About Knebel Metalltechnik
Knebel Metalltechnik GmbH in Frankfurt am Main manufactures sheet metal parts, CNC turned and milled parts, EDM-machined workpieces, tools, plants and fixtures as a supplier and contract manufacturer. In the field of CNC sheet metal working, fiber laser cutting systems (sheet format up to 3000 x 1500 mm), a CNC punching machine, press brakes with bending lengths up to 3100 mm as well as round and tube bending machines are used. On 3- and 5-axis machining centers, even difficult-to-machine materials such as titanium, copper, glass composite alloys and stainless alloys are machined; machining centers with a maximum workpiece weight of 14 t are available. In addition, the company offers wire, sinker and small-hole EDM (also with graphite), spot welding, TIG welding, laser welding, stud welding, deburring and vibratory finishing processes as well as toolmaking (punching, embossing and progressive dies) and plant engineering including electrical, hydraulic and pneumatic assembly. An in-house joinery performs CNC woodworking in combination with metal, glass and plastic for model making, trade fair construction and interior fittings. Customers include airport and baggage handling technology, airline maintenance tooling, the woodworking industry and trade fair construction. Deliveries are made to the European and American regions.
