About Stenzel Feinwerktechnik
Stenzel Feinwerktechnik GmbH, based in Tornesch, Schleswig-Holstein, is a supplier of fine-mechanical components for the laser technology, medical, defense and mechanical engineering sectors. Its 40-strong team manufactures on a state-of-the-art machine park with more than 10 CNC milling machines (3- and 5-axis, including Hedelius, DMG MORI, Makino, robot-assisted production) as well as 9 CNC lathes (DMG MORI, Gildemeister, Emco) with turn-mill technology, C-/Y-axes, counter-spindle and bar-loading systems. The process spectrum also includes wire EDM with precisions down to ±3 µm (Rz 2 µm), assembly of in-house workpieces including purchased parts, wet painting, laser marking as well as deburring and finishing. Materials are aluminium, stainless steel, steel and plastics. Production ranges from single-piece orders and prototype series to large and small series. Surface finishing and heat treatment are carried out with long-standing partners, including anodizing, hard anodizing, electropolishing, zinc plating, hardening and nitriding. With the construction of the new production facility, which was ready for occupancy in August 2009, the foundations were laid for economical manufacturing of complex tasks with the highest precision. Quality is ensured through a certified DIN-EN-ISO-9001 quality inspection on Zeiss and TESA measuring machines.
