Abstract: An electrical discharge machine including a lower support part (2) provided to a tilt shaft (4) rotatable and extending horizontally and an upper support part (3) provided to a forward/backward shaft (5) extending parallel to the tilt shaft (4) from a support column (42) provided vertically to the tilt shaft (4) and movable forward and backward in the extending direction. The lower support part (2) includes a lower guide roller (21) that rotates in a tilting plane in which the tilt shaft (4), the support column (42), and the forward/backward shaft (5) lie, the upper support part (5) includes an upper guide roller (31) that rotates in the tilting plane in which the tilt shaft (4), the support column (42), and the forward/backward shaft (5) lie, and a wire electrode (1) is suspended around the upper guide roller (31) and the lower guide roller (21).

Abstract: To provide an electrical discharge machine in which a wire electrode can be angled in the left-right direction (u direction) and the front-back direction (v direction), an electrical discharge machine according to an embodiment of the present invention includes a lower support part (2) provided to a tilt shaft (4) rotatable and extending horizontally and an upper support part (3) provided to a forward/backward shaft (5) extending parallel to the tilt shaft (4) from a support column (42) provided vertically to the tilt shaft (4) and movable forward and backward in the extending direction, in which the lower support part (2) includes a lower guide roller (21) that rotates in a tilting plane in which the tilt shaft (4), the support column (42), and the forward/backward shaft (5) lie, the upper support part (5) includes an upper guide roller (31) that rotates in the tilting plane in which the tilt shaft (4), the support column (42), and the forward/backward shaft (5) lie, and a wire electrode (1) is suspended aro
