Processing product characteristics
Material: Aviation-grade high-temperature alloy GH4169 (nickel-based reinforcement)
Process: Precision drilling and reaming (aperture tolerance ±0.01mm)
Hardness: HRC43 (high-hardness difficult-to-cut material)
Surface requirements: Roughness Ra＜0.5μm (aviation hydraulic parts standard)
Industry pain point analysis
A. Aviation parts processing background
GH4169 alloy is widely used in aviation engine parts due to its high temperature resistance and high strength, but its low thermal conductivity can easily lead to problems such as tool chipping and work hardening. Traditional processes are difficult to meet the dual requirements of efficiency and precision in the modern aviation manufacturing industry.
B. Three major defects of traditional processing
Low efficiency: single hole takes more than 50 minutes (affecting the delivery cycle of aviation parts)
Poor surface quality: vibration marks are prone to appear on the hole wall (causing the risk of hydraulic system seal failure)
High tool wear: the drill bit needs to be replaced every 20 holes (increasing the manufacturing cost of aviation parts)
MID Solutions core technology
Ultrasonic vibration assisted processing system: 20kHz high-frequency vibration reduces cutting force (solves the problem of GH4169 sticking tool)
Composite coating reamer: TiAlN coating tool life increased by 300% (suitable for mass production of aviation parts)
Green cooling solution: micro-lubrication technology (in line with environmental protection standards of aviation manufacturing industry)
Measured performance breakthrough
Efficiency improvement: single hole processing time from 53 minutes → 10 minutes (suitable for urgent aviation orders)
Precision leap: roughness Ra 0.082μm (3 times higher than the standard of aviation engine)
Cost optimization: tool life extended to 80 holes/piece (reducing the cost of aviation parts per piece)
