New Honing Process Produces High-Precision in Manufacturing

Single Stroke Honing from Sunnen is a single-pass process that sizes and finishes a bore with a series of progressively larger superabrasive tools adjusted to a pre-set diameter. Single Stroke Honing tools rotate while passing through the bore one time and then withdrawing. The machine's servo-controlled stroking system provides flexibility with adjustable speed and various feed profiles, such as pecking, short stroke, dwell, etc. Column feed and spindle speed can be varied throughout a cycle using the machine control. 
Developed in Europe by Sunnen Products Company, the Single Stroke Honing® process for cast-iron hydraulic valve bodies produces less than 2 µm cylindricity in bores, achieving almost 200 percent more precision than previously possible.
