Claims

[Scope of utility model registration request]

(1) In a wire-cut electric discharge machine that cuts a workpiece using a continuously supplied metal wire as an electrode, the plane of the processing table that fixes the workpiece is the X-Y plane, and the two axes perpendicular to this are A processing table that can arbitrarily position the workpiece within the X-Y axis plane,
a first wire guide that supports a wire electrode at a point on the Z-axis below or above the processing table; and a second wire guide that supports the wire electrode above or below the processing table; A wire-cut electric discharge machine characterized in that one of the first wire guide and the second wire guide is provided with a mechanism for simultaneously imparting rotational drive and reciprocating motion. +21 Wire electrode that can move the second wire guide, which rotates around the z-axis out of the first and second wire guides, to any angle around the z-axis and at the same time by any amount from the center of rotation. A rotary drive mechanism that rotates around a point different from the rotation center, and a second rotary drive mechanism on the rotary drive mechanism.
Equipped with a reciprocating mechanism that supports the wire guide,
Furthermore, there is a device for arbitrarily setting the rotation angle around two axes and the inclination angle with the Z axis of the wire electrode stretched between the first and second wire guides, and a processing table where the plane stretched between the Z axis and the wire electrode is set. A mechanism is provided to drive and control the rotation angle of the second wire guide around the Z axis and the amount of movement due to the reciprocating motion that determines the inclination angle in synchronization with the processing table so that the second wire guide is in the normal direction to the movement direction of the second wire guide. Scope of claim for utility model registration No. 1
Wire-cut electrical discharge machine as described in Section 1.
