Traditional rail grinding machinery is mainly composed of main components such as a frame, a transmission system, a grinding wheel, and a traveling device. It can better polish the top and side surfaces of rails.
但是，现有钢轨打磨机械普遍存在体积、重量大，运输及操作使用不便等缺陷，致使对钢轨端面棱边倒2×45°斜面的加工，现场仍采用人工手握打磨机作业，因钢轨端面棱边呈弧状形，从而带来整个加工面尺寸误差过大，对后道工序加工带来不良影响，并且全过程劳动强度极大。However, existing rail grinding machines generally have shortcomings such as large size, weight, and inconvenience in transportation and operation. As a result, manual hand-held grinders are still used on-site to process the rail end edges with 2×45° bevels. The edges are arc-shaped, which leads to excessive dimensional errors on the entire processing surface, which has a negative impact on subsequent processing steps, and the whole process is extremely labor-intensive.
