砂轮机的安全操作 | 2012-7-5 7:52:00

(1) 砂轮机应安装在僻静安全的地方,旋转方向禁止对着通道,启动前,应先检查机械各部螺丝、砂轮夹板、砂轮防护罩、砂轮表面有无裂纹破损等,确认完整良好再启动。 

(2) 工件的托架必须安装牢固,托架面要平整,托架的位置与砂轮架的间隙不得大于3mm,夹持砂轮的法兰盘直径不得小于砂轮直径的1/3,夹力适中。对有平衡块的法兰盘,应在装好砂轮后,先进行平衡测试,合格后方能使用。 

(3) 砂轮要保持干燥,防止受潮而降低强度。 

(4) 砂轮轴头紧固螺丝的转向,应与主轴旋转方向相反,以保持紧固。砂轮起动须达到正常转速后,方准进行磨件。 

(5) 严禁两人同时使用一个砂轮打磨工件。 

(6) 砂轮不圆、厚度不够或者砂轮露出夹板不足25mm时,均应更换新砂轮。 

(7) 磨工件时,不准振动砂轮或打磨露出中易发生振动的工件。 

(8) 砂轮只准磨钢、铁等黑色金属,不准磨软质有色金属或非金属。 

(9) 砂轮禁装倒顺开关,路途停电时,应立即切断电源。 

(10) 磨工件时,应使工件缓慢接近砂轮,不准用力过猛或冲击,更不准用身体顶着工件在砂轮下面或侧面磨件。 

(11) 磨小工件时,不应直接用手持工件打磨,应选用合适的夹具夹稳工件进行操作。 

(12) 安装砂轮片时,不准用铁锤进行敲击。如孔大于轴径,应加套筒不得有空隙,轴端须有两个以上的螺母紧固。根据旋转方向来用正、反旋转螺纹。 

(13) 砂轮机转轴发生弯曲后,应立即停用,更换新部件后方可继续使用。
