GM-4II Electric Rail Grinding Machine
GM-4II type electric rail grinding machine is mainly used in the railroad rail maintenance construction of welded joints, calendering burrs, rail surface repair, wave abrasion and other restoration of repair and grinding operations. The machine has been greatly improved in structural arrangement, transmission mode, control mode and other aspects. Not only the profiling accuracy, grinding efficiency and other technical performance has been greatly improved, and due to the development and application of CNC feeding unit, intelligent control of grinding wheel feeding has been realized. This greatly simplifies the construction operation, measurement and other operational steps, and avoids the problem of "over grinding" during construction. The further optimized structural design of the whole machine and the humanized arrangement of the operating elements make the construction work more easy and simple, fast and efficient.
