หัวกัดที่มีความแม่นยํา,เครื่องมือตัดสําหรับเครื่องจักรกลซีเอ็นซีทุกวัสดุ
As the “industrial teeth” of modern manufacturing, milling cutters enable high-efficiency material removal through high-speed, multi-edge cutting. Compared to single-point tools, their alternating cutting mechanism delivers three key advantages:
- Enhanced Heat Dissipation: Rotating teeth provide 30% longer cooling time per edge, extending tool life by 40%
- Improved Stability: Multiple edges reduce vibration, achieving surface finishes up to Ra 0.4 μm
- Unmatched Productivity: Enables higher material removal rates (เช่น, face milling at 20 cm³/min)
Example: Aerospace turbine blade machining with ø16 mm 4-flute ball nose cutters (R0.8 mm) achieves:
- Feed per tooth: 0.08 mm
- Cutting speed: 80 m/min
- 4 mm axial depth of cut
- Surface roughness: Ra 0.4 μm
หัวกัด Types and Applications
1. End Mills
Structure: Cylindrical body with peripheral/end cutting edges
โปรแกรม ประยุกต์:
- Precision mold cavities (เช่น, smartphone components)
- 3D contouring (requires 5-axis CNC)
- Thin-wall aluminum machining
2. Face Mills
Key Specs:
- เส้นผ่านศูนย์กลาง: 80-315 mm
- Teeth: Coarse (4-6), Medium (8-10), Fine (12-14)
Case Study: - Engine blocks: 300 min tool life with negative inserts
3. Slot Drills
Design:
- Body width = slot size (เช่น, 10 mm tool for 10 mm slot)
- Chip gullet depth: 60% of diameter
Industrial Use: - Hydraulic valve T-slots (±0.05 mm tolerance)
4. Form Cutters
Technical Requirements:
- Profile accuracy ≤0.02 mm
- High-precision holders (≤0.01 mm runout)
