Description
Product Overview
This carbide ball nose end mill is designed for curved-surface machining,
cavity milling, three-dimensional contouring and mold profile finishing
of carbon steel, mild steel, low-alloy steel and cast iron up to HRC55.
Also commonly called a ball end mill, it combines an ultra-fine carbide
substrate, AlTiN nano-composite coating and precision-ground full-radius
geometry for stable CNC machining and consistent contour accuracy.
Recommended Machining Applications
The full-radius ball nose profile supports continuous tool contact
during curved and three-dimensional machining operations.
Curved-Surface Machining
Suitable for machining curved, rounded and free-form surfaces
requiring continuous cutting contact.
Cavity Milling
Designed for cavity bottoms, internal contours and recessed
areas in steel workpieces.
3D Contouring
Supports three-dimensional profiling and complex CNC toolpaths
with changing surface angles.
Mold Profile Finishing
Suitable for semi-finishing and finishing mold profiles,
transition surfaces and complex contours.
Ball Nose Geometry and Cutting Performance
Carbide material, coating, cutting geometry and radius control are
combined to support stable cutting and consistent curved-surface machining.
Ultra-Fine Carbide Substrate
Made from ultra-fine carbide with a grain size below 0.8 μm
and 10% cobalt content, providing a balance of cutting-edge
strength, toughness and wear resistance.
AlTiN Nano-Composite Coating
The high-aluminum AlTiN coating offers red hardness,
oxidation resistance and wear resistance at operating
temperatures up to approximately 1100°C.
Full-Radius Ball Nose Profile
The full-radius cutting profile supports smooth contact during
curved-surface, cavity and three-dimensional contour machining.
Radius Accuracy Within 3 μm
Precision grinding and profile inspection help control the ball
nose radius accuracy within 3 μm for consistent contour machining.
6° Positive Rake Angle
The positive rake geometry helps reduce cutting resistance
and supports smoother cutting in carbon steel and general steel.
35° Helix Design
The 35° helix supports stable chip evacuation and continuous
cutting during contouring and cavity machining.
Dual-Margin Peripheral Edge
The dual-margin peripheral design improves tool guidance and
cutting stability during CNC contour milling operations.
Controlled Edge Preparation
Fluid blasting and automated rubber-diamond polishing help
remove microscopic burrs and control edge preparation
within ±0.003 mm.
