Honing vs Roller Burnishing

slide
When it comes to finishing hydraulic cylinder tubes, two of the most popular methods are honing and roller burnishing (often coupled with skiving). Both processes aim to improve the surface finish and dimensional accuracy of tubes, but they differ significantly in their approach, benefits, and ideal applications.

At Lasani Fluid Power LLP, we understand the importance of selecting the right finishing process for your hydraulic tubes to ensure optimal performance, longevity, and cost-effectiveness. Below, we provide a detailed comparison of these two methods to help you make an informed decision.

Honing vs. Roller Burnishing: Understanding the Difference

1. Honong Process

  • Definition: Honing is an abrasive machining process that uses a series of abrasive stones or sticks to remove material from the interior surface of a cylinder or tube. This process is ideal for achieving a very smooth surface finish and tight dimensional tolerances.
  • Applications: Commonly used for finishing hydraulic cylinder tubes where superior surface finish, lubrication retention, and precise bore size are critical.
  • Advantages:
    • Excellent surface finish (Ra as low as 0.05 µm)
    • Superior lubrication retention due to cross-hatch pattern
    • Precise control over bore size
  • Limitations:
    • Slower process than skiving and roller burnishing
    • Higher initial capital cost for honing machines
    • More material waste compared to roller burnishing

2. Skiving and Poller Burnishing Process:

  • Definition: Skiving and roller burnishing combine two processes: skiving, which involves removing material using a cutting tool, and roller burnishing, which smooths the surface using a set of rollers. The process compresses the material, enhancing its surface finish and mechanical properties.
  • Applications: Ideal for producing high-quality surfaces in less time, often used in high-volume production settings where cost-efficiency and speed are critical.
  • Advantages:
    • Faster processing time compared to honing
    • Produces a durable, hardened surface with Ra values around 0.2 µm
    • Cost-effective for large-scale production due to lower cycle times
  • Limitations:
    •  Less effective in creating deep cross-hatch patterns for lubrication retention
    •  Lower precision in bore size control compared to honing

Tabular Comparison of Honing vs. Roller Burnishing

Feature Honing Roller Burnishing (with Skiving)
Definition Uses abrasive stones to remove material and achieve a fine finish Combines cutting and compressing of material to improve surface finish
Surface Finish Very smooth finish (Ra as low as 0.05 µm) Good finish (Ra around 0.2 µm)
Dimensional Tolerance High precision, excellent for tight tolerances Moderate precision, suitable for most industrial applications
Material Removal Removes material through abrasion Minimal material removal
Processing Speed Slower due to abrasive process Faster due to combined cutting and rolling
Cost Efficiency Higher initial costs, but excellent for critical applications Lower cost per part, ideal for high-volume production
Lubrication Retention Excellent due to cross-hatch pattern Less effective than honing
Application Hydraulic cylinders, automotive, and aerospace where superior finish is needed General industrial applications where speed and cost are critical
Equipment Cost High Moderate to low
Material Waste Higher due to abrasive removal Lower due to minimal removal
