(Summary description)Rail Grinder Electric Rail Grinder Internal Combustion Rail Grinder Electric Rail Grinder Internal Combustion Rail Grinder Features: The NGM-4.8 Internal Combustion Rail Grinder is designed to polish the burrs generated by aluminum heat seamless welding or reinforced welding of rails, as well as rail wear. The body is welded with high-quality carbon structural steel plates, equipped with biased anti slip guide wheels, which can polish the two sides and top surface of the rail head, It is a specialized equipment for rail head grinding in railway engineering.

Technical parameters of internal combustion rail grinding machine:
1. Internal combustion engine power: 6.5PS (4.8kW)
2. Spindle speed: 4100r/min
3. Grinding wheel specifications: φ one hundred and fifty × sixty-five ×φ fifty-five
4. Grinding head stroke: 90mm
5. Grinding head inclination angle: 90 °
6. Profile gauge: ≥ 1000mm
7. Track width: 1450mm
8. Overall weight: 90kg
Rail grinding machine function: The rail grinding machine has a simple structure, small volume, light weight, convenient use, fast up and down tracks, insulated running wheels, safe and reliable, and is suitable for grinding the plane, side, curved surface, and various angles of the steel rail. It is also suitable for welding steel rail joints and polishing various switch rails and turnouts. This machine uses an internal combustion engine (electric motor) as the power source, suitable for on-site operations without power supply.
Main technical parameters of electric rail grinding machine

2. Overall size: 1000 × five hundred and thirty-five × 500 (mm)
3. Grinding wheel size: Φ two hundred ×Φ thirty-two × 25 (mm)
4. Vertical stroke: 0-150mm, lateral stroke: 0-50mm
5. Overall weight: ≤ 42kg
6. Suitable for various rail types (18-43-75)
The main structure and working principle of the internal combustion rail grinding machine:
The GM-4 grinding machine is powered by a GX160 gasoline engine and uses an A-type V-belt (with an inner circumference of 889mm) to drive the grinding wheel through the transmission system for rail grinding operations. The machine is mainly composed of main components such as a frame, transmission system, grinding wheel, arc grinding roller, and running device. The frame is welded with thin steel plate angle steel. The grinding wheel relies on screw and nut spiral feed, and the running device is connected to the frame with bolts. The rim of the running wheel is high, and it can also be pushed on the ground after getting off the track. Insulated wheels (or rollers) can be used for grinding the top and side of the steel rail; The roller used for grinding the top arc of the rail can be used to repair the rounded corners of the rail.
