Knowledge Base
Honing & Superfinishing Guides
Educational content migrated from the previous WordPress website.
What Is Honing
Learn how honing corrects bore geometry, size, surface finish, and final surface structure using abrasive stones under controlled pressure.
Superfinishing
Review the old WordPress guide to tape and stone superfinishing, including full-surface contact, groove and plateau formation, and key advantages.
Metrology Guidelines
Surface Roughness Parameters: Understanding Ra vs Rz
In cylindrical finishing, checking a single roughness value is often insufficient to guarantee component functionality. For example, high peaks in a profile can pierce an oil barrier film, leading to rapid steel-on-steel friction.
- Ra (Arithmetical Mean Roughness): The absolute arithmetic average of profile heights and depths across the sample length. It provides a general average metric but completely masks individual severe peaks or valleys.
- Rz (Mean Roughness Depth): Calculated by taking the vertical distance from the highest peak to the lowest valley across five successive sampling lengths, then averaging them. It represents absolute peak heights, which is vital for high-pressure seals.
Typical Honing Phase Standards
| Honing Process Stage | Target Ra Range | Target Rz Range | Typical Industrial Workpiece |
|---|---|---|---|
| Rough Honing (80-120 Grit) | 0.80 µm to 1.20 µm | 4.00 µm to 6.50 µm | Hydraulic cylinder tube initial stock removal |
| Semi-Finish (180-280 Grit) | 0.25 µm to 0.45 µm | 1.20 µm to 2.20 µm | Automotive engine cylinder block liners |
| Plateau Honing (Finish) | 0.15 µm to 0.25 µm | 0.80 µm to 1.40 µm | Lubricated piston rings, heavy-duty compressors |
| Superfinishing (Oscillating) | < 0.05 µm (Mirror) | < 0.35 µm | Gudgeon pins, bearing rollers, shock struts |
Geometry Analysis
Bore Geometry Tolerances: Cylindricity, Ovality & Taper
Machining errors in internal bores are usually grouped into three distinct categories:
Ovality (Out-of-Round)
The cross-section is elliptical rather than a perfect circle. Corrected by using floating fixtures and optimizing stone pressure distribution.
Taper Error
The bore diameter gradually narrows at one end. Remedied by setting standard overtravel strokes or configuring bottom dwellings.
Barrel & Hourglass
Bore diameter expands or narrows in the middle zone. Corrected by setting short strokes and adjusting stone expansion rates.
