Band saws for sawing steel bars in bundles at construction sites

1. Core purchasing parameters

Cutting capacity:

Diameter range: Select according to the steel bar specifications (common Φ200-400mm).

Material hardness: Confirm that the equipment supports high-strength steel bars such as HRB500/600.

Automation level:

Manual: Suitable for temporary sites (low price but slow efficiency).

CNC: Error ≤±0.5mm during batch cutting, which can save 30% of working hours.

Key components:

Saw blade: M42 carbide teeth are preferred (life is 3 times longer than ordinary teeth).

Hydraulic system: Check pressure stability (recommended ≥5MPa).

Safety configuration:

Essential: emergency brake, protective cover, overload protection.

Upgrade option: laser positioning anti-collision system.

2. Use optimization suggestions

Sawing tips:

Bundling density: The steel bars need to be evenly arranged to avoid saw blade deflection.

Coolant: Always use water-based cutting fluid (reduce saw blade wear by more than 50%).

Maintenance points:

Check the guide rail lubrication daily and replace the hydraulic oil every quarter.

The saw blade tension is recommended to be controlled at 300-400N/mm².

3. Brand and model recommendation

Model: HEMU CL-250G (with automatic feeding function)

Features: semi-automatic hydraulic control, cutting range Φ250mm, suitable for cutting steel bar bundles below HRB400.

Advantages: Affordable price, simple maintenance, suitable for construction sites with limited budgets.
