Two-Edged Spiral Ball End Mill VHM from the SQ32 Series for 3D Reliefs

Index: SQ32.12.030.120.12R

Industrial spiral ball end mill made from solid carbide VHM from the SQ32 series, featuring positive geometry (chip removal upwards). The tool has an extended body with a neck above the working part, designed for deep machining of 3D models, cutting, as well as seam welding and edge alignment on CNC machines. The polished surface of the chip groove prevents the machined material from sticking and facilitates quick evacuation of chips. The ball radius on the front combined with the finishing geometry of two cutting edges (Z2) allows for achieving smooth surfaces. The ground shank in accuracy class H6 eliminates radial runout, protecting the drive system and guaranteeing a high level of machining stability.

Design Advantages and Technical Properties:

• Extended body with a neck: The special tapering of the working part enables safe and precise operation in deep cuts and 3D forms without the risk of collision between the body and the material.
• Polished chip grooves: Advanced polishing of the grooves effectively removes chips, prevents buildup of the machined material and reduces cutting resistance.
• Ball Z2 geometry with upward chip removal: The right-hand helical structure ejects chips upwards, ensuring cleanliness in the cutting zone and high surface quality.
• Finishing geometry of the cutting edges: Precisely ground cutting edges allow for a clean finish of the edges without the need for additional machining.
• Low surface roughness of the shank (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards ensures quiet and stable operation at high rotational speeds.

Intended Use and Scope:

The tool is intended for precise machining of forms and 3D models, cutting, as well as seam welding and edge alignment on CNC machining centres.

It performs excellently in machining materials such as: aluminium, CORIAN® type composites and HPL boards.
