Ball end mill and cutting insert

Автор: Yasuhito Fujii, Yasuyuki Endoh

Принадлежит: OSG Corp

Large diameter edges formed in arc shapes having curvature radii larger than a ball radius are provided. This allows improving surface roughness of a machined surface by cutting of a planar surface with the respective large diameter edges compared with cutting of a planar surface with a ball end cutting edge formed in an arc shape having a single curvature radius. Further, since the respective large diameter edges are formed in the arc shape, compared with cutting of a curved surface with linear cutting edges, surface roughness of a machined surface can be improved by cutting a curved surface with the respective large diameter edges. Accordingly, a pick feed during the cutting of the planar surface and the curved surface with the respective large diameter edges can be increased, and therefore machining efficiency in the cutting of both of the planar surface and the curved surface can be improved.

The invention relates to a reset mechanism of the key duplication device which comprises a reset apparatus, a spindle and a body, wherein the spindle is inserted into the body and is rotatably connected to the body. Between workspace and a loading area, the body is repeatedly moveable along the spindle. The reset mechanism comprises an elastic member connected with the body. Elastic forces of the elastic member always act on the body and move the body toward the workspace. After the body is rotated to the loading area against the elastic forces of the elastic member, when a withdrawal force exceeds the elastic forces, the body automatically returns to the workspace under the influence of the elastic forces. The fewer and easier operating steps the more efficient work of the reset mechanism is, and the mechanism more conforms to the ergonomics design. 1.
