ABSTRACT:
A device for straightening the wire of a wire electroerosion machine includes a straightening block that is displaceably arranged on a beam and that can be fixed to the clamping table of a machine tool. The block has a through-opening, and a corner portion of the block is missing. In the vicinity of the side walls of the remainder of the block, an electrically contacting means is provided under each side wall. The longitudinal axes of the contacting means are at right angles to one another and are located in the same horizontal plane. The particular contacting means contains a bolt, which is located in a bore running roughly at right angles to the central bore in the block. At the end of the bolt located in the central bore is eccentrically provided a contact element having a cylindrical surface. The eroding wire can be brought into contact with the surface of the contact elements of the two contacting means. The device makes it possible to adjust the position of the eroding wire with a precision in the range of 2 to 3 thousandths mm.
