Multi-edge VHM end mill for composites – neutral chip ejection and protection against delamination

Index: CSS.12.040.090.12R

Industrial multi-edge end mill made from solid carbide (VHM) with a simple cutting edge geometry (neutral chip ejection to the sides). Dedicated to precision machining of fibrous composites, it eliminates the risk of delamination of the structure and the pulling of glass and carbon fibres. The arrangement of the simple cutting edges does not generate vertical forces (neither pressing nor lifting), which guarantees a smooth finish and no tear-outs on both the upper and lower surfaces of the plate. The tool performs well in cutting, grooving, and slotting on CNC machining centres and overhead milling machines. A ground shank in class H6 protects the spindle from vibrations and prevents radial run-out.

Design advantages and technical properties:

• Multi-edge geometry for composites: The multi-edge cutting arrangement precisely shears the material, preventing layer separation and fibre fraying.
• Simple geometry (side ejection): The neutral cutting direction eliminates pressure and lifting of the workpiece, ensuring clean edges on both sides.
• Solid carbide (VHM): Wear-resistant material structure guarantees long service life when machining abrasive materials.
• Low shank roughness (Ra ≤ 0.3 µm): Ground shank protects the spindle cone and prevents tool shifting in the holder.
• Dynamic balancing G2.5: Balancing according to ISO standards ensures stable and vibration-free operation at very high speeds.

Intended use and application range:

The tool is designed for cutting, grooving, and slotting operations in composite materials 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.
