K1270R Portable Rail Cutting Machine

Scope of application: The K1270R Rail Cutting Machine is a railway maintenance machine that uses an imported motive power of combustion engine. It cuts rails quickly with less wear on the grinding wheel and locks the machine by clamping the rails.
This model features a compact structure, lightweight design, and is easy to move and operate. It is suitable for railway maintenance, the repair of broken rails on seamless lines, and cutting rails in long rail welding factories. When cutting rails, the verticality tolerance of the rail cross-section can be ≤0.2mm, and the smoothness of the rail cross-section also meets the usage requirements.

QG-4 II Electric Rail Cutting Machine

QG-4 II electric rail cutting machine is suitable for cutting 43kg/m~75kg/m rails, and the cutting section quality meets the requirements of railway industry standards. It is a machine tool railway engineering departments use for line overhaul, maintenance and emergency repair operations.
It has the characteristics of fast cutting speed, high utilization rate of thin-slice grinding wheel, high quality of cutting section, simple operation, easy to move, safe use, and wide application range.
Working principle: Utilizing toothless saw cutting, a swing mechanism enables the rotating thin-slice grinding wheel axis to reciprocate along a trajectory around the rail axis, allowing the thin-slice grinding wheel to cut the rail. The contact length between the rotating plane of the thin-slice grinding wheel and the rail section is minimal, which reduces wear on the thin-slice grinding wheel and enhances its utilization rate and work efficiency.

NQG-5III Rail Cutting Machine

NQG-5III rail cutting machine is suitable for cutting 43kg/m~75kg/m rails. The cutting section quality meets the requirements of railway industry standards and is an essential machine for railway engineering departments to carry out overhaul, maintenance and emergency repairs.

This machine features a double-swing structure, cutting time of under 2 minutes, high utilization rate of the grinding wheel, low cost, excellent cutting section quality, and user-friendly operation. It can be moved not only on land but also on rails, ensuring safety and versatility across various applications.

Rail Cutting Machine Role in Rail Track Maintenance

As a key equipment in railway maintenance and construction, rail cutting machines play an important role in the following scenarios. Their efficient and precise cutting capabilities significantly improve work efficiency and safety:

Routine rail maintenance: When local damage (such as cracks, crushing, excessive wear or joint diseases) is found in daily inspections, the damaged section needs to be cut off and replaced with a new rail.
Seamless line repair: When the seamless line (long rail) is partially deformed or broken due to temperature stress, fatigue damage or external force impact, the failed section needs to be cut off and re-welded.
Line overhaul construction: When replacing the entire section of rails, upgrading the turnouts or expanding the line, the existing rails need to be cut and removed on a large scale.
Emergency repair work: When the line is interrupted by natural disasters (floods, earthquakes), accidental collisions or sudden rail breaks, it is necessary to quickly open the line.
