不管是对于除去钢轨表面缺陷还是保持钢轨合适的外形轮廓、保证行车稳定性来说，钢轨打磨都是经济和实用的技术。
Rail grinding is a practical and economical technique for not only removing surface defects but also maintaining favorable rail profiles.
特别有效的是将钢轨的断面廓形打磨成满足系统要求的形状。
Rail profile grinding can be particularly effective if the applied profiles are tuned to the specific system requirements.
与之对应，直线段的钢轨通常打磨成与车轮有几点接触的形状，车轮与轨道之间是非共形接触，从而减少轮对不正常的摆动。
Tangent track, on the other hand, may be ground to several contact points to promote non-conformal contact and thus reduce wheelset hunting.
该技术生效的前提是钢轨断面在确定的公差范围之内并在打磨前未被损坏。
A prerequisite for the effectiveness of the technology is that the rail profile is within defined tolerances and undamaged before the grinding.
打磨机拉动专用磨石倾斜地经过钢轨，带动它们被动旋转。
The grinding machine pulls special grinding stones over the rails at an Angle, causing them to rotate passively.
发动机带动小带轮转动，通过皮带传动带动磨头旋转，对钢轨产生打磨作用；
Engine drives the pulley to rotate, and the grinding head is driven to rotate by the driving belt to grinding the rail;
结果表明，设计的钢轨预防性打磨形面与钢轨原始形面的各项性能均相差不大，符合预期。
The results show that the design of preventive rail grinding profile is little difference with the original profile, in line with expectation.
因此，由于更换钢轨时间提前以及昂贵的维护费用，如传统的打磨、铣削或刨削都使铁路的生命周期成本大大增加。
As a consequence, rail life-cycle costs have risen considerably due to premature rail replacements or costly maintenance such as traditional grinding, milling or planing.
