Machining of metals

Graphite Machining – Precision & Clean Manufacturing for Technical Applications At EROSIÓN DE PRECISIÓN EROPREC, S.L. (ERO-PREC), we offer high-precision graphite machining services for industries that demand accuracy, cleanliness, and high-performance materials. Graphite is an ideal material for applications requiring electrical conductivity, thermal resistance, and dimensional stability — such as EDM, foundry molds, aerospace, metallurgy, and electronics. Thanks to our specialized CNC equipment and decades of expertise, we produce complex graphite parts with tight tolerances and superior finish, whether for individual prototypes or small production batches. Why Graphite? Graphite is lightweight, electrically and thermally conductive, and stable at high temperatures. Its machinability and resistance to wear make it ideal for both industrial and high-tech applications. At EROPREC, we work with a wide range of technical graphite grades to meet your exact functional and dimensional requirements. Benefits of Graphite Machining with EROPREC High dimensional precision on fragile or intricate components Clean dry machining with dust containment and controlled environments Tailored parts produced to drawing or 3D model CNC machining of all industrial graphite types: isostatic, extruded, molded, impregnated In-house expertise in EDM graphite electrode design and manufacturing Common Applications Graphite electrodes for sinker EDM Non-ferrous casting molds (aluminum, copper, brass) High-temperature thermal components Brushes, electrical contacts, furnace parts Insulating rings, nozzles, guides, and custom parts Graphite Grades We Machine Isostatic graphite (high-density, fine-grain – ideal for precision EDM) Molded and extruded graphite (durable and cost-efficient) Synthetic graphite (low porosity, high purity) Impregnated graphite (for chemically or thermally demanding applications)
