Precision Revolution: SDFTOOLS 0.2mm Micro Tools Conquer Nickel Alloy Machining

Precision——25xD Micro End Mills & Drills Redefine Manufacturing Limits

When a leading European aerospace manufacturer faced 100% tool failure rate on Inconel 718, Sundefu Precision answered the call with groundbreaking innovation Revolution: Sundefu’s 0.2mm Micro Tools Conquer Nickel Alloy Machining

The Impossible Challenge

• 0.2mm diameter (1/3 human hair)
• 5mm flute length (25xD ratio)
• Workpiece: Inconel 718 (45-50 HRC)
• Competitor tools: Max 37 seconds tool life

Sundefu’s Technological Breakthroughs

1. Nano-Engineered Coating System

• ALD-deposited TiAlN/AlCrN multilayer
• 1200℃ thermal barrier protection
• 3X wear resistance improvement

2. Biomimetic Cutting Edge Design

• Shark skin-inspired flute geometry
• 42% cutting force reduction
• 5μm edge preparation technology

3. Smart Machining Ecosystem

• Adaptive spindle speed control (30k-80k rpm)
• Real-time feed compensation (±0.5μm)
• Dedicated CAM post-processor

Performance Benchmarking

Technical Assurance

• Zeiss Xradia 810 Ultra nano-CT inspection
• Keyence VHX-7000 digital microscope
• 100% 36-step quality certification

“Next goal: 0.1mm tools for aerospace composites,” states Dr. Zhang, CTO.
