Multi-flute spiral end mill VHM for composites with downward chip ejection – clean top edge and protection against delamination

Index: CVS.06.020.070.06R

Industrial multi-flute spiral end mill made from solid carbide (VHM) with negative geometry (downward chip ejection). The specialised multi-edged design has been developed for the machining of composite materials, eliminating the risk of delamination and pulling out of glass and carbon fibres. The left-hand helical flute directs the cutting forces and material downward, pressing the workpiece against the table and ensuring a clean top edge without tear-outs. Designed for precision cutting, bonding, grooving, and notching of composites on CNC machining centres and overhead milling machines. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Structural advantages and technical properties:

• Multi-flute geometry for composites: The multi-edged cutting arrangement cleanly shears the material structure, effectively preventing delamination and pulling out of glass and carbon fibres.
• Negative geometry (downward chip ejection): The left-handed chip flute directs debris downward and presses the workpiece to the substrate, ensuring a clean finish on the top edge of the detail.
• Solid carbide (VHM): The rigid and abrasion-resistant solid structure ensures high tool longevity when machining highly abrasive materials.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards ensures vibration-free operation at very high speeds.

Application and scope of use:

The tool is intended for cutting, bonding, grooving, and notching operations on composite materials in CNC machining centres.

Used in the machining of materials such as carbon fibre reinforced plastics (CFRP), glass fibre reinforced plastics (GFRP), and composites like CORIAN® and HPL.
