About ACunity
ACunity GmbH, based in Aachen, offers complete solutions for the production chain in the fields of laser deposition welding, laser welding and additive laser manufacturing – including equipment and hardware development as well as process development. The core technology is Extreme High-speed Laser Material Deposition (EHLA), with which the surfaces of metallic components can be protected against wear and corrosion, repaired or additively manufactured in an environmentally friendly and material-saving manner. The portfolio includes the machine systems EHLA flexi (robot-guided, virtually unrestricted working space), EHLA pro (external and internal coating) and EHLA max (components longer than 10 m) as well as in-house powder feeders with highly precise micro powder feeding. For laser microprocessing, ACunity uses Helical Drilling Optics for ultrashort-pulse laser helical drilling and cutting with holes below 20 µm and aspect ratios up to 1:30, implemented on four high-end machine tools of the ACMicro series. Customers come from mechanical and plant engineering as well as virtually all industries and sectors.
