Multi-edge spiral end mill VHM ball for composites – 3D machining without material delamination

Index: CPU.12.040.090.12R

Industrial multi-edge end mill made of solid carbide (VHM) with a ball geometry and upwards chip evacuation. The multi-edge system with a full front radius is designed for precise modelling of 3D surfaces, sculpting, and engraving in challenging composite materials. The special cutting design cleanly shears the material structure, preventing delamination and the pulling out of glass and carbon fibres. The right-hand helical flute efficiently removes chips upwards, preventing accumulation in the cutting zone and protecting the surface of the workpiece. The ground shank with H6 accuracy class eliminates radial runout, safeguarding the machine's drive system from wear.

Design advantages and technical properties:

• Ball geometry for 3D shaping: Full radius on the ends allows smooth machining of curved and contoured surfaces without leaving sharp edges.
• Multi-edge cutting system: The multi-edge tooth design gently and precisely shears the composite, preventing layer separation and fibre fraying.
• Upward chip evacuation (positive): The right-hand chip channel lifts dust and chips, protecting the machined area from scratching.
• High hardness carbide (VHM): The monolithic structure exhibits wear resistance when machining highly abrasive materials.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank prevents slipping in the holder and secures the spindle taper.
• Dynamic balancing G2.5: Compliance with ISO standards ensures smooth and vibration-free operation at very high speeds.

Intended use and application range:

The tool is designed for finishing 3D machining, sculpting, engraving, and contour cutting of composites on CNC machines.

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