Bilateral spiral end mill VHM ball-nosed for aluminium and plastics with upward chip removal – for 3D sculpting and machining

Index: SQ31.08.022.060.08R

Industrial bilateral spiral end mill made from solid carbide (VHM) with a ball-nosed geometry (Round Nose) and upward chip removal (positive). The arrangement of two cutting edges (Z2) with a full radius at the ends allows for precise contour milling, sculpting, engraving, and machining of curved 3D surfaces without leaving sharp steps. The right-hand helix effectively lifts the chips upwards, preventing accumulation in the cutting zone. Dedicated for finishing, cutting, and welding work in aluminium, plastics, and composite materials on CNC machining centres and overhead spindle mills. The finishing geometry combined with polished chip grooves prevents the material from sticking to the body. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Construction advantages and technical properties:

• Ball-nosed geometry (Round Nose): Full radius at the tool tips allows for precise 3D modelling, milling of spatial surfaces, and smooth transitions in internal radii.
• Bilateral Z2 construction (positive): Two cutting edges increase the stiffness of the mill and allow for efficient operation with smooth guidance in the material.
• Positive geometry (upward chip removal): Right-hand spiral lifts the chips upwards, protecting the lower machined surface from scratches by the chips.
• Polished chip grooves: The mirror-like surface of the spiral reduces friction and effectively counters the adherence of chips to the body.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid reduces vibrations and guarantees dimensional stability in precise details.
• Low grip roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards ensures vibration-free operation at very high speeds.

Purpose and scope of use:

The tool is designed for finishing 3D machining, sculpting, engraving, cutting, and welding in aluminium and plastics on CNC machining centres.

Used for machining materials such as: aluminium, plastics, and composite materials like CORIAN® and HPL.
