Sunnen's SV-410 automated CNC honing system gives performance builders and production rebuilders a new level of control for achieving precise cylinder geometry, surface finish and crosshatch parameters for superior ring seal, uniform lubrication, minimal leak down and highest horsepower. Ideal for high-nickel and CGI blocks, the automated, high-horsepower honing system allows engine builders to deliver customized results quickly. The flexibility of the system allows for in-line 4- and 6-cylinder engines, as well as all V-6/8 blocks. The SV-410 combines automated operation with a 7.5 kW (10 hp) spindle to drive high-accuracy CBN and diamond tooling for short cycle times and high-quality results with minimal labor.
