1.離心研磨法：普通的回轉(zhuǎn)式研磨機(jī)高速回轉(zhuǎn)時(shí)其物質(zhì)(混合物)會(huì)圍著研磨槽周圍，工件與研磨石無(wú)相對(duì)運(yùn)動(dòng)，故無(wú)相對(duì)運(yùn)動(dòng)差，研磨作用就會(huì)大大的減弱。而離心研磨法在回轉(zhuǎn)頭圓盤的回轉(zhuǎn)軸上等距離的裝上幾個(gè)研磨槽，進(jìn)行行星旋轉(zhuǎn)運(yùn)動(dòng)，給予離心力，物質(zhì)就會(huì)因離心作用圍著在槽壁的回轉(zhuǎn)外圓一側(cè)，回轉(zhuǎn)外盤圓旋轉(zhuǎn)研磨一次，研磨槽逆轉(zhuǎn)一次，物質(zhì)往研磨槽內(nèi)空間與上層部分接觸的回轉(zhuǎn)方向移動(dòng)。物質(zhì)因離心力的壓力和強(qiáng)制流動(dòng)速度，使物質(zhì)中的游離研磨石與工件產(chǎn)生流動(dòng)，因流動(dòng)產(chǎn)生相對(duì)運(yùn)動(dòng)差，由于相對(duì)運(yùn)動(dòng)差的存在，因而產(chǎn)生研磨作用?；剞D(zhuǎn)速度在140—180r/min，與回轉(zhuǎn)數(shù)成正比例的相對(duì)運(yùn)動(dòng)差以及離心力會(huì)增加。其研磨作用超過(guò)回轉(zhuǎn)式研磨機(jī)的60倍，是振動(dòng)研磨機(jī)的5—8倍。離心研磨機(jī)的研磨能力非常良好，顯示很大的研磨力。較多的應(yīng)用在鐘表、電子、電氣零部件等精密機(jī)械的光飾，尤其適合于小型工件的研磨。
2.回轉(zhuǎn)研磨法：回轉(zhuǎn)研磨法是在研磨槽內(nèi)裝好工件，研磨石，研磨劑，水給于所定的回轉(zhuǎn)運(yùn)動(dòng)，使物質(zhì)表面產(chǎn)生流動(dòng)層，進(jìn)行光飾的加工方法。這種研磨法比較適合于中小零件以及多品種小批量工件研磨。
3.振動(dòng)研磨法：振動(dòng)研磨法是在研磨槽內(nèi)裝好工件，研磨石，研磨劑，水給于振動(dòng)，利用因振動(dòng)而產(chǎn)生的研磨石和工件之間的相對(duì)運(yùn)動(dòng)差，進(jìn)行研磨的加工方法。排除了回轉(zhuǎn)式研磨機(jī)產(chǎn)生的凈空間，發(fā)揮了100%的研磨槽內(nèi)溶劑。這種研磨方法比回轉(zhuǎn)研磨機(jī)工效提高3—5倍，而且被加工的工件無(wú)打痕，變形等現(xiàn)象。是目前被廣泛采用的研磨方法。
4.水渦流式研磨法：水渦流式研磨法是在安裝于垂直或水平面上的圓筒研磨槽內(nèi)裝入研磨石、水、研磨劑，隨著研磨槽的回轉(zhuǎn)，研磨石會(huì)因離心力而形成細(xì)密而具有剛性的研磨層。在研磨層內(nèi)裝入工件，會(huì)產(chǎn)生與研磨石相對(duì)運(yùn)動(dòng)差而形成的高效率的研磨作用。

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 grinding.
2 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 grinding.
3 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 method.
4 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.
