Processing technology of high-precision hard alloy bar

Abstract

The invention relates to a high-precision hard alloy bar machining technology which comprises the following steps that S1, a round bar blank is obtained through the procedures of smelting, forging and rolling, then the round bar blank is subjected to annealing treatment, in the annealing treatment process, the round bar blank is clamped through clamping and rotating equipment and can be rotated, and the round bar blank is subjected to heat treatment; the laser beam emitter can be used for emitting light beams with high aggregation and high energy density, secondary small-area annealing treatment is carried out on a specific area with uneven surface temperature distribution of the round rod blank, targeted independent secondary annealing treatment can be directly carried out on the area with uneven surface annealing temperature of the round rod blank, and the annealing temperature of the round rod blank is not uniform. After all the areas with the uneven annealing temperature on the surface of the round bar blank are subjected to annealing treatment, the annealing temperature on the surface of the round bar blank can be homogenized, and therefore stress relief of the round bar blank is homogenized.
