目前我国生产的以压缩空气为动力的砂轮机,品种和规格虽多,但多为手持式的。近年我们制造了一种安装在工作台上,固定使用的台式气动砂轮机。砂轮机具有体积小、使用安装方便、适合在经常移动位置的情况下使用等特点并可根据需要调整砂轮机的转速;砂轮机在运转时因超负荷造成停转也不会损坏机件。气动砂轮机适合磨一些较小的刀具,如自动车床用的车刀及台钻用的钻头,其结构如下: At present, China’s production of compressed air powered grinder, although the variety and size, but mostly handheld. In recent years, we have manufactured a bench-mounted pneumatic grinder mounted on a workbench for fixed use. Grinder with small size, easy to use and install, suitable for use in the case of frequent movement and other characteristics and can be adjusted according to the needs of the grinder speed; grinder in operation due to overload caused stall will not damage the mechanical parts. Pneumatic grinder suitable for grinding smaller tools, such as automatic lathe turning tools and drill bits used, the structure is as follows:
