磨削加工是用扁具以较高的线速度对工件表面进行加工的一种机械加工方法。磨削加工中的常用磨具为砂轮,其圆周表面线速度一般可达30～50m/s。由于砂轮为脆性材料且转速高,机件运动速度较快,在砂轮安装及工件装卡不当或操作失误等情况下,均可能发生砂轮破碎而造成设备或人身事故。另外,磨削加工中产生大量微小的砂轮粉尘及金属磨屑,也会对人身体造成危害。因此,安全技术在磨削加工中显得特别重要。磨削加工的安全技术不仅反映在加工过程中,而且还贯穿于磨削机械的设计、制造、安装、使用、管理和维护等全过程,因此,只有对全过程的每一个环节进行安全控制,才能保证磨削加工的真正安全。一、对磨削设备的要求磨削加工是高速旋转的砂轮与工件作径向接触运动来完成材料切削的,因此磨削机械的砂轮主轴必须有足够的刚度,其安装砂轮部位的最小直径
Grinding is a flat with a high linear velocity of the workpiece surface machining a mechanical processing method. Common abrasive grinding wheel, the circumferential surface of the linear speed of up to 30 ~ 50m / s. As the wheel is brittle material and high speed, moving parts faster, in the installation of the wheel and the improper installation of the workpiece or the operation of errors, etc., may occur wheel broken and cause equipment or personal accident. In addition, a large number of grinding wheel grinding dust and metal debris, will also cause harm to the human body. Therefore, safety technology is particularly important in grinding. Grinding safety technology not only reflected in the processing, but also throughout the grinding machine design, manufacture, installation, use, management and maintenance of the entire process, therefore, only the entire process of each part of the safety control, In order to ensure the real safety of grinding. First, the requirements of grinding equipment Grinding is the high-speed rotation of the wheel and the workpiece for radial contact movement to complete the material cutting, grinding wheel spindle must have sufficient rigidity, the minimum diameter of the installation of grinding wheel parts
