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

Index: CNR.06.024.060.06R

Industrial rough milling cutter made of solid carbide (VHM) with a rosette-type face (CNR) and neutral blade geometry (chip ejection sideways). The front design facilitates axial entry into the material along the Z-axis, reducing cutting resistance and eliminating the risk of structural damage upon entry. The multi-edge cutting system crushes the material, preventing the delamination of composites and the 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 for efficient cutting, grooving, and bonding on CNC machining centres. The ground shank in H6 class protects the spindle against vibrations and prevents radial runout.

Design advantages and technical properties:

• Rosette face geometry (CNR): The dedicated face design reduces resistance during axial plunging, allowing stable entry into the material.
• Rough multi-edge system: The dense tooth geometry finely crushes chips, preventing layer separation and edge fraying.
• Neutral chip ejection sideways: Lack of pressure and lifting ensures stable cutting and a clean profile on both sides.
• Solid 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 balance G2.5: Compliance with ISO standards enables safe and vibration-free operation at very high speeds.

Application and scope of use:

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 reinforced plastics (GFRP), CORIAN® composite panels, HPL laminates, and plywood.
