切削加工:珩磨 用镶嵌在珩磨头上的油石(也称珩磨条)对精加工表面进行的精整加工(见切削加工)。珩磨主要用于加工孔径为5～500毫米或更大的各种圆柱孔﹐如缸筒﹑阀孔﹑连杆孔和箱体孔等﹐孔深与孔径之比可达10﹐甚至更大。在一定条件下﹐珩磨也能加工外圆﹑平面﹑球面和齿面等。圆柱珩磨的表面粗糙度一般可达R0.32～0.08微米﹐精珩时可达R0.04微米以下﹐并能少量提高几何精度﹐加工精度可达IT7～4。平面珩磨的表面质量略差。 珩磨一般采用珩磨机﹐机床主轴与珩磨头一般是浮动联接﹔但为了提高纠正工件几何形状的能力﹐也可以用刚性联接。珩孔时﹐珩磨头外周一般镶有2～10根油石﹐由机床主轴带动在孔内旋转﹐并同时作直线往复运动﹐这是主运动﹔同时通过珩磨头中的弹簧或液压力控制油石均匀外涨﹐对被加工的孔壁作径向进给。图1内圆珩磨示意图 为内圆珩磨示意图。珩磨头每分钟往复次数与转数之比应取非整数﹐使磨料在工件表面形成的加工痕迹成为交叉的网纹而不相重复。图2珩磨运动轨迹 为单条油石在孔内珩磨时的运动轨迹。油石上下往复一次﹐工件回转一圈多。粗珩油石的磨料粒度为120～180﹐精珩用W28以下的细粒度油石。油石宽为3～20毫米﹐长度约为孔长的1/3～3/4。油石在孔内往复移动时﹐两端超越孔外的长度不宜大于油石全长的1/3﹐否则易产生喇叭口﹔但超程小于油石长度1/4时﹐又会使孔呈鼓形。外圆﹑平面的珩磨原理和操作要求与内圆珩磨相同。 珩磨余量一般不超过0.2毫米。珩磨的圆周速度﹐对钢材加工约为15～30米/分﹐对铸铁或有色金属加工可提高到50米/分以上﹔珩磨的往复速度不宜超过15～20米/分。油石对孔壁的压力一般为0.3～0.5兆帕﹐粗珩时可达1兆帕左右﹐精珩可小于0.1兆帕。由于珩磨时油石与工件是面接触﹐每颗磨粒对工件表面的垂直压力只有磨削时的1/50～1/100﹐加上珩磨速度低﹐故切削区的温度可保持在50～150℃范围内﹐有利于减小加工表面的残余应力﹐提高表面质量。为了冲刷切屑﹐避免堵塞油石﹐同时降低切削区温度和降低表面粗糙度﹐珩磨时采用的切削液要有一定的工作压力并经过滤。切削液大都采用煤油﹐或煤油加锭子油﹐也有采用极压乳化液的。
