The invention discloses a seamless steel tube with a latticed inner surface and a lattice pressing method thereof. The inner surface of the seamless steel tube is latticed, the latticed inner surface is formed by grooves and lattices distributed evenly and densely, the grooves are parallel or crossed, and the lattices are arranged among the crossed grooves. A hole boring process and production processes before the hole boring process of the seamless steel tube are the same as those of a conventional seamless steel tube; left-hand slots are formed in the inner surface of the perforated and rolled steel tube in a pressed mode through a bucket type two-roll cross-rolling piercer; the rolled steel tube with the pressed left-hand slots enters the other bucket type two-roll cross-rolling piercer, and right-hand slots are formed in the inner surface of the rolled steel tube in a pressed mode; latticed texture structures are formed on the inner surface of the rolled steel tube which is pressed twice. The seamless steel tube with the latticed inner surface is obtained through the lattice pressing method, so that the inner surface of the seamless steel tube has good lubricating property and surface supporting property, and use performance of the seamless steel tube is improved.
