1离心研磨法:普通的回转式研磨机高速回转时其物质(混合物)会围着研磨槽周围,工件与研磨石无相对运动,故无相对运动差,研磨作用就会大大的减弱 吊钩式抛丸机


而离心研磨法在回转头圆盘的回转轴上等距离的装上几个研磨槽,进行行星旋转运动,给予离心力,物质就会因离心作用围着在槽壁的回转外圆一侧,回转外盘圆旋转研磨一次,研磨槽逆转一次,物质往研磨槽内空间与上层部分接触的回转方向移动

物质因离心力的压力和强制流动速度,使物质中的游离研磨石与工件产生流动,因流动产生相对运动差,由于相对运动差的存在,因而产生研磨作用

回转速度在140—180rmin,与回转数成正比例的相对运动差以及离心力会增加

其研磨作用超过回转式研磨机的60倍,是振动研磨机的5—8倍

离心研磨机的研磨能力非常良好,显示很大的研磨力

较多的应用在钟表、电子、电气零部件等精密机械的光饰,尤其适合于小型工件的研磨

2回转研磨法:回转研磨法是在研磨槽内装好工件,研磨石,研磨剂,水给于所定的回转运动,使物质表面产生流动层,进行光饰的加工方法

这种研磨法比较适合于中小零件以及多品种小批量工件研磨

3振动研磨法:振动研磨法是在研磨槽内装好工件,研磨石,研磨剂,水给于振动,利用因振动而产生的研磨石和工件之间的相对运动差,进行研磨的加工方法

排除了回转式研磨机产生的净空间,发挥了100%的研磨槽内溶剂

这种研磨方法比回转研磨机工效提高3—5倍,而且被加工的工件无打痕,变形等现象

是目前被广泛采用的研磨方法

4水涡流式研磨法:水涡流式研磨法是在安装于垂直或水平面上的圆筒研磨槽内装入研磨石、水、研磨剂,随着研磨槽的回转,研磨石会因离心力而形成细密而具有刚性的研磨层

在研磨层内装入工件,会产生与研磨石相对运动差而形成的高效率的研磨作用


中译英:1 centrifugal grinding method: ordinary rotary grinding machine high speed rotation of its material(mixture)around the grinding groove around the workpiece and a grinding stone, no relative movement, so no relative motion, grinding effect will be greatly reduced While the centrifugal polishing method in turret disk rotary axis equidistant fitted with several grinding groove, planetary rotary motion, giving the centrifugal force due to the centrifugal effect, material will be around the walls of the slot rotary cylindrical side outer circle, rotary grinding time, grinding trough time, material to the grinding groove space the upper part of the rotary contact with moving direction The material because of the centrifugal force pressure and forced flow velocity, so that the material in the free abrasive stone and the workpiece to produce flow, due to flow to produce relative movement is poor, due to the relative movement of the difference, thus generating grinding effect Rotary speed in 140 - 180r  min, and the rotation number is proportional to the relative motion is poor and the centrifugal force will increase The abrasive action of rotary grinding machine more than60 times, is the vibration grinding machine 5-8 times Centrifugal grinding machine grinding ability is very good, showing great grinding force Used in watches and clocks, electronic, electrical components and other precision mechanical polishing, especially suitable for small workpiece grinding2 rotary grinding method: rotary grinding in grinding groove installed parts, grinding stone, polishing agent, water to the rotary motion, so that the material surface layer flow, light decoration processing method The grinding method is suitable for medium and small parts as well as many varieties of small batch workpiece grinding3 vibration grinding method: vibration grinding in grinding groove installed parts, grinding stone, polishing agent, water to use in vibration, produced by vibration grinding stone and relative movement between the workpiece is poor, polishing processing method Exclusion of the rotary grinding machine produces a net space, played100% of the grinding groove solvent This grinding method than the rotary grinding machine efficiency3to 5 times, and the processed workpiece without hitting marks, deformation phenomena It is widely used in the grinding method4 water flow type grinding method: water flow type grinding method is mounted on a vertical or horizontal plane of the cylindrical grinding groove into the grinding stone, water, abrasive, grinding grooves with rotary, grinding Shi Hui because of the centrifugal force and the formation of a fine and has a rigid abrasive layer In the grinding layer is mounted within the workpiece and grinding stones, will produce relative motion differential and the formation of the high efficient grinding action
