我厂下料部门每年需消耗大量的高速钢锯条。过去,用钝的锯条,因无法刃磨只能报损,既造成很大浪费,还严重影响生产。为此,我们利用废旧材料革新制成一台锯条刃磨机。钝了的锯条经刃磨后,同新锯台一样好用。每年可节约上万元财富和相当数量的高速钢材料。我们制成的这台刃磨机床,它的原理同圆 I expected to consume a large number of high-speed steel hacksaw cutting unit every year. In the past, the use of blunt saw blades that failed to shatter only reported losses, causing significant waste and seriously affecting production. To this end, we use scrap material to create a blade sharpener. Blunt saw blade after sharpening, the same with the new sawing station easy to use. Each year can save tens of thousands of yuan of wealth and a considerable number of high-speed steel materials. We made this sharpening machine, its principle with the circle
