Multi-Stage Automated Lapping Machine
August 1, 2016
Sunnen's new 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 SV-2100 honing system, the SVL-2115 provides single set-up 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 gauge bores throughout the cycle. Gauge readings are fed back to the control and the cycle is repeated until the parts are within spec.
"Automated lapping is more consistent than manual and there are fewer workers with the skills necessary for precision manual lapping. For very expensive parts, an automatic lapping process reduces the possibility of ruined parts due to human error," said Phil Hanna, Product Manager, Sunnen. "Since lapping is usually the last process during the machining of a workpiece, if the lapping is not correct, all the work up to that point is wasted."
The Sunnen lapping system handles workpiece diameters from 6.5 to 20 mm (0.26" to 0.70") and lengths up to 12 times the bore diameter, not to exceed 200 mm (7.87"). Spindle speed range is 100-2,000 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 gauge 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 new SVF filtration system.
