Bending technology, fixture construction and service from a single source
IBT Lerinc GmbH, based in Rohrdorf/Thansau in Upper Bavaria, specializes in bending technology, fixture construction and machine tool service. The company designs and manufactures mandrel bending, compression bending and profile bending tools, bending mandrels, wiper dies and axial tools for chipless tube end machining. Production takes place in-house on 3- to 5-axis CNC milling machines and turn-mill centers, complemented by CAD/CAM workstations that allow work directly from 3D models even without existing production drawings. Various steels are machined (stock from block sizes 40x40 to 250x250), as well as non-ferrous metals and plastics, complemented by surface treatments such as blackening, case hardening, vacuum hardening, gas nitriding, plasma nitrocarburizing and anodizing. Production covers lot sizes from 1 to 50 pieces and is aimed at industrial manufacturing, machine tool construction and tube processing. In addition, the company offers machine tool service, retrofit, automation as well as instruction and training.
