第171章 水力钻床
最新网址：m.ltxsdz.com
舜乡堡统械厂在堡的西北面，附近有一条叫窑子河的河流，水流也算端急，在河边不远处，王斗看到了这具庞大的水力钻床，一个木石制的简单机械，在水流的作用下，石盘便带动钻头缓缓旋转前进。
这水力钻床看上去很简单，但优点却很明显，钻磨兢管时永远不会累。而且可以保持固定的精度与质量。不象人力操作一样，因体力与精力的原因出现偏差。
依王斗估计，就这简单的水力钻床，比起人力，工作效率至少提高几倍，一个工匠还可以同时照看几台钻床。如果以后有机会改进，或许一台水力钻床的效率更可以提高十几倍。
当然，这种水力钻床也是有缺点的，便是成本较高，操作时也经常需要更换钻头，王斗估计，这水力钻床成本与工作效率是一对一，不过王斗看来这还是值得的。
比起将来的大量生产枪械，这些成本是王斗可以承受的。
而且依王斗目前的情况，对火饶的需求量庞大，舜乡堡工匠也是缺乏。机械的推广，并不会出现抢夺工匠饭碗的问题。这其实也是影响古时机械推广的最根本原因。
看着这庞大的水力钻床，王斗赞叹不己，他问道：“李管事，用这钻床钻取镝管，几日可钻取一根锁，管？”
李茂森略略估计了一下，道：“回大人，往日用人力钻取镝管，需要近月时日，而用这种水力钻床，六日之内，便可钻取镝管一根！”
大明的火饶通常为八棱型，侥体一头粗一头细，粗的做镝腹，细的做镜口，火镝初制时还是粗胚，铿内粗糙不平，这样的火统，自然不能作战，便需用钻头将镜铿钻大钻光。钻铿技艺较精，人办也有限，在大明，好的钻头与挫刀都是采用上好的堕子钢，堕子钢己经算是当时上等的硬钢，但其实钢性与后世还是相差甚远，用堕子钢钻镝膛，还是很难钻，一个月才能钻光也可以理解。
而且镝膛钻好不就完了，还需用四棱的钢条将铿内舌光刮净，又制作螺丝后门等，所以当时打制一门鸟镝通常需要很长的时间，需要大量的熟练工人与设备，产量还不会很高。大部分时间便是消耗在这侥管的钻铿上。
其实当时大明工匠中己经普遍使用一种人力钻床，便是用木料做框架。用圆形石盘做惯性轮，系上皮条后用人力拉动，使石盘带动钻头旋转钻膛，这种钻床比光使用人力进步不少，但还是很累，改进成水力后。便如虎添翼了。
王斗眼前的水力钻床，便是这种人力钻床的改进版，钻膛速度飞快地提高到六天一根，这效率的的提高可说是非常显著了。
听了李茂森的话，王斗也是吃了一惊：“六天一根？”
他在这水力钻床的周边走了几个来回。就这简单的机械，可以六天钻取统管一根？
王斗身后的林道符等人都是议论不己，纪小娘子也是好奇地对这水力钻床左看右看。

游龙在天燃书友，我这里三天两头停电。你不停电的地方是无法想象的。唉，祸不单行，房间内的大灯又烧了，点着一个小台灯黑茫茫的。坐在电脑前头晕目眩，一点状态也没有，今天就写这点了，改日补上吧。
