Fuel Injectors Honing Machines

SV-2000 Series Vertical Honing Machines
The SV-2000 Series is capable of holding the industry’s tightest production environment tolerances – as fine as 0,00025 mm (0.000010
inch) – tolerances far superior to I.D. grinding.

Built on a proven, modular platform, the SV-2000 Series can be easily customized and automated to suit your exact specifications – whatever your needs demand, from multiple spindles to air gaging. Plus, this flexible system supports both single-pass and conventional reciprocating
honing. Brushing stations can also be added.

Perfect for mid- to high-production manufacturers, the SV-2000 Series delivers the lowest
cost per honed part with the tight bore tolerances you expect from Sunnen.

Bore Diameter Range (I.D.):
3 mm – 65 mm
(.118 inch – 2.56 inch)*
