About us
Günter Sievers Maschinenbau GmbH, based in Hemmingen near Hanover, has been manufacturing timing belt pulleys, gears, V-belt and poly-V-belt pulleys as well as clamping connectors and clamping plates to individual customer specifications since 1971. The range of services extends from single-piece and small-series production to larger series production. In addition to machining on CNC machining centers – turning, milling and gearing including finishing operations such as thread cutting, grooving and deburring – the company also offers laser-cut parts, laser beam welding and additive manufacturing (3D printing). Production is carried out in steel, plastic, brass and aluminium. Quality assurance includes, among other things, 3D measurement of gears. Customers come from the mechanical engineering, drive technology and conveying technology sectors. In addition, the company carries out design work according to customer specifications.
