Solutions for cost-effective and high-quality machining of aerospace landing gears/main fittings

Solutions for cost-effective and high-quality machining of aerospace landing gears/main fittings

Typical landing-gear components are main/nose/center fitting, piston/slider, truck/bogey beam, drag brace and links. The main materials are high-alloy steels such as 300M. But there is a trend that these will be produced in titanium alloys such as Ti-5553. The main challenges in the main fitting are deep hole drilling, internal turning and profile milling.

Internal turning using Silent Tools™

Silent Tools™ is the trademark for a family of tool adapters for turning, milling and boring. The tool adapters are designed to minimize vibrations through a damper inside the tool.

A standard Silent Tool™ boring bar program up to 250 mm (9.843 in) diameter and 14 x dia to length capability is available. This range of tools can produce component features that meet extraordinarily high standards.

The serration lock coupling (SL) is now equipped with a full range of cutting heads with high-pressure coolant (HPC) capability.

CoroTurn® SL70 – Specifically designed for profiling and pocketing

Specifically designed for profiling and pocketing complex aerospace components, the CoroTurn® SL70 modular system reduces the need for special tools and excessive inventory. Adapters offer improved accessibility for axial and internal machining so that cutting blades or heads can be used in any configuration.
