In the field of aviation manufacturing, carbon fiber composite materials (CFRP) have become the core material of aircraft structural parts due to their high strength and lightweight characteristics. However, problems such as delamination, residual hair and rapid tool wear during its processing have long restricted production efficiency and part reliability.
Traditional processing dilemma
CFRP is very prone to material layer separation during drilling, resulting in substandard hole wall surface quality; the length of layered fiber hair generated during milling often exceeds 0.8mm, and the surface roughness Ra value is as high as 1.211μm. Traditional carbide tools show obvious wear after processing 30 holes, forcing companies to frequently stop and change tools, and production costs have risen by more than 20%.
MID Solutions: Ultrasonic Precision Machining System
To address the pain points of CFRP machining, MID Solutions has innovatively developed a multi-purpose ultrasonic graphite machining system:
Ultrasonic vibration cutting technology: Reduce cutting resistance and inhibit material delamination through 20kHz high-frequency vibration
Integral PCD micro-blade milling cutter: Adopts nano-level cutting edge design, and the life of a single tool exceeds 800 holes
Constant temperature cooling module: Real-time control of machining temperature within 60°C to avoid resin carbonization
Measured data confirms technological breakthroughs
In a landing gear cover processing project of an aviation company, MID solutions achieved:
The length of the hole hair was reduced from 0.8mm to 0.05mm (a decrease of 94%)
The surface roughness Ra value was optimized from 1.211μm to 0.493μm (a decrease of 60%)
The single-piece processing cycle was shortened by 40%, and the yield rate was increased to 99.6%
