Features of a 45° Portal-Type Band Saw Machine

1. Structural Characteristics

Portal Design: Heavy-duty gantry structure ensures high rigidity and stability, ideal for large workpieces.
45° Cutting Angle: Adjustable saw frame tilts up to 45° for bevel cutting without repositioning.
Robust Frame: Reinforced cast iron or welded steel construction minimizes vibration and ensures precision.

2. Functional Advantages

High-Efficiency Cutting: Equipped with a high-power motor and fast-cutting blade, suitable for batch processing of metal (steel, aluminum) or wood.
Automatic Feed System: Optional hydraulic or servo feeding mechanisms improve productivity.
Precise Angle Control: Digital protractor or CNC system ensures accuracy within ±0.1°.

3. Automation & Operation

CNC Option: Programmable cutting parameters (speed, feed rate, angle) for complex workpieces.
Smart Cooling System: Extends blade life and reduces thermal deformation.
Safety Features: Emergency stop, protective covers, and blade breakage detection.
