气刨又称表面切割,是一种高效率的加工工具,它可代替鈚凿工作,但比鈚凿具有很多优点:(1)工作时轻便灵活,工人容易掌握;(2)生产率高;(3)工人劳动强度降低;(4)无噪声。由于上述这些优点,许多先进的工业国家早已得到广泛的使用。我厂在苏联专家的帮助下,初步掌握了气刨的制造和应用工艺。[气刨的构造] 气刨的构造和切割器一样(图1),是由手柄1,混合室2,切割氧气管3,联 Gouging, also known as surface cutting, is a highly efficient tool that replaces chiseling, but has many advantages over chiseling: (1) light and flexible at work and easy to handle by workers; (2) high productivity; 3) reduce the labor intensity of workers; (4) no noise. Because of these advantages, many advanced industrial countries have long been widely used. I plant in the Soviet Union with the help of experts, initially mastered the manufacture and application of gouging technology. [Construction of gouging] The gouging structure is the same as that of the cutter (Figure 1). It consists of handle 1, mixing chamber 2, cutting oxygen tube 3,
