机床上的內圓磨具一般都采用滾动軸承,由于高速旋轉时鋼珠与內外滾道及保持架的摩擦,产生了較高的发热量,这种热量就会导致机床的温度升高而发生热变形,影响到磨具与头尾架等高,对加工精度、机床本身精度以及軸承寿命都有一定的影响。为了减低摩擦系数,在我国絕大多数的磨具是采用潤滑油作潤滑,方式上大多采用滴式和渗式,前者是把油直接滴进軸承中,后者是軸上有一段沉割油池,两 Internal circular grinding machine tools are generally used in the rolling bearing, due to high-speed rotation of the ball and the raceway and cage friction, resulting in a higher heat, the heat will lead to the machine temperature increases occur Thermal deformation, affecting the abrasive and head and tail frame contour, the machining accuracy, precision machine tools and bearing life have a certain impact. In order to reduce the coefficient of friction, the vast majority of abrasive in our country is the use of lubricants for lubrication, the way most of the use of drip and infiltration, the former is the oil directly into the bearing, which is a shaft on the sunken oil Pool, two
