Description
Product Overview
This carbide ball nose end mill is designed for aluminum
cavity machining, curved surfaces, inclined features,
transition profiles and three-dimensional contour machining
of non-ferrous components.
The full-radius cutting profile provides continuous contact
along changing surface geometries. Imported carbide rods,
sharp positive-rake geometry, a 45° helix and 1200-grit
precision-ground cutting edges support smooth chip evacuation,
low cutting resistance and consistent aluminum surface quality.
Recommended Aluminum Machining Applications
The full-radius ball nose profile supports aluminum
operations requiring continuous cutting contact across
cavities, slopes, curved surfaces and three-dimensional contours.
Cavity Machining
Suitable for recessed areas, internal profiles
and aluminum cavities with continuously changing
cutting engagement.
Curved-Surface Milling
Designed for rounded profiles, free-form surfaces
and complex aluminum component geometries.
Inclined-Surface Machining
Supports sloped surfaces and transition features
where the effective cutting position changes
continuously along the toolpath.
3D Contour Machining
Suitable for semi-finishing and finishing of
three-dimensional aluminum profiles and detailed
surface features.
Designed for Aluminum Surface Machining Challenges
Aluminum can generate long ductile chips, built-up edge,
burrs and visible tool marks. The sharp cutting geometry,
sufficient flute space and precision ball profile help
maintain smooth chip flow and stable surface machining.
Chip Evacuation and Cutting Efficiency
- Standard two-flute structure provides large chip spaces
- 45° helix supports smooth aluminum-chip movement
- Positive rake geometry reduces cutting resistance
- Efficient evacuation helps reduce chip recutting
- Suitable for cavities and curved surfaces
- Low tool runout is recommended
Surface and Radius Stability
- Full-radius profile supports continuous cutting contact
- 1200-grit grinding improves cutting-edge sharpness
- Sharp geometry helps reduce material deformation
- DLC option helps reduce friction and aluminum adhesion
- Precision radius supports repeatable 3D contours
- Rigid toolholding improves finished-surface quality
Ball Nose Geometry and Cutting Performance
The carbide substrate, full-radius ball profile, positive
rake geometry, helix angle and precision grinding work
together to support stable aluminum cavity and contour machining.
0.8 μm Carbide Grain Size
Imported carbide rods with an approximately 0.8 μm
grain size support consistent cutting-edge geometry,
wear resistance and stable production quality.
10% Cobalt Content
The 10% cobalt content provides a balance of carbide
hardness, cutting-edge strength and substrate toughness
for aluminum and non-ferrous machining.
Full-Radius Ball Nose Profile
The full-radius cutting profile provides continuous
contact during cavity machining, curved surfaces,
slopes and three-dimensional contour milling.
Standard Two-Flute Structure
The standard two-flute configuration provides
sufficient flute space for aluminum-chip evacuation
during cavity and surface machining.
45° Helix Geometry
The 45° helix supports smooth cutting engagement,
stable upward chip movement and reduced cutting
resistance during aluminum contour machining.
6° Positive End Rake
The positive end-edge rake helps reduce cutting
pressure near the ball tip and supports cleaner
cavity and bottom-area machining.
12° Positive Peripheral Rake
The positive peripheral rake creates a sharper
cutting action along the effective cutting area
of the ball profile.
1200-Grit Precision Grinding
Fine grinding with a 1200-grit grinding wheel
helps maintain edge sharpness, reduce microscopic
defects and limit burr formation.
Large Chip-Evacuation Space
Sufficient flute space helps guide aluminum chips
away from the cutting area and reduces the risk
of chip packing and recutting.
Low Cutting Resistance
Sharp positive-rake geometry helps reduce rubbing,
cutting pressure and unnecessary heat generation
during aluminum surface machining.
Reduced Built-Up Edge
Sharp cutting edges, smooth chip movement and
the optional DLC coating help reduce aluminum
adhesion under suitable machining conditions.
Improved Surface Consistency
Precision-ground cutting edges and controlled
ball geometry help reduce visible tool marks
between adjacent machining passes.
Ball Radius Accuracy Within 5 μm
Walter HELICHECK PLUS measurement supports
ball-radius and profile control within approximately
5 μm for repeatable cavities and 3D contours.
50× Microscopic Edge Inspection
Every tool is inspected under 50× magnification
to check for visible cutting-edge chipping,
serrations and abnormal defects.
Walter Five-Axis Grinding
Walter five-axis precision grinding supports
stable dimensions, consistent flute geometry
and repeatable ball nose profiles.
Consistent Batch Production
Precision grinding and multi-stage inspection
help maintain dimensional, radius and cutting-edge
consistency across wholesale and OEM batches.
Uncoated and DLC Rainbow-Coated Options
Coating selection should be based on the aluminum grade,
silicon content, cutting parameters, lubrication condition
and required tool life.
