High-speed EDM drilling machines make very small holes in very hard materials

The APos series of high-speed EDM drilling machines from Heun GmbH offers high performance in metal processing for mould and tool making, machine and workholding-tool construction and other applications. Small-hole drilling via electrical discharge machining is employed in situations where removing material by mechanical machining methods is not efficient or even possible.

A topologically optimised maintenance door for aircraft with dimensions of approx. 775 x 477 x 238 mm. The combination of 3D printing and precision casting made it possible to reduce the weight by 30% compared to conventional production methods. Only 3D printing with polymethyl methacrylate (PMMA) makes it possible to print a large door in a single piece and then precision-cast it. (Voxeljet)

How classic foundries remain competitive against 3D printing

Aircraft manufacturers, automotive OEMs and designers: When rapid production of small batches of complex parts is required, more and more companies are turning to 3D metal printing. However, there are ways for traditional foundries to make friends with the competing manufacturing method.
