートは、内径以外の領域を内径加工と同時進行で加工する切れ刃を備えさせ、前記内径以外の領域を加工する切れ刃は、穴の内径面と段差面との交差部に設けるぬすみ部を加工するぬすみ部加工用切れ刃にした。 In order to solve the above-mentioned problems, in the present invention, a cutting edge-exchangeable inner diameter machining cutting tool including a cutting insert having an inner diameter machining edge is configured as follows.
That is, a plurality of the cutting inserts are arranged on the outer periphery of the tool main body at an equal pitch in the tool rotation direction, and all the distances from the rotation center of the tool to the cutting edge for machining the inner diameter of each cutting insert are made equal. Further, the plurality of cutting inserts are provided with a cutting edge for machining a region other than the inner diameter at the same time as the inner diameter machining, and the cutting edge for machining the region other than the inner diameter is formed between the inner diameter surface of the hole and the step surface. It was set as the cutting edge for machining the thinning part which processes the thinning part provided in an intersection part.

この内径加工用切削工具は、複数個の切削インサートを全て同一形状にすることができる。 The inside diameter machining cutting tools can all a plurality of cutting insert-like identical shape.

前記内径以外の領域を加工する切れ刃として、例えば、穴の段差面を加工する切れ刃をさらに設けることもできる。 And a cutting edge for machining a region other than the inner diameter, for example, it may be further provided cutting edge for machining a stepped surface of the hole.
