矿山机械设备的检修,需要大量的备品备件,特别是像凿岩机这样的常用设备,备件容易磨损,消耗量更大,因此,凿岩机备件往往供不应求,影响矿山生产。怎样解决这个问题呢?吉林冶金机械修造厂冲破锻造能力不足的困难,用精密铸造法生产凿岩机备件,给我们指出了一个多快好省地解决备品备件问题的好办法。这个厂自一九七○年起,自力更生,由土到洋,生产了精铸凿岩机备件。三年来,产量
Maintenance of mining machinery and equipment, requires a large number of spare parts, especially common equipment such as rock drill, spare parts are easy to wear and tear, greater consumption, therefore, rock drill spare parts are often in short supply, affecting mine production. How to solve this problem? Jilin Metallurgical Machinery Repair Factory to break the forging capacity of the lack of difficulties, the use of precision casting method to produce rock drill spare parts, give us pointed out that a more efficient and cost-effective solution to spare parts problem. Since 1970, the factory has been relying on its own efforts to produce spare parts for the foundry rock drills from earth to ocean. Three years, production
