New Vertical Honing Systems Feature Sunnen2 Control with "Auto-Snug" -- Taking the Guesswork Out of Tool Setup
The new Sunnen SV-35 Series honing machines balance power and precision to achieve expert results on a wide range of parts including engine cylinder blocks, liners and other applications that require a precision bore.
The SV-35 includes a new in-house designed Sunnen2 control with simplified menus and storage of 1000+ setups for quick and easy changeovers. The new control helps reduce labor costs and increases productivity, as multiple operators can be quickly trained to run the system. When used with the wide range of Sunnen-made abrasives, tooling and coolants, the U.S.- built SV-35 produces ideal bore roundness and surface finish in a variety of part types and materials.
The new Sunnen2 control ensures automatic, consistent bore-to-bore geometry and finish, without constant adjustment by the operator. According to Sunnen, the focus during development of the new Sunnen2 control was ease of use and setup.
New features of the Sunnen2 include constant cross hatch capability and tool "auto snug." Constant cross hatch finish of the bore is achieved by entering the desired bore angle in the setup. The Sunnen2 control is constantly changing the speeds of the servo spindle and stroker to ensure the cross hatch is the same from top to bottom of the bore. The "Auto-Snug" feature takes the guesswork out of tool setup making the process simple and repeatable.
The rugged 15.6-inch (396 mm) color touchscreen with intuitive controls provides a real-time display of the full-bore cross section during the process. Screen-selected languages include English, German, Spanish and Chinese. The control's programmable Auto-Dwell feature automatically corrects taper anywhere in the bore for unattended operation. Two-stage GH honing tools with diamond abrasives, CBN abrasives or PB brushes can combine roughing and finishing operations in one tool for high productivity.
Three new standard SV-35 models include two step-and-repeat-capable versions, allowing automatic bore-to-bore processing for in-line and V-block configurations. The step-and-repeat feature allows machine operators to complete other tasks while the machine hones the part automatically. A base SV-35 model has a manual X-axis for low-volume applications.
