Safety machining solutions for the Aerospace Industry
In an increasingly competitive environment, the aerospace industry is engaged in a race to reduce weight and production costs. Hence, the materials of choice combine low weight and mechanical resistance, enabling them to meet the reliability challenges faced during their use.
The boom of these materials has, thanks to its compability, placed Titanium – TA6V, Ti5553, Ti10.2.3 – in the front seat and increases its usage.
Its excellent relation between mechanical resistance and density makes it a given choice for the design of engines, landing gear or frame structures.
For engine components that are subjected to strong mechanical stress at high temperatures, Inconel remains the most widely used material.
Safety, innovative standard and engineered solutions
Being a partner with the aerospace industry since many years, Safety possesses the know-how and experience to be a specialist acknowledged for its solutions for titanium and inconel machining. Safety supports its customers defining the machining strategy to be able to meet the reliability challenges, inherent to the extremely expensive work pieces.
When manufacturing needs required a specific responses our engineering department performs and exact diagnosis, develops and implements a tailored solution, perfectly adapted to the toughest demands.
Solutions for frame and landing gear
Frame components are often reinforced by stiffeners containing pockets with varying depth more or less open.
Our milling cutters PENTA High-Feed or ORBI-SAF for roughing or semi-finishing, and our new cutters AEROFINISH or POLYMILL for finishing are perfectly adapted for these particular applications.
When contouring at large depths of cut, our now milling cutter AEROLONG provides the optimal solution for roughing or semi-finishing.
The specific configuration of landing gears comprises joints and connection of different cylindrical shapes, which generates progressive radii.
These zones are generally accessible using toroic and ball nose milling cutters. Our toroic milling cutters RD-SAF, TORO-SAF and ARAF with carbide bodies and our ball-nose cutters SR-SAF and SM-SAF provide the best productivity for roughing and semi-finishing operations.
Solutions for engines.
The manufacturing of engines, primarily consisting of rotating components, requires a number of turning operations. The operations vary between simple external turning and the machining of difficult to access grooves, that require an engineered solution.
The choice of geometry is vital, requiring an optimal compromise between wear resistance and cutting forces. By achieving this optimum, residual stresses are minimized and the surface integrity of vital components is assured.
Our geometries SR, 1L, F5, M2 & M4 are design for optimal performance. Combined with our grades 9605, KX2 & KX20, they allow for significant productivity gains in the material mostly used in aero engines.
For example, the 1L geometry, between extremely positive, is perfectly adapted for the finishing of titanium. The grade KX20 is optimized to avoid the phenomenon of built up edge and hence increases the tool life of the insert.
The grade 9605 using Microform technology is especially developed for the aerospace industry, optimized for semi-finishing and finishing applications of difficult-to-machine materials, for the excellent dimensional tolerances, surface quality, productivity and security.
