Two-edged spiral end mill VHM ball from the SQ32 series for 3D reliefs

Index: SQ32.48.159.635.48R

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

Design advantages and technical properties:

• Extended body with undercut: Special tapering of the cutting part allows for safe and precise work in deep cuts and 3D forms without the risk of body collision with the material.
• Polished chip grooves: Advanced polishing of the groove efficiently evacuates chips, prevents workpiece sticking, and reduces cutting resistance.
• Ball construction Z2 with upward chip evacuation: Right-hand screw line ejects chips upwards, ensuring cleanliness in the cutting zone and high surface quality.
• Finishing edge geometry: Precisely ground cutting edges allow for a clean edge finish without the need for additional processing.
• Low grip roughness (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.

Purpose and scope of application:

The tool is designed for precise machining of forms and 3D models, cutting, as well as jointing and edge levelling on CNC machining centres.

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