Abstract

PURPOSE:To prevent unsymmetrical wear of a finish end mill and to improve finish accuracy by cutting the plane of an end plate along a specified finish locus after cutting it along a specified pre-cutting locus, when machining a scroll with bodies protruding on the end plate. CONSTITUTION:A scroll type fluid machine is equipped with a pair of scroll S with spiral bodies 2 protruding on its end plate 1. In machining the scroll S, in this case, the plane 1a of the end plate 1 and the side face of the spiral body 2 located outside the terminal end 2b of the spiral body 2 are machined first with a precutting end mill E1 along a pre-cutting locus L' which is located outside a finish locus L on the outer edge of the plane facing the other spiral body 2. Next, the plane 1a of the end plate 1 and the side face of the spiral body 2 are machined with a finish end mill E2 along finish locus L. By following this procedure, unsymmetrical wear of the finish end mill E2 can be prevented and the finish accuracy of the spiral body 2 can be improved.

When b) is cut by end milling from the end of the spiral of the spiral body (A) to a semicircular position along the virtual spiral locus of the spiral body, the peripheral surface of the tip of the end mill is excessively worn, There was a problem that the finishing accuracy of the spiral body deteriorated.

なる問題があった。That is, when cutting the plane (b) of the end plate (B) located outward from the spiral end edge (C) of the spiral body (A),
Continuing with the cutting of the inner surface of the spiral body (A) and the end plate plane that is continuous with the inner surface, the plane (b) is cut with the same end mill, and the spiral end edge of the spiral body (A) is cut with the same end mill. The spiral body (
Without A), the flat surface of the head plate would have to be cut shallowly, resulting in excessive wear on the circumferential surface of the tip of the end mill. Therefore, if a spiral body is repeatedly cut with the same end mill, a step will be formed on the side surface of the spiral body, resulting in poor finishing accuracy.In addition, in order to keep this machining accuracy constant, it is necessary to cut the spiral body repeatedly. There was a problem that the replacement life was shortened.

This is to make it possible to do so.

The plane of 1) has a pre-cutting locus (L') located outward from the finishing locus (L) of the outer edge of the plane facing the other spiral body.
Since pre-cutting is performed along the pre-cutting end mill, the circumferential surface of the tip part of the pre-cutting end mill will be worn excessively and the pre-cutting surface of the spiral body will deteriorate, but this is not a problem since it is a pre-cutting surface. In addition, during finishing milling, the tip edge of the end mill comes into contact with the flat surface of the end plate and cuts the flat surface, so it is possible to improve the finishing accuracy of the spiral body (2), and eliminate uneven wear of the finishing end mill. This makes it possible to extend the replacement life of the end mill.

After cutting with a pre-cutting end mill (E,) along the pre-cutting locus of the spiral body (2), the inner surface of the spiral body (2) and the corresponding parts are cut from the spiral start edge to the spiral end edge. The plane (1a) of the end plate (1) that is continuous with the inner surface is cut by the pre-cutting end mill (E) along the pre-cutting locus of the spiral body as shown in FIGS. 1(a) and 2(a). Next, the outer surface of the spiral body (2) and the plane (1a) of the end plate (1) that is continuous with the outer surface are cut from the spiral end edge of the spiral body (2) toward the spiral start edge. is cut with a finishing end mill (E2) along the finishing locus (L) of the spiral body, and then the inner surface of the spiral body (2) is continuous with the inner surface from the spiral start edge to the spiral end edge.

ないようにするのである。First, the plane (1a) of the end plate (1) located outward from the spiral terminal edge (2b) of the spiral body (2) in the fixed scroll (S,) is shown in FIG. and second
As shown in figure (b), the yA roll (2) of the revolving scroll (S2)
) Pre-cutting is performed with the pre-cutting end mill along a pre-cutting locus (L') located radially outward from the finishing locus (L) of the outer edge of the plane opposite to the pre-cutting end mill. That is, Fig. 1 (
As shown in FIG. 2(A) and FIG. An end mill (E1) is displaced radially outward from the finishing locus (L) of the inner surface of the spiral body (2), and the end plate is positioned outward from the terminal edge (2b) of the spiral body. The plane (la) of (1) is cut along the pre-cutting locus (L'), and during finishing cutting, the finishing end mill (E
The circumferential surface of 2) is prevented from coming into contact with the outer edge of the opposing plane of the mirror plate (1).

することになる。Therefore, after cutting the inner surface of the spiral body (2), the pre-cutting end mill (E,) cuts the inner surface of the spiral body (2), and then uses the tip end peripheral surface of the head plate (
Since the outer edges of the opposing planes in 1) are pre-milled, the peripheral surface of the distal end thereof is worn more than the peripheral surface of the proximal end, resulting in uneven wear, as in the conventional case.

仕上げ用エンドミルの交換寿命も長くできるのである。As a result, when cutting the spiral body of another scroll, a step is formed on the pre-cut surface of this scroll, but this is not a problem because it is a pre-milled surface. After the finishing end mill (E2) cuts the inner surface of the spiral body (2), only the tip edge contacts the end plate flat surface (1a), and the tip wears out, resulting in a shortened length. Therefore, when finishing the spiral body in another scroll, the finishing accuracy of this spiral body can be improved, and
The replacement life of finishing end mills can also be extended.

On the plane of the end plate (1) located outward from the end of the spiral, there is a spiral body (2) in the revolving scroll (S2).
The end edge of the spiral is located, and this orbiting scroll (s2)
Since the compressible fluid is compressed between the inner peripheral surface of the spiral body of the fixed scroll (S1) and the outer peripheral surface of the spiral body of the fixed scroll (S1), the plane (1a) is the tip surface of the spiral body of the revolving scroll (S2). It is only necessary to finish the opposing plane with high precision, and the outer edge of the opposing plane does not need to be finished with high precision.
