| Zusammenfassung: | To provide a radius end mill that can achieve a glossy processed surface whose cut trace is unnoticeable after cutting processing so as to reduce the man-hours for polishing processing.SOLUTION: The radius end mill comprises a bottom blade 1, a corner R blade 2 consecutively formed at an outer periphery side of the bottom blade 1, and an outer peripheral blade 3 consecutively formed at the corner R blade 2, where a corner R slidably-contact surface 5 that comes into slide contact with a cut surface cut by the corner R blade 2 is consecutively arranged along the corner R blade 2.SELECTED DRAWING: Figure 1
【課題】切削加工後に切削痕の目立たない、光沢のある加工面を得られ、研磨加工の工数を低減できるラジアスエンドミルを提供することを目的とする。【解決手段】底刃１と、この底刃１の外周側に連設形成されるコーナＲ刃２と、このコーナＲ刃２に連設形成される外周刃３とを備え、前記コーナＲ刃２に沿って該コーナＲ刃２が切削した切削面に摺接するコーナＲ摺接面５が連設されているラジアスエンドミル。【選択図】図１ |
