[0027] Example 1

[0028] like Figure 1-4 As shown, a surface micro-profile adjustable tool provided by the utility model comprises: a tool body 1, a first rough forming blade 21, a second rough forming blade 22 and an adjustable structure 10, wherein the first rough forming blade 21 and the second rough forming blade 22 are mounted at the end of the tool body 1 and are centrally symmetrical, and the adjustable structure 10 comprises a locking mechanism 3, an adjusting mechanism 4 and a fine forming blade 9, wherein the fine forming blade 9 is arranged between the first rough forming blade 21 and the second rough forming blade 22, and the fine forming blade 9 is movably mounted on the tool body 1 through the cooperation of the adjusting mechanism 4 and the locking mechanism 3, and an adjustable width adjustment slot 6 is formed between the adjustable structure 10 and the tool body 1. The machining allowance can be adjusted by the adjusting mechanism 4, and the former can be fixed by the locking mechanism 3 to prevent the blade position from moving during machining.

[0029] The tool body 1 is an integrated tool. A plurality of cooling water outlet holes 5 are formed inside the tool body 1, and the cooling water outlet holes 5 extend to the first rough forming blade 21, the second rough forming blade 22 and the fine forming blade 9 respectively.

[0030] The locking mechanism 3 is arranged on an end of the adjustable structure 10 away from the tip of the precision-formed blade 9 , and the adjustable structure 10 is fastened to the tool body 1 via the locking mechanism 3 .
