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

Index: CPS.08.030.080.08R

Industrial multi-edge end mill made from solid carbide (VHM), designed for efficient machining of demanding composite materials. The special arrangement of cutting edges protects the material from delamination and extraction of glass and carbon fibres during cutting. The right-hand spiral flute (positive geometry) efficiently lifts the chips upwards, preventing their accumulation in the cutting zone and protecting the bottom edge of the workpiece. The tool performs well in precision cutting, formatting, and edge aligning on CNC machining centres and overhead milling machines. The precisely ground shank in accuracy class H6 eliminates radial runout, protecting the machine drive system from premature wear.

Construction advantages and technical properties:

• Geometry for composite materials: The multi-edge blade arrangement cleanly cuts through the structure of the material, preventing fraying and delamination of layers at the edges.
• Chip evacuation upwards (positive): The right-hand fluting efficiently lifts dust and chips, protecting the underside of the machined sheet from scratching.
• High hardness carbide (VHM): The monolithic design ensures abrasion resistance when working with highly abrasive materials.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and secures the spindle taper.
• Dynamic balancing G2.5: Balancing according to ISO standards enables safe, vibration-free operation at high speeds.

Intended use and scope of application:

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

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