The system features zero shut-off for automatic cycle control with minimal operator attention. Furthermore, the 'rough and finish' honing capability eliminates preliminary reaming, boring and grinding operations to help lower component costs, Sunnen says.
The SSH-1680 is suited to parts with keyways, splines and blind bores. According to its maker, an adjustable spindle allows the operator to eliminate mandrel run-out, making it easy to achieve precision bore geometry. Multiple land and tandem bores are bridged with Sunnen's long stones, maintaining alignment and consistent size without camber or washout.
The machine handles part lengths up to 250 mm at bore diameters from 3-60 mm. The stroke rate is 80-310 spm (adjustable incrementally), while spindle speed is 250-2500 rpm. The SSH-1680 accepts all standard Sunnen tooling, including K, P20 and P28 mandrels.
