(Sunnen: St. Louis, MO) -- Sunnen’s new SVL-2115 automated lapping machine brings 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-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.

“Automated lapping is more consistent than manual, and there are fewer workers with the skills necessary for precision manual lapping,” says Phil Hanna, product manager at Sunnen. “For expensive parts an automatic lapping process reduces the possibility of ruined parts due to human error. Since lapping is usually the last process during the machining of a workpiece, if the lapping isn’t correct, all the work to get the part produced up to that point is wasted.”
