我厂细纱机产品零件8211后上罗拉工字架(参阅图一),原系在牛头刨床上刨两侧面。当时质量如按照每工250只计算,则必需添置牛头刨。1953年由金工车间技术员张义芳同志建议,将他厂调拨来的机床添制部份零件,改装成为目前所使用的转盘铣(见图二)。转盘上共装10只夹具,每只夹具上装夹二只工字架,一面靠山高,一面靠山低,这样在铣好一面后可翻过来再铣另外一面,产量达每工600只,较原来提高140%,劳动强度反较在牛头刨上加工为低。因转盘不停地旋转,操作者只需装拆工件而已。转盘旋转很慢,有充分的时间进行装拆。转盘系垂直装置,操作者或坐或站立于铁屑飞出的相反一面。铁屑
After my factory spinning frame parts 8211 on the roller frame (see Figure I), the original Department of shaper planing on both sides. At that time, if the quality is calculated on the basis of 250 pieces per work, it is necessary to purchase a bulldozer. In 1953, Comrade Zhang Yifang, a technician of a metalworking workshop, suggested that some of the machine parts transferred from his factory should be rebuilt into the currently used turntable milling machine (see Figure 2). A total of 10 fixtures on the turntable, each fixture on the folder two I-frame, one side of the mountain high, low on the side of the back, so milling a good side can turn over and then milling the other side, the output of 600 per work, compared with the original Increased by 140%, labor intensity compared to the processing on the bulldozer is low. Due to the constant rotation of the turntable, the operator only needs to attach and detach the workpiece. Turntable rotation is slow, there is sufficient time for assembly and disassembly. The turntable is a vertical device, the operator sitting or standing on the opposite side of the iron filings. Iron filings
