Singapore’s Aerospace Helps
Friendly Skies Fly Safe
Singapore’s aerospace sector is one of the island-nation’s shining lights that has helped propel the tiny Southeast Asian nation onto the international stage as an important contributor to the world economy.
As of 2012, the Singaporean aerospace industry generated S$8.7 billion and employs over 19,900 workers. By doing so, it has attracted international aerospace players by facilitating the rigorous machining standards on difficult-to cut-materials as well as composites.
As a result, both the Safran/GE’s CFM Leap X turbine as well as Rolls-Royce’s Trent 1000 turbine engines are manufactured in Singapore.
The metals, alloys and composites used in aerospace components are some of the toughest to shape and demand high tolerance capabilities ranging from Inconel, titanium/alloy, aluminum/alloy to composites such as Carbon Fiber Reinforced Plastic (CFRP).

TT Tooling Systems, TaeguTec’s Singapore distributor, provides the best know-how and cutting tool technology that covers the gamut of aerospace components from landing gears and casings to turbines.
The primary objective in aerospace machining is to achieve the best material removal rate under the best velocity and speed while minimizing production cycle times.
MillRush is a high-speed milling line that specializes in roughing to finishing operations on all aerospace components.
Both the ChaseMill and ChaseAlu cutters focus on “roughing” as well as medium operations.
TaeguTec’s line of Poly-Crystalline Diamond (PCD) tipped cutters and diamond coated end mills come in both standard and tailor made items that solve the delamination issue faced in CFRP machining.
Tailor made turning PCD inserts with high-pressure coolant, in one client’s application, was employed against Ti-6Al-4V. The results were impressive; 150 m/min speed, a feed rate between 0.2-0.3 mm/rev with excellent chip evacuation while minimizing the associated heat during machining.
Another example, TaeguTec’s DrillRush line handled both roughing and finishing operations with speeds between 60-80 m/min, averaging 0.15-0.2 mm/rev using sharp cutting edges indexable and non-indexable drills with less honing.
Using the ChaseMold’s round type RYMX MLL and MM inserts designed with a higher rake angle than other round insert types, manufacturers can achieve very favorable metal removal rates and avoid built-up-edges in 5-axis machines for extended tool life.
TaeguTec’s line of holders and inserts, available in a wide range of PVD grades, covers the entire spectrum of applications for machining all difficult-to-cut materials.
