第173章 四轴铣床(1 / 2)

有了图纸只是第一步,接下来的零件加工才是重点。

最先试制的是燃气轮机的压气机叶片,由于产品外形是曲面所以此时一般的加工方法是仿形车床和电化学化加工。

仿形车床主要是成形加工,原理跟配钥匙有点像,就是必须要有一个模板,而且加工精度主要由模板的精度决定,就跟之前的晒图一样得先人工加工一块底片,然后才能批量生产产品。

不过仿形车床缺点跟晒图一样,要先得到模板,对于批量生产的产品要进行修改升级相当的麻烦。

既然是人工加工就有极限,而且培养这样一名工人需要几十年的时间,工人能力成形前是需要大量的学习和训练。

此时在实验室的所有人都把目光集中在了,一台四轴铣床上了。

“长空,你开发的这个机床除了x轴,y轴和z轴连同外,这个工作台上的分度器也可以联动!”当机床开起来时,喻娟吓了一跳。

“是的,实现了4轴联动之后,压气机叶片加工就可以不用先做模板直接进行加工。”苏长空道。

“好,好,好,长空你这可是解决了目前生产中的难题,要是有了这个四轴联动的铣床,涡喷8的改型生产至少能提高5倍的效率不止。”喻娟惊道。

“5倍!妈没这么夸张吧!”袁富贵也吓了一跳。

“5倍还是一个赶时间上的好处,除此之外,对于发动机的升级可是有绝对定性作用的?”喻娟此时已经在想,

“这事得赶紧回去向汤厂长汇报,如果有可能直接将正在试制的涡喷8压气机叶片送到1199厂来加工?”

“长空,这机床真有这么厉害!”袁富贵见自己母亲在思考问题,也不好打扰,于是就向苏长空打听了起来。

“你忘了,上次在秦川航空发动机厂给他们做仿形机床的模板了?”苏长空边说边盯着电脑屏幕,观察机床反馈的实时检测数据与理论计算数据的对比。

早期的数控机床虽然实现了按照理论计算的刀具轨迹运动,可是机床在自检方面却很弱,也就造成了不能对误差进行补尝,这就造成了机床加工的精度不好控制,而真正的数控机床就可以根据实时的测量数据对误差进行实时补尝,从而使精度一直保持下去。

“对啊,我可听那些做模板的师傅说了,一块手工加工的模板至少要5天时间,而且还不一定能成功!”袁富贵一想到这,也就不说话,他要看看眼前加工的这块叶片到底能节约多少时间。

时间就这样一分一秒地过去,还没等第一块叶片加工完,接到消息的汤厂长已经带着一群人火急火燎地跑过来了,早已经在实验室门口等候的喻娟赶紧向汤厂长汇报了情况。
