With our precise drilling EDM technology, we can realise the finest drill holes in metal parts, even in the most demanding materials. Our machines enable us to maintain tight tolerances and produce even complex bores in 5-axis with the highest precision.
Drill EDM is a special application of die-sinking EDM (also known as spark erosion drilling or start hole drilling) and is used in particular when high feed rates are required. During the production process, the electrode rotates, which leads to uniform burn-off and rapid removal of material from the workpiece.

With the usual care, CFK produces precise bores with a diameter of 0.35 to 7.5 mm and a height of 800 mm on 3- and 5-axis machines. One special feature is our 5-axis drilling-eroding machines, which are used, for example, to machine complex components made of materials that are difficult to machine, including those from the gas turbine industry.
Drill erosion, or drill EDM, is a high-precision manufacturing technique that is used in various demanding industrial sectors. This technology enables us to realize the finest holes and complex structures in hard or difficult-to-machine materials that are difficult or impossible to achieve with conventional machining processes. Drill erosion is particularly useful for the production of starting holes for wire erosion processes. These starting holes allow us to insert the wire for wire EDM into the workpiece without affecting the material structure. This technique is crucial for the production of tools and molds, especially in the automotive and aerospace industries, where precision and material integrity are of paramount importance. We also use drill EDM for the production of through and blind holes in hard metals and alloys, which are often used in medical technology and mechanical engineering. This technique is ideal for the production of small, complex parts where traditional drilling methods reach their limits. Another important application of EDM is the machining of materials that need to withstand extreme conditions, such as those found in power generation and research and development. Here, drill EDM enables us to manufacture high-precision components that have to function under extreme temperatures and pressures.
