Multi-edge VHM spiral mill composite roughing cutter – rosette front (CNR) and machining without delamination

Index: CNR.10.030.090.10R

Industrial roughing mill made of solid carbide (VHM) with a rosette-type front (CNR) and neutral cutting edge geometry (chip ejection to the sides). 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 fragments the material, preventing delamination of composites and pulling out glass and carbon fibres. The neutral cutting direction does not create axial forces (either pressing or lifting), ensuring a high standard of edge finish on both sides of the plate. Dedicated for efficient cutting, grooving, and jointing on CNC machining centres. A ground shank in class H6 secures the spindle against vibrations and prevents radial run-out.

Design advantages and technical properties:

• Rosette front geometry (CNR): Dedicated front design reduces resistance during axial immersion, allowing stable entry into the material.
• Multi-edge roughing configuration: Dense tooth structure finely chips the material, preventing layer separation and edge fraying.
• Neutral chip ejection to the sides: The absence of pressure and lifting forces guarantees 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 balancing G2.5: Compliance with ISO standards allows safe and vibration-free operation at very high speeds.

Application and scope of use:

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

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