Background

The slow-speed wire, also called low-speed wire, is a kind of numerically controlled machine tool which uses continuously moving fine metal wire (called electrode wire, generally copper wire) as electrode to make pulse spark discharge to workpiece, and generates high temperature above 6000 deg.C, and then removes metal and cuts it into workpiece. The slow wire-moving machining principle is that a seam gap exists between a wire electrode and a workpiece, and metal is removed by continuous discharge, the conventional electric spark perforating machine utilizes a thin metal copper pipe (also called as a wire electrode) which continuously rotates and vertically moves as an electrode to carry out pulse spark discharge on the workpiece to remove the metal, because the diameter of the metal copper pipe for pulse discharge is very small, the length of a complete wire electrode is generally 400mm and 300mm, and when the initial use loss of the wire electrode moves downwards, the middle part of a clamp holder and a guide device is very easy to bend and deform.

When a small hole is machined, the electrode tube needs to rotate stably, the middle part of the electrode tube deforms to cause some abnormalities in a machining area, the bottom of the machining area is contacted with a workpiece, namely, the part contacted with the workpiece generates circular runout, and the position precision and the aperture precision of the small hole are influenced.
