Fabrication de pièces

Dans la fabrication de pièces, l'usinage des composants est stationnaire, c'est-à-dire que les composants sont usinés dans une machine avec une ou plusieurs fixations d'outils. Les pièces cubiques de petite et moyenne taille peuvent être usinées sur un centre d'usinage, tandis que les composants de grande taille nécessitent des machines spéciales à portique.

Usinage du titane par enlèvement de copeaux

Usinage du titane par enlèvement de copeaux

En raison des exigences élevées dans l'aéronautique et l'aérospatiale concernant la solidité et la résistance à la corrosion par rapport aux contraintes de poids spécifiques, le titane et les alliages de titane sont des matériaux de choix prédestinés. En conséquence, les domaines d'application sont très variés et s'étendent des petits composants structurels usinés par procédé mécanique aux éléments porteurs du fuselage ou des aubes dans les propulseurs.

Usinage de l'aluminium

Usinage de l'aluminium

La recherche constante de l'allégement implique l'utilisation de matériaux particulièrement légers et stables. L'aluminium présente une résistance spécifique élevée combinée à un poids propre assez faible et s'avère donc un matériau de construction idéal. Comparés à l'acier, les composants en aluminium pèsent environ moitié moins pour une résistance égale, mais présentent un volume plus important.

Plastics and CFRP machining

Plastics and CFRP machining

Fibre composite materials are very strong and rigid relative to their light weight. The properties of the materials can be modified as required, by making use of various matrix materials and types of fibres. This allows the optimal fulfilment of the requirements that are made of the part. The parts are manufactured using a near net shape technique. Machining tasks include, among other things, the subsequent machining of the outer contour and the manufacturing of functional surfaces.

Solutions for final assembly

Even today, handheld machines are still used in the final assembly of aircraft, due to their size. For example, in final assembly lines (FAL), rivet holes are made in the outer skin of the aircraft’s fuselage. The tools are equipped with special guiding elements.

Robot systems

Robot systems

Robots with end-effectors for drilling and riveting mounted on shuttles are moved from assembly position to assembly position along the aircraft fuselage and position themselves automatically. MAPAL has defined various tool features especially for the aerospace industry that can be adapted optimally to the material and the boundary conditions, depending on the machining situation.

• High process reliability
• Optimum tool design for every application
• Many years of experience guarantee the best machining results

Drill feed units

Drill feed units

In contrast to handheld machines, drill feed units allow the tool to be guided mechanically. An additional guidance is required from a total length of 120 mm or more. The use of drill bushes is recommended. Our tools convince through:

• Minimal burr formation and improved centring
• Optimal bore quality and a long tool life
• Low emissions when machining

Hand drills

Hand drills

Handheld machines offer a high degree of flexibility but lack the qualities required for stable tool guidance. As a result, additional stabilisers are needed to produce a constant diameter. MAPAL has developed a range of high-performance tools specifically for machining with handheld machines and drill feed units.

• Drilling from solid

  Tools for drilling from solid in multilayer composite materials (stacks) made out of CFRP, aluminium, high-alloy steels or titanium with a hand drill.
   

• Boring and reaming

  Boring and reaming of through bores tools with special cutting leads and guiding elements for the reliable production of precise bores with high surface quality and accurate concentricity.

• Countersinking

  Producing precise, circular countersinks and spot faces on bores that have already been pre-drilled.
