Sunnen releases SVL-2115 automated lapping machine

June 21, 2016 – Sunnen's SVL-2115 automated lapping machine is designed to bring increased productivity and part consistency to what is traditionally a manual process. Based on the same machine platform as the popular SV-2100 honing system, the SVL-2115 provides single setup processing of hydraulic valves, sleeves, fuel system components and other parts that are prone to distortion when honed. The walkaway system uses an index table to automatically lap and air gage bores throughout the cycle. Gage readings are fed back to the control and the cycle is repeated until the parts are within spec.

The Sunnen lapping system handles workpiece diameters from 6.5 to 20 mm (0.26 to 0.70 in) and lengths up to 12 times the bore diameter, not to exceed 200 mm (7.87 in). Spindle speed range is 100-2000 rpm during lapping, but is capable of slow speeds for non-powered steps, such as lapping paste application or slow-rotation bore entry. Stroker speed is 0-350 SPM, with stroke length optimized to achieve a high degree of cylindricity.

Sunnen has developed laps and gage probes to accompany this new system, and easy tooling and probe changeovers accommodate frequent changes during the course of a shift. A stack light allows operators to monitor cycle completions or faults from a distance, while a light curtain is standard. The lapping system is available with Sunnen’s SVF filtration system.
