The advantages of milling processing function of CNC EDM small hole machine

The use of CNC EDM small hole machine to develop milling processing is a new type of EDM method. Using the small hole machine electrode tube for 3D or 2D contour machining, like a CNC milling machine, no longer requires the manufacture of complex shaped electrodes. It can smoothly process stainless steel, hardened steel, cemented carbide, high temperature and heat-resistant materials, titanium alloys and other difficult-to-machine materials.



Compared with EDM, this processing method has the advantages of saving a lot of forming electrodes, short production cycle, low processing cost, and high processing flexibility.



Similar to ordinary mechanical milling, EDM milling can be divided into vertical axis, horizontal axis and oblique axis EDM according to the inclined position of the electrode rotation axis. When the electrode axis is placed horizontally or obliquely, the relative feed movement of the electrode and the workpiece can be realized by the three-axis linkage of X, Y, and S of the CNC EDM small hole machine tool, or by the two axes of X, S and the The rotation of the workpiece is linked to achieve. For example, lateral helical grooves, 2D contoured lands or pits can be machined with the groove milling function.
