Introduction: CNC Milling Cutters – Precision Tools for Modern Manufacturing
CNC milling cutters are essential for precision manufacturing, shaping materials with accuracy in industries like aerospace and electronics. This guide covers what they are, how they work, and how to choose the best type
1. What is a CNC Milling Cutter? Definition & How It Works
A CNC milling cutter is a rotating tool that removes material from workpieces via high-speed rotation. It creates flat surfaces, slots, and complex 3D shapes. Key parts:
- 정강이: Connects to the machine spindle.
- Cutting Teeth: Directly remove material.
2. Types of CNC Milling Cutters & Their Uses
Choose based on material and geometry:
- 설계: Flat bottom, sharp edges.
- Uses: Surface milling, slots, engraving.
- Subtypes:
2-플루트: Best for aluminum (fast chip removal).
4-플루트: Smoother finishes on steel.
Ball Nose End Mill
- 설계: Rounded tip for 3D shapes.
- Uses: Mold making, aerospace parts.
Corner Radius End Mill
- 설계: Rounded edges reduce stress.
- Uses: High-strength slotting.
T-슬롯 커터
- Specialized: Machines T-slots in fixtures.
팁의 경우:
- Carbide Tools: Ideal for titanium/stainless steel.
- HSS Tools: Cost-effective for aluminum/plastics.
3. Top Applications of CNC Milling Cutters
- 항공우주: Lightweight alloys (티탄, 알류미늄)
- 자동차: Engine blocks, custom parts.
- Electronics: Smartphone frames, laptop casings.
- Mold Making: Injection mold cavities.
4. How to Choose the Best CNC Milling Cutter
Step 1: Match Tool Material
- Stainless steel → Coated carbide.
- Cast iron → TiCN-coated.
Step 2: Optimize Geometry
- Helix Angle: 30°–45° for aluminum; 10°–20° for steel.
- Core Thickness: Thicker for heavy roughing.
Step 3: Balance Cost & Quality
- Premium Brands (Sandvik, Kennametal): High-volume durability.
- Local Brands: Budget-friendly for small batches.
결론
CNC milling cutters ensure precision and cost-efficiency in manufacturing. By selecting the right type and optimizing parameters, businesses reduce downtime and boost productivity.
