Sone303 Top · Working & Recent

The "Top" designation in the SONE303 series often refers to the upper tolerance class.

Assuming a solid cylindrical model for the standard SONE303 Top, the mass moment of inertia ($I$) about the central axis is calculated as: $$ I = \frac12 M r^2 $$ Where $M$ is the mass and $r$ is the radius (15 mm). The low tolerance for roundness minimizes vibration during rotation, reducing the net unbalanced force ($F_u$) described by: $$ F_u = m_e \cdot r \cdot \omega^2 $$ Where $m_e$ is the eccentric mass. The precision of the SONE303 Top ensures $m_e$ remains negligible. sone303 top

Due to its homogenized hardness, standard HSS tools will dull quickly. Switch to: The "Top" designation in the SONE303 series often
