Multi-edge spiral end mill VHM for composites – clean cutting without delamination of the material

Index: CPS.12.040.090.12R

The industrial multi-edge mill made from solid carbide (VHM) is designed for efficient machining of demanding composite materials. The special arrangement of cutting edges protects the material from delamination and the pulling out of glass and carbon fibres during cutting. The right-handed spiral design (positive geometry) effectively removes chips upwards, preventing accumulation in the cutting area and protecting the bottom edge of the workpiece. The tool is suitable for precise sawing, formatting, and edge truing on CNC machining centres and vertical spindle milling machines. The precisely ground shank in accuracy class H6 eliminates radial runout, protecting the machine drive from premature wear.

Design advantages and technical properties:

• Geometry for composite materials: The multi-edge blade arrangement cleanly cuts through the structure of the material, preventing fraying and layer separation at the edges.
• Chip evacuation upwards (positive): The right-handed chip channel efficiently lifts dust and chips, protecting the underside of the workpiece from scratching.
• Cemented carbide with high hardness (VHM): The monolithic design ensures wear resistance when working with materials of high abrasiveness.
• Low grip roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and secures the spindle cone.
• Dynamic balancing G2.5: Balancing according to ISO standards enables safe and vibration-free operation at high speeds.

Intended use and range of application:

The tool is designed for formatting, cutting, and edge truing operations in fibrous composites on CNC machines.

Used in the machining of materials such as: fibre reinforced plastics with carbon fibre (CFRP), glass fibre (GFRP), CORIAN® composite sheets, and HPL laminates.
