Introduction
This report provides an in-depth analysis of quality performance for INOX 140 and INOX 140 Thin blades across INOX 220 and INOX 360 machines. Using a quality scoring system (0.75 = rough cut, 3.0 = clean cut with no burrs), we compare configurations by wall thickness.
Results show that INOX 140 Thin generally achieves higher quality scores and reduces severe burrs, while INOX 220 consistently supports better finishing compared to INOX 360.
Methodology
Tests were conducted on inox pipes with wall thicknesses ranging from 1.6 mm to 4.0 mm. Two machines (INOX 220 and INOX 360) and two blade types (INOX 140 and INOX 140 Thin) were evaluated under different speed settings (I and II). Quality was assessed based on cut appearance and burr level, converted into a numeric score for comparison.
Results
Figure 1 illustrates average quality scores by wall thickness, machine, and blade. Higher scores indicate cleaner cuts with fewer burrs. INOX 220 combined with INOX 140 Thin consistently ranks highest, especially for thin and medium walls (≤ 3mm).
Figure 2 below shows burr distribution by blade type. INOX 140 Thin significantly reduces heavy burr compared to INOX 140, shifting most cases to “some burrs” that require minimal post-processing.
Recommendations
- Use INOX 140 Thin when burr reduction and finishing quality are critical.
- Prefer INOX 220 for operations requiring high-quality cuts when the pipe OD matches the machine OD range.
- For thicker pipe walls (4.0 mm), use INOX 140 blade and consider process optimization to maintain quality.
Conclusion
The analysis confirms that the blade selection and the machine choice significantly impact cut quality.
INOX 140 Thin offers a measurable advantage in reducing severe burrs, while INOX 220 provides consistently better results across most thicknesses. Implementing these recommendations will improve product quality and reduce post-processing time.
