The invention discloses a high-precision profile modeling grinding technology. According to the high-precision profile modeling grinding technology, a steel rail section curve is used for carrying out synchronous amplification to form a running track of a control motor and a running track of a grinding wheel, a steel rail face is compared with a weld joint, and therefore the grinding precision of the grinding wheel is precisely controlled, and a steel rail body is not damaged. Especially, two synchronous running tracks, namely, a grinding wheel moving control guide groove and a motor motion fixed tooth channel, are arranged on a saddle-shaped fixed backer, and the grinding wheel of a grinding machine is controlled to carry out grinding only along the tracks. A motor fixed round guide rod penetrates through a motor moving round guide groove to control the motor to vertically move, and the grinding wheel is made to precisely grind the arc face of a steel rail with a fixed distance always. The grinding technology is high in precision, the profile modeling effect is vivid, and the grinding machine can be dismounted to move, and is light and convenient to carry. The phenomena that the grinding precision of other steel rail grinding machines is insufficient, and produced rail faces protrude and are concave are avoided. The problem that the other grinding machines are large in size, heavy and hard to control is solved, and the grinding machine is ideal high-simulation steel rail grinding equipment.
