The invention relates to a process for strengthening abrasive resistance of an internal surface of an open-end spinning frame rotor, with the purposes of effectively improving the internal surface hardness and prolonging the service life of the rotor and characteristics of convenience for operation and favorable economic performance. The technical scheme is as follows: the process for surface treatment of internal walls of the open-end spinning frame rotor comprises the following steps of: (1) machining to control the roughnesses of a glide plane and a collecting groove at Ra0.7-0.9; quenching the rotor by heating to 800-900 DEG C at the intermediate speed of 15-25 DEG C/min, keeping for 15-25min and cooling in water of 20DEG C to the ambient temperature; (3) then carrying out lower tempering treatment by heating to 220-240 DEG C at the intermediate speed of 15-25 DEG C/min, keeping for 12-18min, and then cooling in air to the ambient temperature; and (4) carrying out chemical nickel-plating ...
