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

Index: CPU.03.010.045.03R

Industrial multi-edge mill made of solid sintered carbide (VHM) with a spherical geometry and upward chip evacuation. The multi-edge system with a full radius front is designed for precise 3D surface modelling, sculpting, and engraving in demanding 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 carries the chips upwards, preventing accumulation in the cutting zone and protecting the surface of the workpiece. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system from wear.

Design advantages and technical properties:

• Spherical geometry for 3D shaping: Full radius at the tips enables smooth machining of curved and shaped surfaces without leaving sharp edges.
• Multi-edge cutting system: Multi-edged teeth gently and precisely shear the composite, preventing layer separation and fibre fraying.
• Upward chip evacuation (positive): The right-hand chip channel lifts dust and chips, protecting the machining area from scratches.
• High-hardness sintered 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:

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

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