The invention provides a ball milling-equal channel angular pressing and curing method for cycle treatment of pure titanium abandoned chips. The method comprises the following steps that (1) titanium chips are recovered and pretreated; (2) the titanium chips are ball-milled; (3) sheathing and packing of the ball-milled titanium chips are conducted; (4) the titanium chips after sheathing and packing are cold-compacted at room temperature; (5) the cold-compacted titanium chips are subjected to equal channel angular pressing and high temperature curing: a die is heated to 570-600 DEG C, an extruding force of 0.9-1.0 GPa is applied by an upper punch, back pressure of 0.2 GPa is applied by a lower punch, under the pressing effects of the upper punch and the lower punch, the titanium chips after sheathing and packing are fully densified for curing under the combination effect of severe strains when passing through an equal channel, the remanufactured titanium material is smoothly demolded under the pushing action of a pure aluminum pseudo sample, hole defects are eliminated thoroughly, and the equal channel is extruded repeatedly for the two times to obtain a uniform-structure fine-grained material; and (6) quenching is conducted: a block titanium material, obtained in the step of equal channel angular pressing and high temperature curing, is quenched and cooled to the room temperature in a water cooling way.
