正文 第3章车刀(第1页/共3页)

刘忠没想到吃面这招居然没有,早上的在拉面店里,刘忠可是听赵小匠说他是第一次去吃那家店的拉面,刘忠见赵小匠吃面很享受的样子不像有假,可这会居然拒绝了吃拉面,还说要吃自己包里的馒头,最可笑的是还说要去补习英语,就赵小匠这傻样,还去补习什么英文啊,可惜了这身的力气了。刘忠现在也是无可奈何,来硬的想都别想,来软的骗吧,赵小匠又不吃这一套。刘忠只得利用这一个半小时搬工件,要不一会赵小匠真的走了,就只剩下他一个人了。

在刘忠的指引下,赵小匠很快就用液压叉车把一托盘的工件拉到一台CA6140普车前。赵小匠没想到刘忠一身的肥肉,力气还不小,只见刘忠抱起50来斤工件麻利地塞到普车的三爪卡盘里,快速用扳手把工件固定,调整了一下车床的转数,换了一下刀架上的车刀就开始干活了。

赵小匠因为想着要忙着去赶公交车,也没停留,拖着液压叉车又去搬第二次了,听着从背后传来的哧哧声,工件被车刀削去表面的氧化皮,这声音让赵小匠记起了他小时候他第一去江机厂的车间,看到的第一个机床便是这台沈机厂CA6140,在白色冷却液的冲溅下,车刀把工件表面一层一层的削掉,露出银白色工件。又仔细听了一下,刘忠因为是在开粗,工件表面的氧化层又硬又不平,赵小匠听出哧哧声中有卡顿和不流畅,赵小匠判断不是车刀选错了,就是车刀钝了。

江机厂全称是江北机械厂,主要是生产发动机的,在90代前技术在国内实力还是相当雄厚的,只是后来厂里管理跟不上时代的发展,设备落后,慢慢地产品就没竞争力了,厂子就没落了。

CA6140卧式车床源于国内50年代自行研发的C620-1车床,C620-1车床的技术主要是从熊国引进的。CA6140卧式车床于70年代初研制成功,由于其出色的性能多次获奖,并在该类型的车床中奠定了其霸主地位,这种机床一直在生产,甚至后世普车的的命名都是延续CA6140卧式车床,比如机床命名中C代表车床,A代表结构,6代表卧式,1代表基本型号,40代表最大回转直接。

听着车床切削的声音,赵小匠又回忆起当年爷爷给他说的话,“小匠啊,这车床是机械加工的的基础,车床还是机床之母,后面才衍生出来钻床,铣床等机床。车床全是手上功夫,多练就是唯一的诀窍,其中这听声观屑就是其中的基础……”

赵小匠突然有了一点伤感,他7岁开始跟爷爷用锉刀,10岁就学了车床,可直到他高毕业也没学出个样来。心里有事,但不影响赵小匠干活,来到货车边上,又卸了十来个工件,堆了一托盘,忙活了一阵再次拉到了刘忠面前。

赵小匠多少还是受了一点触景生情的影响,饶是他生性豁达,可总感觉自己学十年都没让爷爷满意,没办法把自家的手艺传下去,是一件多么让爷爷失望的事,赵小匠心里在抱怨,“都怪自己的身体不争气,一做高精度的工件身体就吃不消!”
