Description
Product Overview
This carbide ball nose end mill is designed for cavity machining,
curved-surface milling, inclined surfaces, three-dimensional
contouring and controlled semi-finishing of stainless steel components.
It combines an ultra-fine carbide substrate, 12% cobalt content,
Balzers AP AlCrN coating, 52%/70% dual-core geometry, an 8°
positive rake angle, a 45° helix and 88°/92° unequal cutting
geometry to improve chip evacuation, vibration resistance and
surface-machining stability.
Recommended Machining Applications
The full-radius ball nose profile supports continuous cutting
contact during stainless steel cavity, curved-surface and
three-dimensional profile machining.
Cavity Machining
Suitable for recessed areas, internal profiles and
stainless steel cavities with continuously changing
cutter engagement.
Curved-Surface Milling
Designed for free-form surfaces, rounded profiles
and curved stainless steel components.
Inclined-Surface Machining
Supports stable machining of sloped surfaces and
transition features where the cutting contact position
changes continuously.
3D Contour Finishing
Suitable for controlled semi-finishing and finishing
of three-dimensional profiles and detailed surface features.
Designed for Stainless Steel Surface Machining
Stainless steel can create ductile chips, concentrated cutting
heat, built-up edge and local work hardening. The ball nose
geometry is designed to maintain stable cutting during changing
contact conditions.
Chip and Heat Control
- 52% front core provides additional flute space
- 45° helix supports smoother chip movement
- 8° positive rake reduces cutting resistance
- Improved chip evacuation helps remove cutting heat
- Reduced risk of chip recutting in cavity machining
- Suitable for stable semi-finishing operations
Surface and Cutting Stability
- 70% secondary core improves cutter rigidity
- Unequal geometry helps suppress repeated vibration
- Precision ball profile supports consistent contours
- AlCrN coating helps reduce heat-related wear
- Controlled edge preparation improves consistency
- Low runout and rigid toolholding are recommended
Ball Nose Geometry and Cutting Performance
The carbide substrate, coating, dual-core geometry, precision
ball profile and controlled edge preparation work together
to support stable stainless steel contour machining.
Ultra-Fine Carbide Substrate
Ultra-fine carbide with a grain size below 0.6 μm
supports cutting-edge strength, wear resistance
and consistent ball nose geometry.
12% Cobalt Content
A 12% cobalt content provides a balance of substrate
toughness, cutting-edge strength and impact resistance
during changing cutting contact conditions.
Balzers AP AlCrN Coating
The AP AlCrN coating provides high hardness, heat
resistance and oxidation resistance at operating
temperatures up to approximately 1200°C.
52% / 70% Dual-Core Design
The front core section is approximately 52% to provide
additional flute space, while the secondary section
increases to approximately 70% for improved rigidity.
Full-Radius Ball Nose Profile
The full-radius cutting profile provides continuous
tool contact during cavity, curved-surface, inclined-surface
and three-dimensional contour machining.
8° Positive Rake Angle
The positive rake geometry supports cleaner cutting
and helps reduce rubbing, cutting resistance, built-up
edge and local work hardening.
45° Helix Geometry
The 45° helix supports smooth engagement, controlled
chip flow and stable cutting during curved-surface
and cavity machining.
88° / 92° Unequal Cutting Geometry
The unequal cutting division helps interrupt repeated
cutting forces, suppress vibration and improve stability
during contour and surface machining.
Ball Radius Accuracy Within 3 μm
Precision grinding and profile inspection help control
the ball radius within 3 μm for consistent cavities,
curved surfaces and three-dimensional contours.
Fluid-Blasting Edge Preparation
Fluid blasting helps remove microscopic burrs and
stabilize the cutting edge, supporting smoother cutting
and improved workpiece surface quality.
Automated Edge Polishing
Automated rubber-bonded diamond polishing helps maintain
consistent preparation across the cutting edges, with
the preparation value controlled within ±0.003 mm.
Walter Five-Axis Grinding
Manufacturing using Walter five-axis precision grinding
supports cutting-edge sharpness, ball-profile accuracy
and repeatable tool geometry.
HELICHECK Profile Measurement
Walter HELICHECK PLUS profile measurement supports
accurate inspection of ball geometry, tool dimensions
and cutting profiles.
150× and 300× Inspection
150× optical inspection and 300× high-definition
appearance inspection help verify cutting edges,
coating condition and surface quality.
