Super finishing can usually be divided into three periods: cutting period, half cutting period, and finishing period.
(1) When the surface of the grindstone and the surface of the rough raceway are touched during the cutting; because the touch area is more than that of the ノ ノ 沽 沽 沽 沽 沽 螅 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔Resignation of Xing 鳌 饔茫 饔茫 ナ砻娴牟糠 ナ砻娴牟糠 チ チ チ チ 浜 浜 浜 浜 浜 浜 浜 浜 浜 浜 浜 チ チ チ チ チ チ チ チ チ チ チ 腿 腿 腿 腿 腿 腿 腿 腿 腿 腿The cutting and anti-cutting effect removes the peaks on the surface of the workpiece and grinds the enthalpy layer. This period is called the cutting period; during this period, most of the metal allowance is removed.
(2) During the half-cutting process, the machining continues; the surface of the workpiece is gradually smoothed. At this time; the touch area 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 stone surface 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 on the surface of the workpiece become shallower; and the darker luster appears.
(3) During the finishing period, this is the final period of super-finishing. The surface of the workpiece is gradually smoothed; the touch area of ​​the grindstone and the external appearance of the workpiece is further increased; and; the grindstone and the appearance of the workpiece are gradually blocked by the smooth oil film; The pressure on the unit area is very good. The patrol is allowed to circulate the gongs and the sputum is sputum. The sputum is called V-Xing. This period is called the finishing period. There is no cutting marks on the surface during the finishing period. Showing all the luster.
