Working Principle & Operation

The Rail Cutting Saw applies the toothless saw principle. Its thin-film grinding wheel swings back and forth along the rail axis, reducing friction and extending wheel life while ensuring a smooth cut.

Operation Steps: Install the grinding wheel, confirm phase sequence, idle motor for 30 seconds, clamp rail securely, and swing lever evenly. Cutting sequence: top of rail → waist → bottom.

Usage & Maintenance

Check grinding wheel for cracks before use.
Do not over-tighten lock nuts.
Use rhythmic lever swings and machine's self-weight for cutting.
Follow proper cutting sequence for maximum efficiency and safety.

Applications

The Rail Cutting Saw is essential for railway track maintenance departments, major line overhauls, and emergency repairs. It guarantees precise cuts, operational efficiency, and compliance with railway standards.
