Detailed
Overview
The Rail Grinder RCG-L65 is a new-generation lithium battery numerical control rail grinder evolved from the NGM-6.3 II platform. It replaces the internal combustion engine with a 5.0 kW DC brushless motor and 72V-20Ah lithium battery, eliminating noise, vibration, and exhaust emissions—ideal for urban transit, tunnels, and depots.
It inherits the intelligent copying mechanism but enhances efficiency through digital feed control. The machine achieves high copying accuracy and polishing efficiency, with grinding wheel stroke of 59 mm, profile track of 1010 mm, and feed accuracy of 0.01–0.5 mm.
Weighing only 62 kg (without battery) and operating within –40°C to +70°C, the RCG-L65 offers long runtime (6 aluminum welds per charge) and IP45 protection. It’s the smart, sustainable choice for modern rail infrastructure teams.
Key Features
⚪ 72V Lithium-Powered DC Control System: Integrated with comprehensive safety protections against overcurrent, overvoltage, undervoltage, and overtemperature.
⚪ Multi-Function Versatility: A single machine supports various grinding applications through the use of different accessories.
⚪ Intelligent Electric Control: Features two adjustable grinding speeds – low speed for rough grinding and high speed for fine finishing.
⚪ Dual Operating Systems: Supports both manual handwheel feed and electronic feed for flexible operation.
⚪ Lithium Battery Power Source: Provides low-noise, low-emission operation, capable of functioning in diverse environments including high altitudes, rain, and extreme cold (e.g., -30°C).
⚪ Superior Endurance: A single charge supports grinding at least 6 thermite welds or 8 laser welds.
