B665牛头刨床原润滑系统设计简陋,其各部位皆采用定期注油润滑,仅手工加油的润滑点多达三十余处。由于各润滑点油量的多少不易控制,且润滑油的保持性差,致使各运动副得不到充分的润滑,因而磨损严重。为此滑枕导轨摇杆机构的内滑块经常因发生粘着磨损(即拉毛、咬焊、研死)而失效 B665 shaper original lubrication system design is simple, all parts of them are regularly lubricated, only hand lubrication points as many as thirty. Due to the amount of oil at each point of lubrication is not easy to control, and poor retention of lubricants, resulting in the movement can not be fully lubricated, and thus severely worn. For this reason, the inner sliders of the ram guide rocker mechanism often fail due to sticking and wearing (ie, napping, bite welding and grinding death)
