ABSTRACT:
A method for manufacturing a rail for use in a linear motion rolling contact guide unit is provided. A rail intermediate product having a top surface, a pair of side surfaces, each formed with a guide groove portion, and a bottom surface is provided by drawing from an alloy steel material. Then the guide groove portion is hardened by induction hardening. The side surface is then ground by a profiled grinder having a grinding shape complementary to the shape of a side surface of a finished rail.
