Abstract
There is provided a tool positioning device and a machining element whose structures are simple and which can reduce a running cost. In addition to a hole that engages with a shank of an end mill, a channel is provided so that it penetrates through the device such that one end thereof communicates with an upper face of the device and the other end communicates with a lower end of the device. In this case, it is more effective to provide a concave portion that is opened to the upper face and communicates with the hole. The same effect may be obtained by making a cylindrical hole for example instead of the channel.
Claims6
A hollow and cylindrical tool positioning device for positioning an edge of a tool, comprising:
- a hole that penetrates through a center part of said device in an axial direction to attach said tool;
- an upper face which is a plane orthogonal to said axial direction;
- a lower face which is a plane orthogonal to said axial direction;
- an outside face that connects an outer edge of said upper face with an outer edge of said lower face;
- and
- a hollow portion in said axial direction that communicates with said upper and lower faces.
