我厂的刀杆原采用锻造毛坯然后一切削加工,生产率低,浪费原材料。为适应生产的发展,我俏采用精密铸造制造刀杆毛坯,解决了生产刀杆紧张的矛盾。技术经济指标如下: 1.材料利用率达75粥(我厂全部利用废钢)。 2.全年可为国家节约钢材加吨。 3.节约机械加工工时50拓以上。 4.生产率提高1~2倍、 5.成本下降20书 I used the original factory forging the blank holder forging and then a cutting, low productivity, waste of raw materials. In order to adapt to the development of production, I am pretty about using precision casting manufacturing blank holder, to solve the production of arbor tension tension. Technical and economic indicators are as follows: 1. Material utilization of 75 porridge (I use all the scrap plant). 2. Throughout the year for the country to save steel plus tons. 3. Saving more than 50 processing hours of mechanical processing. 4. Productivity increased by 1 to 2 times, 5. Cost reduction of 20 books
