thread production machines- other Germany

... strict quality controls that run like a common thread throughout the entire manufacturing process. State-of-the-art manufacturing technology, highly precise CNC-controlled machining centers turn, drill, mill, and grind the workpieces into shape. Heavily stressed parts such as drill heads or pistons undergo an elaborate hardening process. Other workpieces are corrosion-protected through chrome plating or galvanization. With the final inspection, everything possible has been done to ensure a powerful and durable product.
