Description
Product Overview
This carbide ball nose end mill is designed for cavity machining,
curved-surface milling, three-dimensional contouring and mold profile
finishing of mold, die and tool steels with workpiece hardness up to HRC60.
It combines an ultra-fine carbide substrate, HIPIMS TiAlSiN coating,
precision-ground full-radius geometry and unequal cutting geometry
to reduce vibration and support consistent surface quality during
demanding mold steel machining.
Recommended Machining Applications
The full-radius ball nose profile supports continuous cutting contact
during curved-surface, cavity and three-dimensional mold machining.
Cavity Machining
Suitable for mold cavities, recessed areas and internal
profiles requiring smooth tool movement.
Curved-Surface Milling
Designed for rounded, free-form and transition surfaces
with continuously changing contact angles.
3D Contouring
Supports complex three-dimensional CNC toolpaths,
mold contours and sculptured surfaces.
Mold Profile Finishing
Suitable for semi-finishing and finishing mold profiles,
transition areas and detailed surface features.
Ball Nose Geometry and Cutting Performance
The carbide substrate, high-temperature coating, anti-vibration
geometry and precision radius control are combined to support
stable mold steel machining.
Ultra-Fine Carbide Substrate
Ultra-fine carbide with a grain size below 0.6 μm and
12% cobalt content provides a balance of cutting-edge
strength, toughness and wear resistance.
HIPIMS TiAlSiN Coating
The TiAlSiN coating uses HIPIMS deposition and an enhanced
alloying design to improve high-temperature performance,
reduce friction and support resistance to impact and crack
propagation at temperatures up to approximately 1200°C.
Full-Radius Ball Nose Profile
The precision-ground full-radius cutting profile supports
continuous tool contact during cavity, contour and
curved-surface machining.
Ball Radius Accuracy Within 3 μm
Walter HELICHECK PLUS profile inspection helps control
ball radius accuracy within 3 μm for consistent mold
profiles and repeatable surface geometry.
88° / 92° Unequal End Teeth
The two-degree unequal end-tooth division helps disrupt
repeated cutting forces, reducing vibration and improving
machining stability.
35° / 37° Unequal Helix
Unequal peripheral helix angles help reduce harmonic
vibration during contouring, cavity machining and
mold profile finishing.
0° to −5° Rake Geometry
The controlled rake-angle range reinforces the cutting edge
and supports stable machining of difficult mold and tool
steels with hardness levels up to HRC60.
Fluid-Blasting Edge Preparation
Fluid blasting helps remove microscopic burrs and stabilize
the cutting edge, contributing to smoother cutting and
improved workpiece surface quality.
Automated Edge Polishing
Automated rubber-bonded diamond polishing helps maintain
consistent edge preparation, with the preparation value
controlled within ±0.003 mm.
Walter Five-Axis Grinding
Walter five-axis precision grinding supports ball-profile
accuracy, cutting-edge consistency and repeatable geometry
for smoother mold machining.
