Sunnen SV-30 honing machine features auto step-and-repeat capability

Sunnen will display its SV-30 honing series, the next generation in the line of Cylinder King® machines.

Several models of this machine incorporate step-and-repeat capability, allowing automatic bore-to-bore processing for inline and V-block configurations, reducing setup time and improving bore quality. New Sunnen GH-LF tooling is used for automatic operation.

The machine also includes spindle reversal; standard bore oversize setup; and automatic tool protection at the top and bottom of the bore, which verifies an unobstructed stroke before starting a cycle.

Models have either a variable-speed, 6-HP servo or 5.5-HP induction spindle motor, producing speeds from 50 to 600 RPM. A 3.4-HP servo ball screw system produces up to 100 true vertical strokes per minute with a stroke length up to 27.75 in.

The new series can hone bores with inside diameters from 0.75 to 8 in. A 48- by 30-in. work envelope allows the processing of large parts.
