The performance of modern EDM equipment is extremely high: high cutting speeds, highly efficient automation, interlinking and storage of very long and recurring machining cycles. And thanks to electronic monitoring and fully automated correction of the EDM process, no supervision is required.
Compared to conventional EDM's, the new NOVICK® EDM range can reduce average energy consumption by up to 60%. The newly developed power supply with very latest technology supplies efficiently discharge energy and high motor power with a minimum of losses and heating. The energy used in the manufacturing of the actual component parts is also dramatically reduced as the new machine design requires remarkably fewer mechanical parts and uses high efficient energy saving electrical components.
Four different processes
In the case of die-sinking EDM, the required shape is formed in the workpiece with a three-dimensional electrode. By superimposed movements in the main axes X, Y, Z, C, varied shapes, indentations and cavities are created, such as cannot be achieved by any other machining system.
In the case of wire-cut EDM, the metal is cut with a special metal wire electrode. The wire travels along a pre-programmed path. By differing movements of the upper and lower wire guides, angled or conical surfaces can be produced to the highest accuracy and with the finest surface finish.
EDM drilling is a form of Die-sinking using rotating electrode.
Electro Discharge Grinding
This process is hybrid of EDM and grinding. Unlike the grinding process, EDG is not an abrasive related process. This process uses metallic grinding wheel without abrasive particles. The cutting edge geometries and final dimensions of cutting tools are typically produced on CNC tool and cutter grinders. Tools with PCD cutting edges, however, pose a challenge. Grinding PCD pits the hardest known substance (diamond) against an equally hard grinding wheel. The resulting virtual standoff consumes excessive time and wheels. Electrical Discharge Grinding is an efficient and accurate way to remove PCD when manufacturing or regrinding PCD tools.
