SVL-2115 Lapping Machine Laps and Air Gages in One Setup

Sunnen's SVL-2115 automated lapping machine enables increased productivity and part consistency to what is traditionally a manual process. The machine enables single setup processing of hydraulic valves, sleeves, fuel system components and other parts that are prone to distortion when honed. The system control is designed for unattended operation and automatically laps 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 specifications.

The lapping tools are available for workpiece diameters from 6.3 to 45 mm (0.25" to 1.77") and as long as 12x the bore diameter, not to exceed 200 mm (7.87"). Spindle speed range is 100-2000 rpm during lapping, but it is said to be capable of slow speeds for non-powered steps, such as lapping paste application or slow-rotation bore entry. Stroking speed is 0 to 350 spm.

Because of the ergonomics of the machine, repetitive motion injuries often encountered with manual lapping have been virtually eliminated. There is no need to touch a moving part during the lapping process and a light curtain is standard, so safety is improved. Tooling and probe change-overs accommodate multiple different part runs during the course of a shift. A stack light enables operators to monitor cycle completions or faults from a distance.
