Multi-edge spiral milling cutter VHM for composites – rosette front (CNR) and delamination-free machining

Index: CNR.04.018.060.04R

Industrial rough milling cutter made from solid sintered carbide (VHM) with a rosette front (CNR) and neutral cutting edge geometry (chip ejecting to the sides). The front design facilitates axial entry into the material along the Z-axis, reducing cutting resistance and eliminating the risk of damaging the structure upon entry. The multi-edge cutting system breaks the chips, preventing delamination of composites and pulling out of glass and carbon fibres. The neutral cutting direction does not generate axial forces (either compressive or lifting), ensuring a high standard of edge finish on both sides of the plate. Dedicated to efficient cutting, grooving and bonding on CNC machining centres. The ground shank in class H6 protects the spindle from vibrations and prevents radial runout.

Structural advantages and technical properties:

• Rosette front geometry (CNR): The dedicated face arrangement reduces resistance during axial immersion, allowing stable entry into the material.
• Multi-edge roughing system: Dense teeth finely crush chips, preventing layer separation and edge fraying.
• Neutral chip ejection to the sides: The lack of pressure and pulling of the workpiece guarantees stable cutting and a clean profile on both sides.
• Monolith of sintered carbide (VHM): High hardness and wear resistance ensure longer tool life when machining abrasive materials.
• Low shank roughness (Ra ≤ 0.3 µm): Precisely ground shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing G2.5: Compliance with ISO standards enables safe and vibration-free operation at very high speeds.

Purpose and range of application:

The tool is designed for rough cutting operations, axial entry into the material along the Z-axis, cutting and bonding in composites and plywood on CNC machines.

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