About Koblenzer Werkzeugbau GmbH
For more than 18 years, Koblenzer Werkzeugbau GmbH has been a partner of the metalworking industry in machining technology. The company manufactures and machines precision machine components and assemblies for machines, systems, tools and fixture making. Production is carried out predominantly on CNC-controlled machines and includes CNC milling and CNC turning, surface and cylindrical grinding, wire and die-sinking EDM as well as slotting. In addition, the company offers tool making (including punching, cutting and piercing tools, dies, punches), fixture and gauge making, assembly, overhauls of machine components and optimization of assembly modules. The service portfolio is complemented by additional services such as heat treatment (nitriding, case hardening, induction and vacuum hardening), surface treatment (anodizing, chromating, phosphating, burnishing, hard material coatings such as TiN, TiCN, CrN), hardfacing, deep-hole drilling and sheet metal work in C45 and stainless steel sheet. Materials machined include steel up to 60 HRC (hard machining), titanium, stainless steel as well as engineering plastics such as PEEK, POM, PTFE, PVC and HGW hard glass fabric. The company is located in the Koblenz Rhine port industrial area with direct access to the A3, A48 and A61 motorways.
