Landing gear - main landing gear cushioning pillar outer cylinder
Typical landing gear components include main landing gear/front landing gear/intermediate landing gear cushioning struts, piston rods/sliders, axle beams, struts, and the like. Its main material is high alloy steel, such as 300M. However, the current trend is to use titanium alloys such as Ti-5553. The main challenges in producing the main landing gear cushioning pillar outer cylinder are deep hole drilling, bore turning and profile milling.
Deep hole machining
The T-MAX 424.10 drill has an adjustable diameter and is equipped with interchangeable inserts and inserts to ensure small diameter tolerances and high surface quality. Standard drill diameters range from 65 - 130mm, diameters from 130 - 183.99mm are Tailor Made, and 184.00 - 327.99 are available upon request.
