Recommended Machining Applications

The full-radius ball nose profile provides continuous cutting
contact during titanium alloy cavity, curved-surface and
three-dimensional profile machining.

01

Cavity Machining

Suitable for titanium alloy cavities, recessed areas
and internal profiles with continuously changing
cutting engagement.

02

Curved-Surface Milling

Designed for free-form surfaces, rounded profiles
and complex titanium component geometries.

03

Inclined-Surface Machining

Supports sloped surfaces and transition features
where the effective cutting position changes
continuously along the toolpath.

04

3D Contour Machining

Suitable for controlled semi-finishing and finishing
of three-dimensional titanium profiles and detailed
surface features.

Designed for Titanium Alloy Machining Challenges

Titanium alloys generate concentrated cutting heat, strong
material adhesion and changing cutting loads. The coating,
flute profile and cutting geometry are designed to maintain
stable chip flow and reduce built-up edge.

Chip and Heat Control

  • U-shaped flute provides increased chip capacity
  • Arc-formed groove supports smoother chip movement
  • 43° helix improves chip evacuation
  • 8° positive rake reduces cutting resistance
  • Efficient evacuation helps remove cutting heat
  • Suitable for controlled semi-finishing

Adhesion and Surface Stability

  • HSR118 coating helps reduce titanium adhesion
  • High hot hardness supports elevated cutting temperatures
  • Unequal geometry helps suppress repeated vibration
  • Precision ball profile supports consistent contours
  • Controlled edge preparation improves edge uniformity
  • Low runout and rigid toolholding are recommended

Ball Nose Geometry and Cutting Performance

The carbide substrate, HSR118 coating, arc-formed flute,
precision ball radius and controlled edge preparation work
together to support stable titanium contour machining.

01

Ultra-Fine Carbide Substrate

Ultra-fine carbide powder with a grain size below
0.6 μm supports cutting-edge strength, wear resistance
and consistent ball nose geometry.

02

12% Cobalt Content

A 12% cobalt content provides a balance of carbide
toughness, cutting-edge strength and impact resistance
during changing titanium cutting contact.

03

HSR118 High-Temperature Coating

The HSR118 coating provides high hot hardness and
stable wear resistance at operating temperatures
up to approximately 1200°C.

04

Anti-Adhesion Surface Performance

The coating is designed to reduce material affinity
with titanium, helping limit adhesion, built-up edge
and unstable cutting at elevated temperatures.

05

Full-Radius Ball Nose Profile

The full-radius cutting profile provides continuous
contact during cavity, curved-surface, inclined-surface
and three-dimensional contour machining.

06

Arc-Formed Flute Design

The arc-shaped flute helps distribute cutting loads
and support stable chip flow during difficult titanium
alloy surface machining.

07

U-Shaped Flute Profile

The U-shaped flute provides increased chip capacity
and supports efficient chip evacuation from cavities
and complex surface features.

08

8° Positive Rake Angle

The positive rake geometry supports cleaner cutting
and helps reduce cutting resistance, rubbing and
localized heat generation.

09

43° Helix Geometry

The 43° helix supports smooth engagement, stable
chip movement and controlled cutting forces during
curved-surface and cavity machining.

10

87° / 93° Unequal Cutting Geometry

The unequal cutting division interrupts repeated
cutting forces, helping suppress vibration and
improve stability during contour machining.

11

Ball Radius Accuracy Within 3 μm

Precision grinding and profile inspection help control
the ball radius within 3 μm for repeatable cavities,
curved surfaces and three-dimensional contours.

12

Fluid-Blasting Edge Preparation

Fluid blasting helps reduce microscopic burrs and
stabilize the cutting edge, supporting smoother
cutting and improved workpiece surface quality.

13

Automated Edge Polishing

Automated rubber-bonded diamond polishing helps
maintain consistent preparation across the cutting
edges, with the value controlled within ±3 μm.

14

Walter Five-Axis Grinding

Walter five-axis precision grinding supports
cutting-edge sharpness, ball-profile accuracy
and repeatable tool geometry.

15

HELICHECK PLUS Profile Measurement

Walter HELICHECK PLUS profile measurement supports
accurate inspection of the ball radius, tool dimensions
and cutting geometry.

16

150× and 300× Inspection

150× optical inspection and 300× high-definition
appearance inspection help verify cutting edges,
coating condition and surface quality.
