Differences in Quality of Wood Veneer Rotary Cutting Knives from Different Manufacturers
1.Raw Materials
High-end brand: Japan Kanefusa. All its raw materials are imported Japanese steel, and the factory is located in Indonesia.Manufacturers adopt different steel grades. Large factories purchase rawmaterials in bulk from steel mills, with stable material composition and consistent quality.Knives from small factories use raw materials sourced from small steel mills, where the quality and composition of each batch are unstable and contain impurities, resulting in inconsistent product quality per batch.
2.Production Process
Our large-scale factory has more sophisticated and complete production procedures and has gone through multiple processing technologies.

3.Equipment
Kanefusa (Japan) uses high-precision Japanese grinding machines. Thanks to their high accuracy, the knives produced have better precision and quality.
4.Hardness Treatment (Quenching)
Kanefusa's heat treatment furnaces can control hardness within a tolerance of ±0.5 HRC, while most domestic factories can only reach ±1 HRC. Other small manufacturers are not capable of this level of hardness treatment.
5.Edge Sharpness Retention
Large factories use special edge treatment technology, allowing the blade to stay sharp during long-term use and reduce re-grinding frequency.Small
factories use simple edge processing, so blades become dull easily during operation, which affects efficiency and quality.
6.Dimensional Accuracy
Large factories use high-precision equipment and strict dimensional inspection, ensuring extremely small dimensional errors for each rotary knife.Small
factories have limited equipment accuracy, resulting in larger errors that may cause fitting problems during installation and use.
7.Corrosion Resistance
Large factories apply special coating on the blade surface to improve corrosion resistance, effectively preventing rust even in humid and harsh
environments.Small factories often skip or simplify this step, so blades rust easily and have a shorter service life.
8.Cutting Quality & Stability
Knives made by large factories have uniform material and refined
craftsmanship, with low vibration during high-speed cutting, providing a
smoother and flatter cutting surface.Knives from small factories vary in quality, causing vibration/chatter during cutting and leading to rough surfaces.
9.Quality Management & Consistency
Large factories have a complete production management system, ensuring highly consistent quality for every batch.Small factories are limited by
technology and management, with large quality differences between batches, meaning you may need to re-adjust for each order.
