With the reactivation of the fire saw blade sharpening process in the heavy machining unit of Jahan Foulad Gharb Company (Shokri Industrial Group), an effective step has been taken towards improving productivity, reducing costs, and strengthening technical independence.
Mehdi AbdolMohammadi, Head of the Heavy Machining Unit at Jahan Foulad Gharb, who has been working at Shokri Industrial Group since 2019, successfully reactivated the fire saw blade sharpening machine by relying on his technical knowledge and field experience—a process that had previously been fully outsourced to external companies.
The specialized fire saw blade sharpening process consists of five key stages:
Comprehensive inspection of the blade for cracks, dullness, or physical damage
Precise adjustment of tooth angles according to the type of saw and the material being cut
Correction of bends and geometric straightening of teeth
Accurate sharpening of cutting edges using an industrial stone or file
Final inspection and application of finishing adjustments
This process increases tool lifespan, reduces machine strain, improves cutting precision and quality, and decreases production line downtime.
At Jahan Foulad Gharb, two types of fire saw blades are used:
✓ Cold-Cutting: Suitable for cutting low-heat materials with light alloy structures
✓ Hot-Cutting: Designed for cutting high-temperature materials requiring stronger alloys
Signs indicating the need for re-sharpening include reduced cutting speed and accuracy, increased blade temperature, abnormal chip formation, and tooth-edge fractures.
AbdolMohammadi emphasized the role of this initiative in strengthening the technical resilience of the complex, noting: “Adherence to safety standards, high precision in adjustments, and the use of specialized tools are the three vital elements in the successful execution of this operation.” With the revival of this process, not only has production quality improved, but reliance on external services has also been minimized.
