第一条:使用硬质合金鑿岩的鑛山,应在锻钎工段下,设立钎头研磨室,专门负责本鑛山钎头的研磨工作或必要时的硬质合金工作。第二条:硬质合金钎头须在专作研磨硬质合金钎头的研磨机上研磨,如无磨钎机的设备时,可按磨钎机上的必要设备適當地改装磨床作为临时研磨钎头之用,研磨钎头用的磨床必须装有给水装置和安全罩。第三条:磨钎机或改装的磨床必须堅固地安装在混凝土的基础上,主轴必须稳定不许颠动或串动,轴承要紧密合適,皮带必须正确的安装以免发生震动。第四条:研磨硬质合金钎头必须先磨炭素钢部分后磨
Article 1: In the case of a mine using carbide rock drilling, a drill bit grinding room shall be set up under the forging section, which is responsible for the grinding work of the ore head of the mine or cemented carbide work if necessary. Article 2: Carbide drill bits shall be grinded on a grinding machine specially designed for grinding cemented carbide tips. If there is no grinding and brazing equipment, the grinding machine may be properly modified as necessary to grind the brazing head according to the necessary equipment on the grinding and brazing machine The grinding machine used to grind the bit must be equipped with a water supply and a safety cover. Article 3: The grinding machine or modified grinding machine must be firmly installed on the basis of concrete, the spindle must be stable to not allow the movement or string, the bearings should be closely fit, the belt must be properly installed to prevent vibration. Article 4: Grinding carbide bit must first grind carbon steel part after grinding
