凿岩机械与风动工具广泛用于冶金、煤炭、水电、化工、建筑工程、机械制造、农田水利及国防等有关部门。是实现机械化生产不可缺少的重要机具。在采矿工业中,不论是露天的剥离和回采,还是井下的开拓、采准和回采,都必须经过凿岩工序。目前,在钻凿硬岩炮孔时,几乎全部采用风动凿岩机械。在汽车、拖拉机、柴油机、机车车辆、 Drilling machinery and pneumatic tools are widely used in metallurgy, coal, hydropower, chemical, construction, machinery manufacturing, irrigation and water conservancy and other relevant departments. Is an important tool to achieve mechanized production is indispensable. In the mining industry, both in the open-air stripping and recovery, or underground exploration, mining and mining, must go through drilling process. At present, when drilling hard rock hole, almost all the use of pneumatic rock drilling machine. In the car, tractor, diesel engine, rolling stock,
