High-speed finishing to perfection

The 3D Finish revolutionises finishing on 5-axis milling machines and machining centres. The tools work in a similar way to finishing using a ball nose end milling cutter, yet increase the width of cut due to their circle segments boasting large radii. Even at higher widths of cut, significantly improved surfaces are achieved and machining times are drastically reduced.

Advantages

  • Highly cost-effective
    The large radii make higher widths of cut possible, which significantly reduces processing times
  • Improved surfaces
    Despite shorter machining times, improved surface qualities are achieved thanks to the large radii
  • HA shank
    Ideal runout and balance quality due to the cylindrical shank
  • Universal application
    The 3D Finish is suitable for use on steel, stainless steels, cast iron, non-ferrous metals, heat-resistant steels and hardened steel

Large variety of geometries in the 3D Finish product range

All versions in the 3D Finish range boast a tight geometrical tolerance of ± 0.01 mm.

Comparison – ball nose end milling cutters vs. 3D Finish

BALL NOSE END MILLING CUTTERS

  • Radius depends on the tool diameter
  • Only low widths of cut are possible; linked to the small radius
  • Tools with a large diameter/radius are expensive due to the high carbide content, e.g. diameter 16 mm radius 8 mm

3D FINISH – OVAL SHAPE

  • Radius does not depend on the tool diameter
  • High depths of cut possible owing to the large radius
  • Tools with a large radius and small shank diameter are more economical as the carbide content is lower, e.g. diameter 16 mm, radius 1500 mm

Results

Thanks to the enlarged radius, stepovers can be significantly increased. You can also meet the highest demands of dimensional stability and accuracy.

Product range

With the 3D Finish range, WNT offers the most extensive product spectrum on the market and can provide the ideal milling cutter geometry for any component shape. This means you not only benefit from quicker machining times and improved surface qualities, but also enjoy maximum flexibility and long-term tool availability.

3D Finish – barrel shape

  • Suitable for easily accessible areas

3D Finish – oval shape

  • Suitable for easily accessible flanks
  • Not suitable for deep areas

3D Finish – taper shape

  • Suitable for steep walls and deep cavities
  • α/2 is the angle to the surface to be used
  • If the surface exhibits a tilt angle of α/2, the surface can also be machined on three axes

3D Finish – taper shape

  • Suitable for flat areas
  • α/2 is the angle to the surface to be used
  • If the surface exhibits a tilt angle of α/2, the surface can also be machined on three axes

3D Finish – lens shape

  • Suitable for flat areas
