As an example, the business is very satisfied with the portal machining centre from Droop+Rein, which W&H brought into operation in 2008 to enhance two portal milling machines from another manufacturer. “On these machines, we primarily produce large frame parts for our whole range of machines,” says Richter. “These components play an important role for us, as they make a significant contribution to the high quality of our printing machines, processing machines and film winders.”

Just as important a role is played by the core components for blown-film extrusion lines, which are partially made from chrome-nickel heat-treated steel forged especially for W&H, or from grey iron and cast aluminium turned parts. Every part is unique in batch size 1. In order to ensure productive machining, W&H relies on complete machining and quick tool handling. Due to growing demand, the Westphalians decided on a Dörries CONTUMAT VCE, a new vertical turning lathe from the Starrag Group.

At the request of W&H, the 4.5-metrehigh turning lathe also has a basement beneath it that is over 5 metres deep. The demands on the machine are very high indeed, since W&H predominantly uses the CONTUMAT to manufacture com- ponents for blow-moulding machines with an accuracy of 20 μm. The components can weigh up to 2 tons and have a maximum rotation diameter of 1,800 mm.

The driving force for this comes from two high-performance 40 kW electric motors (torque: 38,300 Nm). They are located in the basement, along with the water treatment equipment, which is accessible for servicing and maintenance. Richter: “When designing the basement, we received excellent expert advice from the Starrag Group.” Environmental concerns are playing an increasingly important role in Lengerich, next to efficiency, performance, reliability and safety. For this reason, in the case of new investments, W&H ensures that the machine room is fully encapsulated with suction and filtration of emulsion fumes. This attitude goes down very well with employees, whose high levels of motivation are particularly important to the Westphalian firm. A comment from machine operator Andreas Gräler: “I am very impressed by the complete enclosure, as it makes my work on the machine quiet and safe.”

That is an indication of just how the machines are designed to match customers’ requirements. Richter: “In fact, machine tools from the Starrag Group can be configured precisely in accordance with customer requirements.” Proof that the new marketing message “Engineering precisely what you value” has been a reality for some time.
