The NGM-4.8I is a digital display rail grinding machine powered by a GX200 internal combustion engine rated at 4.8 kW and over 3600 rpm. It is designed for precision grinding of 43 kg/m to 75 kg/m rail sections, targeting weld joints, uneven surfaces, fat edges and repair welding on rail heads. The machine’s grinding wheel operates at a linear velocity exceeding 35 m/s, with spindle rotation at 4500 rpm, enabling efficient material removal.
Constructed with a stainless steel frame, the NGM-4.8I measures 1500 mm in length, 450 mm in width and 750 mm in height, weighing 90 kg for portability on track maintenance sites. The grinding wheel specification is 125 mm x 65 mm with an M20 bore, while the profile wheelbase is fixed at 1000 mm for consistent rail profiling. Inclination angles for the grinding wheel range from +90 degrees, with accuracy settings of 0.5 to 5.0 degrees in 0.5-degree increments.
This machine is used by railway maintenance crews and track infrastructure providers to restore rail surface geometry and remove defects that could compromise safety or ride quality. The digital display allows operators to set precise grinding parameters, including stroke length (45 mm) and feed accuracy (0.05 mm to 0.3 mm). Buyers should confirm fuel type compatibility for the GX200 engine and ensure the machine meets their rail profile standards.

Before placing an order, verify that the NGM-4.8I’s rail profile compatibility (43 kg/m to 75 kg/m) matches your track specifications. Confirm the fuel type for the GX200 engine, as this may impact operational costs and availability in your region. Additionally, request documentation on the machine’s compliance with railway industry standards for safety and performance.
Clarify logistics details such as lead time, packaging and Incoterms, as these are not specified in the listing. The supplier’s harbor trust tier suggests baseline verification, but buyers should negotiate shipping terms (e.g., FOB Wuhan) and confirm whether the machine is delivered with necessary accessories like grinding wheels and toolkits. Payment terms should also be agreed upon directly with Wuhan Linkage Track Equipment Co.,ltd.
For quality assurance, inspect the machine upon delivery for build quality, particularly the stainless steel frame and grinding wheel assembly. Test the digital display’s accuracy for inclination angles and feed settings, and ensure the engine meets its rated power output. Request a demonstration or trial run if possible, and confirm the availability of spare parts and after-sales support for long-term maintenance.
