Custom Undercutting End Mill – Lollipop End Mill – Standard
Undercut end mills, often called lollipop cutters because of their spherical cutting form, are tooling solutions engineered for bottom U-slot and side cavity machining. Furthermore, their ball-shaped cutting portion is also excellent for intricate 3D surfacing and fine finishing, especially in high-precision profiling applications for molds, complex contours, and medical instruments.
Custom Undercutting End Mill Reference
Detailed Parameter Suggestions:
- Number of Flutes: 3-4 flutes (recommended for deep cavity machining to reduce vibration), 5-6 flutes (recommended for fine finishing of curved surfaces to improve surface finish).
- Helix Angle: Large helix angle (35°~45°) for soft materials, small helix angle (25°~30°) for hard materials.
Application Scenarios:
- Mold Making: Parting lines of injection molds, fine finishing of complex curved surfaces in die-casting molds.
- Aerospace: 3D surface machining of titanium alloy engine blades.
- Medical Devices: Complex contouring of artificial joints.
- Automotive Components: Machining of internal complex-shaped cavities in gearbox housings.
