从毛坯到加工成气缸套成品实例范围。 被加工材料:灰铸铁,硬度HB200～260 流水作业线:见上简图 生产率:当利用率为80%时,每小时60 件(同时加工两个另件) 单件工时:0.8分 工作循环:自动循环 作业顺序: 1.粗加工内孔、加工两端面、粗加工外国及仿形加工外园。 2.半精加工内孔和端面,切沟槽,精镗孔(在两个位置上),测量内孔,精加工端面和外园。
From the rough to processed into cylinder liner finished product range of examples. Material to be machined: Gray cast iron, Hardness HB200 ~ 260 Flow line: See the sketch below. Productivity: 60 pieces per hour at 80% utilization (two pieces are machined at the same time) Single piece working time: 0.8 minutes Working cycle: Automatic cycle job sequence: 1. Rough machining of the hole, the processing of both ends, rough machining of foreign and contoured garden. 2. Semi-finish the bore and end face, cut the groove, fine boring (in two positions), measuring bore, finishing face and outer garden.
