Okuma's VSST allows users to cut threads without chatter.

Eliminating harmonics, which can produce tool chatter or poor surface finish, is critical for maximizing CNC lathe productivity. Harmonic Spindle Speed Control (HSSC) and Variable Spindle Speed Threading (VSST) are functions built into Okuma’s Thinc-OSP CNC control that are harmonics problem solvers. HSSC and VSST are particularly useful when machining parts with high L/D ratios, thin-walled parts or thin-walled parts with threads.

Avoiding scrap caused by harmonic-induced vibration can be a challenge using conventional solutions. HSSC and VSST functions on an Okuma CNC lathe make it easier to achieve consistent surface finishes on parts, the company says.
