Manufacturing Methodology: The Honing Process
Honing constitutes the critical final stage in the manufacturing of hydraulic cylinder tubes at Bos Hydraulic. While the initial cold drawing process establishes the fundamental tubular structure, the interior surface requires further refinement to meet the exacting standards of hydraulic applications. The honing process employs specialized abrasive tools that execute a compound motion—simultaneously rotating and oscillating within the tube—to remove minute amounts of material with exceptional control.
This sophisticated material removal process achieves two crucial objectives:
