Rail Cutting Machine
Send Enquire Now
A rail cutting machine is an indispensable piece of track maintenance equipment in modern railway construction, maintenance, and emergency repair operations. Also known as a rail cutting saw or abrasive wheel-type rail cutter, it employs a toothless sawing principle, driving a high-speed rotating abrasive wheel to cut the rail through an oscillating motion along a specific trajectory. It features fast cutting speed, high precision, and excellent cut surface quality, meeting the cutting needs of rails of various specifications.
Depending on the power source, rail cutting machines can be classified into internal combustion, electric, hydraulic, and lithium battery types, among others. They are suitable for various scenarios such as ordinary railways, high-speed railways, subways, municipal rail transit, and industrial tracks, and are widely used in track laying, rail replacement, damaged section removal, length adjustment, and emergency repairs. Their cutting efficiency and quality directly affect the progress of railway projects and the safety and stability of line operations.
