Multi-edge ball end mill made of solid carbide for composites – 3D machining without material delamination

Index: CPU.08.030.080.08R

Industrial multi-edge mill made from solid carbide (VHM) with a ball geometry and upward chip ejection. The multi-edge system with a full end radius is designed for precise 3D surface modelling, 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 spiral efficiently lifts the chips upwards, preventing accumulation in the cutting zone and protecting the surface of the workpiece. A ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system from wear.

Design advantages and technical properties:

• Ball geometry for 3D shaping: The full radius on the ends allows for smooth machining of curved and shaped surfaces without leaving sharp steps.
• Multi-edge cutting system: Multi-edged teeth gently and precisely shear the composite, preventing layer separation and fraying of fibres.
• Upwards chip evacuation (positive): The right-hand chip channel lifts dust and chips, protecting the working area from scratches.
• High hardness carbide (VHM): The monolithic structure shows resistance to wear when machining highly abrasive materials.
• Low surface roughness of the shank (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 intended for finishing 3D machining, sculpting, engraving, and contour cutting of composites on CNC machines.

Used for machining materials such as: fibre-reinforced plastics (CFRP), glass fibre (GFRP), CORIAN® composite sheets, and HPL laminates.
