Powerful Machining for the Highest Quality Standards

CNC machining of critical components for the aerospace industry is among the most demanding processes in the entire sector, requiring full compliance with the highest industry and safety standards. In addition to precision, one of the most decisive factors in producing these workpieces is achieving the greatest possible performance. Correspondingly, machining high-strength materials presents a significant challenge.

Aubert & Duval is a well-known and leading reference in the aerospace sector, serving as the sole supplier and manufacturer of wheel carriers for Airbus as well as balance arms and wheel carriers for Boeing. As a French producer of critical components made from high-performance steel and titanium – the most widely used metals in aerospace manufacturing – the company holds a key position within the industry. In the field of aerospace technology, the force and performance demands placed on machines for processing large workpieces are immense. Optimal vibration damping when machining large and heavy components on boring mills is crucial for process stability, surface quality, and tool life. To machine these high-strength alloy components made of steel and titanium – as well as parts made from Inconel – with absolute precision, the customer chose to invest in a TYPE PCR 162 II boring machine. “In particular, workpieces made from the demanding nickel-chromium superalloy Inconel – which is known for its high strength and exceptional resistance to corrosion and heat, and is therefore widely used in the aerospace industry – are extremely difficult to machine with a standard machine,” explains Michel Gras, Project and Sales Manager for the Benelux countries and France. “This is why the customer was immediately convinced by our boring mill, which stands out for its impressive machine stability and spindle performance, as well as its enormous spindle torque – enabling significantly shorter machining times.”

The PCR 162 II is equipped with a Siemens machine control system, state-of-the-art workpiece and tool measuring systems, and a pick-up station for accommodating the units, including a holder for the special tools. “The machine enables precise and flexible machining of complex contours and free-form surfaces. It is also suitable for various milling processes, which makes it even more flexible,” explains Michel Gras.

In addition, the boring mill is equipped with enhanced operator and workspace protection, allowing the machine operator to access the tool magazine and change tools on-the-fly. “Screens have also been installed both in the operator’s cabin and at other strategic locations to monitor the machining process in real time and provide an effective solution for improving process and work safety as well as quality assurance,” says Michel Gras. A compact coolant system, the hydraulic rotary and sliding table with a zero-point clamping system for faster workpiece changes, and the resulting significantly reduced machine downtimes complete the machine’s functionality and scope of delivery perfectly.
“Our boring machine will play a key role at Aubert & Duval in machining the main components at the Les Ancizes site,” concludes Michel Gras.
