AM-LOCK  –  Zero point clamping system for 3D metal engraving

pL ADDITIVE is a division of pL LEHMANN. With over 50 years' experience in machining production and as a manufacturer of CNC rotary tables for over 40 years, we are closely familiar with the demands placed on industrial production processes. The need for a zero-point clamping system was inspired by the fact that many workpieces made by LPBF technology need to be post-machined for mating surfaces, threads, surfaces or other precision contours. This synergy will allow the user not only to produce the 3D-printed workpieces, but also to post-machine and finish it in an efficient, precise and reliably manner. Here we focus mainly on the following post-processing methods:


  • Measuring, inspection
  • X-ray
  • Heat treatment up to 650 °C
  • All machining production technologies such as turning, milling, drilling, grinding, eroding, water jetting
  • Hirtizing (Hirtenberger, AT), an electrolytic surface treatment method and support structure removal


Together with a well-known manufacturer, the development for a suitable zero point positioning clamping system AM-LOCK was started. It soon became clear that the installation space itself (construction shaft, construction platform) presents unresolved challenges for the manufacturers and the users. Also in this specific environment, pL ADDITIVE has acquired expertise in order to be able to advise you in the best possible way.
