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 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.  LEARN MORE 

Lapping is a polishing process that employs abrasive surfaces that are rubbed against a part in order to achieve the desired finish. A lapping machine, such as Sunnen's SVL-2100 series, automates much of this polishing process, thus increasing accuracy and output.
