在全民大搞钢铁运动中,我厂接受了一个批量很大的制造鼓风机的任务。大伙都感到这个任务很光荣,但也很艰巨,个个都想为完成这个任务贡献出更多的力量。于是,围绕着鼓风机的加工,在全厂内迅速地掀起了一个技术革新的高潮。鼓风机的主要零件是鼓风翼,内孔需要加工。开始时是采用单刀来加工的。由于内壁面比较深,刀杆的伸出长度比较长,刚性弱,振动大,所以使工件的精度和光洁度都不好控制,而且效率也很低。鼓风翼加工效率的高低,加工质量的好坏,对完成
In the national campaign for steel, I received a large factory volume manufacture blower mission. Everyone feels that this task is honorable, but it is also arduous. All of them want to contribute more power to accomplish this task. So, around the blower processing, quickly set off in the whole plant a technological innovation climax. The main part of the blower is the blower wing, the bore needs to be machined. The beginning is a single-pole to the processing. As the inner wall surface is relatively deep, the length of the arbor is relatively long, the rigidity is weak and the vibration is large, so the precision and the finish of the workpieces are not well controlled and the efficiency is also very low. Blast wing processing efficiency level, processing quality is good or bad, the completion
