The SV-3100 is the next step in the continuing evolution of the Sunnen SV series, including a new look combined with the new Sunnen2 controls.
The SV-3100 Series is capable of holding the industry’s tightest production environment tolerances as fine as 0.00025 mm (0.000010 in.) tolerances far superior to I.D. grinding.

The SV-3100 is a precision solution focused on small bore applications of 19 mm (.75 in.) and less.
