Abstract
A machined article 100 includes a first member 101 including an inner peripheral portion 101a formed by a hole, and a second member including an outer peripheral portion 102a fitted into the inner peripheral portion 101a of the first member 101. At least either an inner peripheral recess 101b to be formed in part of the inner peripheral portion 101a of the first member 101 or an outer peripheral recess 102b to be formed in part of the outer peripheral portion 102a of the second member 102 is formed. A slit 103 penetrating from a front to a back is formed at a position to which the inner peripheral recess 101b or the outer peripheral recess 102b corresponds, between the first member 101 and the second member 102.
Claims13
A machined article comprising:
- a first member including an inner peripheral portion formed by a hole;
- and
- a second member including an outer peripheral portion fitted into the inner peripheral portion of the first member, wherein
- at least either an inner peripheral recess is formed in part of the inner peripheral portion of the first member or an outer peripheral recess is formed in part of the outer peripheral portion of the second member is formed,
- a slit penetrating from a top surface to a bottom surface of the machined article is formed at a position to which the inner peripheral recess or the outer peripheral recess corresponds, between the first member and the second member, the slit forming a gap between the first member and the second member;
- the inner peripheral portion of the first member being continuous entirely from the top surface to the bottom surface of the machined article, and the second member being fitted into the inner peripheral portion of the first member such that the inner peripheral portion of the first member and the outer peripheral portion of the second member are in direct contact with each other where the slit is not formed, wherein the machine article is configured for jetting fluid or powder.

A pressing method comprising the steps of:
- providing a machined article comprising:
- a first member including an inner peripheral portion formed by a hole;
- and
- a second member including an outer peripheral portion fitted into the inner peripheral portion of the first member, wherein
- at least either an inner peripheral recess is formed in part of the inner peripheral portion of the first member or an outer peripheral recess is formed in part of the outer peripheral portion of the second member is formed,
- a slit penetrating from a top surface to a bottom surface of the machined article is formed at a position to which the inner peripheral recess or the outer peripheral recess corresponds, between the first member and the second member, the slit forming a gap between the first member and the second member;
- the inner peripheral portion of the first member being continuous entirely from the top surface to the bottom surface of the machined article, and the second member being fitted into the inner peripheral portion of the first member such that the inner peripheral portion of the first member and the outer peripheral portion of the second member are in direct contact with each other where the slit is not formed, wherein the machine article is configured for jetting fluid or powder, the method further comprising the step of:
- pressing part of the first member out of material to form the inner peripheral portion;
- pressing part of the inner peripheral portion to form the inner peripheral recess;
- pressing the second member out of the material so that the outer peripheral portion is formed, and holding the second member;
- and pressing the second member to fit the outer peripheral portion of the second member into the inner peripheral portion of the first member so that the inner peripheral recess forms the slit.
