Overview
About Ruhrzerspanung GmbH & Co. KG
Who we are
We are a family-run company specializing in the production of machine components on CNC-controlled lathes, milling machines and grinding machines. Our contract manufacturing options are precise, flexible and diverse. Based on technical drawings, machine components are produced in a three-shift operation. With our machines and over 30 employees we are able to meet highest quality requirements. Our range of customers includes the gear manufacturing industry, hydraulic, recycling and the construction machinery industry as well as the general mechanical engineering. The production consists of individual parts as well as small and medium-sized batch sizes. Our 19 machines cover a wide variety of machining possibilities. We work with materials either provided by you or offered by us. Competent partners are available for those work-flow procedures which are not covered by us including e.g. heat treatment, gearing and welding work. This enables us to produce complete components and assemblies. Our goal is to completely satisfy you in terms of management, technical advice, flexibility, quality and the adherence to delivery dates. With over 25 years experience in this business, we successfully follow these values.
