Home » Aerospace Tooling

With technological and material advancements the aerospace industry is experiencing huge changes. The size of new craft is doubling, which is stark contrast to the halving of development time. This pressure to make prototypes into finished products is a challenge for manufacturers and the process they adopt and the new wave of composite materials mean most are in uncharted territory and tooling and application can quite literally make or break the job at hand. As aerospace has evolved into commercial space travel, innovation has forced the need to reduce weight and material innovation has lead to cutting tool innovation as composites by their very nature are difficult to machine.

ALCA TOOLS LTD are proud to supply combined power of Walter, Walter Titex and Walter Prototyp and together we are able to deliver far more than tools. When you have a application and need tooling to produce that component, we are right with you, from concept to finished product, but it doesn’t stop there. We then revisit time and time again in order to see if the process can be improved upon to increase output and reduce cycle times. We are a single source for complete machining processes. From engineering support to tool management, and from titanium, high temperature alloys to composite materials, no one else stands beside you to achieve your high standards as efficiently and cost effectively as possible like ALCA TOOLS LTD. Contact us today and let us help you achieve more.

00 Engine

The aerospace industry is competitive on an international scale with manufacturers and service providers. The pressure to ensure aircraft are lighter and safer is paramount to the future of the industry. The customer experience is also a high priority, ensuring safety and environment is to the highest safety standards.

This presents a challenge for machining too, since materials which are difficult to machine, such as those used in the manufacture of jet engines, require special metal cutting tools and reliable, integrated processes

We have the right tools for machining titanium, composites or Ni/Co alloys. Our industry specialists possess a vast knowledge and many years of experience in the machining of demanding materials in the aerospace industry. With our extensive knowledge and experience, we develop tailored machining processes for you.


00 Fuselage

The fuselage is the main assembly of an aircraft. Quite literally almost everything is attached to the fuselage: wings, tailplane, landing gear, cockpit, cabin, tanks.

The main requirements for the fuselage are, firstly, low weight and secondly, the largest possible stiffening formers in cross section and longerons in longitudinal section play a significant role in this stability.

Lightweight construction materials such as aluminium, aluminium/lithium alloys and composite materials such as CFRP and glass-fibre reinforced aluminium are chosen today for manufacturing this structure. Using our high-performance tools, including PCD tools, we develop component-specific machining solutions for the production of these components.


00 Pylons

The main task of the aerofoils is to provide the aircraft with the necessary lift. Individual components machined here include the pylon bracket, made from titanium, the wing box, made from composite materials, and the reinforcing ribs, made of aluminium.

In a structural component such as the wing box, our tools are used to machine the holes, the pocket contour and the pocket bottoms, etc. It is particularly important here to provide a high surface finish quality and the highest degree of stability.

We also develop a machining solution for our customers which is tailored to the machining of the complex, thin-walled aerofoil ribs made of aluminium and uses high-speed PCD mills.

Landing Gear

00 Landing Gear

One of the major components of any aircraft is the landing gear. It absorbs the enormous forces on take-off and especially during landing. Besides the engine, the components used here are subject to the strictest demands in terms of reliability and functionality under extreme conditions. The main components of the landing gear are the landing gear support beams, master cylinders, hydraulic components, connecting elements, axles and wheels. While some aircraft models use aluminum, the most commonly used materials are alloyed steels and titanium.

The main types of machining used are 3- and 5-axis milling, boring and fine boring. The size of these components impos limitations on the machine environment. Large portal milling machines and mill-turn centres must be used. In addition, the users rely on multi-spindle machines with very high torque. Our industry specialists develop machining processes tailored according to component and material, using our high-tech tools for turning, boring and milling.
