Disclosed is smooth and attractive heat treatment linear guide rail device

The utility model discloses a smooth and attractive heat treatment linear guide rail device. The linear guide rail device comprises a guide rail (1) and a sliding block (2) matched with the guide rail(1) and smooth in appearance, a guide rail mounting hole (3) is formed in the guide rail (1), a sliding block threaded hole (4) smooth in appearance is formed in the sliding block (1) smooth in appearance, and the sliding block (2) smooth in appearance is subjected to vacuum quenching heat treatment and high-temperature tempering heat treatment. Through vacuum quenching treatment, the sliding block is not oxidized, blackened and decarburized, the surface of the sliding block is kept smooth, the phenomena that the surface of the sliding block and a mounting threaded hole are oxidized, blackened and unattractive after heat treatment are avoided, through high-temperature tempering treatment, the internal stress of the sliding block is eliminated or reduced, the hydrogen embrittlement phenomenon of the sliding block
