Solutions for cost effective and high-quality machining of aerospace landing gear/main fitting
Typical landing gear components are main/nose/centre 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.
Tooling solutions for aerospace in landing gear/main fitting
CoroMill® MS20 – pocketing
- M-M20 geometry gives higher security in tougher applications
- In case of sensitive / vibration prone applications and / or applications requiring a sharper cutting edge, the E-L50 geometry can be used
- The higher edge line toughness of these geometries allows the inserts to be used with higher productivity (high cutting data) in stable operations
- Robust steel shank design ensures better stability and less deflection. The improved tool body material can withstand chip rubbing better
Profile milling
CoroMill® 216 is a robust ball nose end mill perfect for semi-finish profile milling. The cutter has inserts with two edges for effective and general contouring and copy milling.
Internal turning using Silent Tools
Silent Tools is the trademark for a family of tool adaptors for turning, milling and boring. The tool adaptors are designed to minimize vibrations through a damper inside the tool.
A standard Silent Tool boring bar programme 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 of an extraordinarily high standard.
The serration lock coupling is now equipped with a full range of cutting heads with high pressure coolant capability.
CoroTurn® SL70 - specifically designed for profiling and pocketing
Specifically designed for profiling and pocketing for complex aerospace components, the CoroTurn® SL70 modular system reduces the need for special tools and excessive inventory. Adaptors offer improved accessibility for axial and internal machining so that cutting blades or heads can be used in any configuration.

Rough milling around a boss
For productive secure machining use CoroMill® 300 with a roll in programme combined with round inserts to reduce notch wear and allow high feed rates.
CoroMill® 690 - developed specifically for high-productivity 2D profile milling of titanium components
Inserts are securely fastened by iLock technology. By equipping every insert pocket with threaded coolant holes with nozzles for high pressure coolant delivery, you can apply maximum coolant where required.
