Switch and Rail Grinding Machine - NCM‑5.1Ⅱ Digital Turnout Rail Grinder

NCM‑5.1Ⅱ Switch and Rail Grinding Machine is specialized portable gasoline‑powered grinding equipment for railway turnout maintenance. It is widely used for precision grinding of turnout point rails, frog core rails, wing rails, as well as side fat edges and curved surfaces of various steel rails. Featuring microcomputer‑controlled precise feed and angle adjustment plus integrated night lighting function, this turnout grinder delivers human‑friendly operation, high‑accuracy control, rational mechanical layout and stable reliable quality. It is essential track‑maintenance machinery for railway public‑works departments.

Working Principle & Basic Structure

Working Principle

Power is transmitted from gasoline engine through clutch and belt assembly to drive the grinding‑wheel spindle for high‑speed rotation. The built‑in microcomputer controls stepper motor to drive screw‑nut mechanism for vertical feed and grinding movement. Horizontal feed grinding is implemented manually via angle lever.

The small sub‑frame carries stepper motor and angle plate; it enables grinding‑wheel left‑right tilting over 35°, meeting diverse bevel‑grinding demands, with self‑locking devices for every adjustment angle. Operators push the large main frame for repeated longitudinal travel along the rail to complete full‑range grinding tasks. The sub‑frame is equipped with working lamp, supporting day‑and‑night all‑weather field operations.

Core Advantages of Ustyle NCM‑5.1Ⅱ Switch & Rail Grinder

Microcomputer Precision Control: Digital‑display microcomputer system controls vertical feed with 0.1 mm high‑resolution accuracy, ensures consistent grinding depth and uniform rail profile, reduces manual operation error.

Wide‑range Angle Adjustment: Grinding wheel supports ≥30° bidirectional swing and over 35° tilting angle with self‑locking mechanism; perfectly fits complex geometry of point rails, frog cores and wing rails in turnout zones.

All‑weather Night Operation: Built‑in high‑brightness working lamp, enables maintenance work during night‑time track window periods.

Independent Internal‑combustion Power Source: Four‑stroke GX270 gasoline power unit, no external power supply needed; works for remote field sections without grid power.

Ergonomic Frame Design: Split large‑small frame layout; easy pushing travel along rails, convenient on‑track / off‑track handling, suitable for narrow turnout limited spaces.

High‑quality Grinding Outcome: Removes rail side burrs, fat edges and surface defects effectively; optimizes wheel‑rail contact geometry, lowers running noise and extends rail service life.

Reliable Certified Quality: ISO9001 & CE certified, robust welded steel frame, easy‑access spare‑parts for overseas project maintenance.

Application Scope

Precision grinding for railway turnout components: point rails, frog core rails, wing rails
