Super-finishing can usually be divided into three periods: cutting period, half-cutting period, and finishing period. (1) When the grindstone appearance and the rough raceway appearance are touched by the peaks during the cutting; because the touch area is more Difficult to wash, 螅 谝 谝 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ナ ナ ナ ナ ナ ナ ナ 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌 鳌胬 チ 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿 ; ; ; ; ; ; ; ; ; ; ; ; ; ; During this period, most of the metal allowance is removed. (2) The machining continues with the half-cutting process; the workpiece surface is gradually smoothed. At this time; the touch surface of the grindstone and the workpiece is added; the pressure per unit area is reduced. Xing Wei burns. Xing Wei. Together; the pores of the grindstone are blocked; the grindstone is in a half-cut condition. This period is called the half-cutting period; during the half-cutting process, the cutting marks of the workpiece surface become shallow; Darker luster. (3) This is the most super finishing time during finishing During the final period, the surface of the workpiece is gradually smoothed; the touch area of ​​the grindstone and the workpiece surface is further increased; and; the grindstone and the workpiece surface are gradually blocked by the smooth oil film; the pressure per unit area is very good.ナ 瘢 瘢 瘢 髯饔 髯饔 髯饔 跣 跣 詈笄饔谧 詈笄饔谧 詈笄饔谧 这一 这一 这一 这一 这一 这一 这一 这一 这一.
