1.2343 Material EDM Machining Plastic Mold Parts with 48-52 HRC Hardness and +/-0.01mm Tolerance for Custom OEM Applications
EDM (Electrical Discharge Machining) operates on the principle of material removal through high-temperature sparks generated between the electrode and workpiece. This process is particularly suitable for machining high-hardness conductive materials, with CNC EDM machines representing the most advanced form of this technology.
EDM machining is primarily used for creating complex shapes and delicate workpieces including punches, dies, embossing dies, fixing plates, unloading plates, forming knives, stencils, metal electrodes, micro-holes, narrow slits, and arbitrary curves. The technology offers significant advantages including minimal machining allowance, high precision, short production cycles, and low manufacturing costs, making it widely adopted in industrial applications.

EDM mold processing typically employs coarse, medium, and fine grading. Roughing achieves high power with minimal loss, while medium and precision machining may involve slightly higher electrode loss. However, given the small machining allowances in these stages, electrode loss remains negligible and can be compensated through size control without affecting precision requirements.
Successful EDM processing depends on effective carbon residue generation and removal. Processing speed may be sacrificed to manage carbon residue through techniques like high voltage and large pause pulse waves during medium and finishing stages. Complex surface geometries may require additional measures to ensure proper chip removal and processing conditions.
Longer discharge pulse durations help minimize electrode loss. Roughing typically uses long pulse waves with high current, resulting in minimal electrode loss. In contrast, finishing requires smaller currents and shorter pulse times, which increases electrode loss and reduces processing speed.
