Multi-blade VHM spiral mill for composites – 3D machining without delaminating the material

Index: CPU.04.015.060.04R

Industrial multi-blade mill made from solid carbide (VHM) with a spherical geometry and upward chip ejection. The multi-edge configuration with a full frontal radius is designed for precise 3D surface modelling, sculpting, and engraving in difficult composite materials. The special cutting design cleanly shears the material structure, preventing delamination and pulling of glass and carbon fibres. The right-hand helical flutes efficiently remove chips upwards, preventing their accumulation in the cutting zone and protecting the surface of the workpiece. The ground shank in accuracy class H6 eliminates radial runout, safeguarding the machine's drive system from wear.

Design advantages and technical properties:

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

Intended use and range of application:

The tool is designed 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.
