金属切削机床(例如铣床、刨床)工作台面上的T形槽给操作者在清除切屑时带来不便。为此,日本生产了一种“槽盖”,将它嵌在T形槽内,其效果非常明显。这种“槽盖”的外形及嵌在T形槽内时的剖面形状如图a、图6所示,槽盖略低于工作台面2～3毫米,在槽盖的长度中心线上开有一排用于将切削油剂漏 Metal cutting machine tools (such as milling machines, planing machines) T-slot on the work surface to the operator in the removal of the chip inconvenience. To this end, Japan produced a “slot cover”, which is embedded in the T-slot, the effect is very obvious. This “groove cover” shape and embedded in the T-shaped groove when the cross-sectional shape shown in Figure a, Figure 6, the groove cover slightly lower than the table 2 to 3 millimeters, Row for cutting oil leakage
