Request SpecificationsRecommended Mold Machining Applications
The range supports common mold manufacturing operations from material removal to cavity and profile finishing.
01
Slotting
Full-width slot machining in mold and die steels.
02
Side Milling
Peripheral machining of walls and external profiles.
03
Shoulder Milling
Controlled shoulder and flat-bottom machining.
04
Cavity Machining
Pockets, recessed areas and internal mold profiles.
05
Profile Finishing
Curved surfaces, transitions and mold contours.
Technical Performance Highlights
The carbide substrate, coating, anti-vibration geometry and controlled edge preparation 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 cutting-edge strength, toughness and wear resistance for demanding mold steels.
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.
88° / 92° Unequal End Teeth
The two-degree unequal end-tooth division disrupts repeated cutting forces, helping improve machining stability and reduce vibration marks on the workpiece surface.
35° / 37° Unequal Helix
Unequal peripheral helix angles help reduce harmonic vibration during side milling, cavity machining and contour operations.
0° to −5° Rake Geometry
The controlled rake-angle range reinforces the cutting edge and supports stable machining in 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 more consistent cutting and improved workpiece surface quality.
Automated Edge Polishing
Automated rubber-bonded diamond polishing helps maintain consistent edge preparation across the tool, with the preparation value controlled within ±0.003 mm.
Walter Five-Axis Grinding
Walter five-axis precision grinding equipment supports cutting-edge sharpness, dimensional accuracy and repeatable tool geometry for smoother cutting.
HELICHECK Profile Inspection
Tool profiles are inspected using Walter HELICHECK PLUS, supported by 150× optical inspection and 300× high-definition appearance inspection.
Radius Accuracy Within 3 μm
Ball nose and corner radius tools can be controlled to a radius accuracy within 3 μm for consistent cavity, profile and contour machining.
Recommended Workpiece Materials
Mainly recommended for mold, die, powder-metallurgy and selected tool steels with workpiece hardness up to HRC60.
