一、导轨的形式机床修理过程中,我们常碰到各种形式被磨损了的导轨。以车床为例: 1.C336六角车床,其前后导轨均为对称形式的棱形导轨(图1)。 2.C616普通车床,前导轨为对称棱形导轨、后导轨为矩形(图2)。 3.C620普通车床、前导轨为不对称棱形,后导轨为矩形(图3)。我们都知道,棱形导轨具有能自动调整的特性,不易积存尘屑,但也不易存油,其导向面承受较大的载荷。矩形导轨正好相反,其承 First, the form of rails Machine repair process, we often encounter various forms of worn rails. To lathe, for example: 1.C336 hexagonal lathe, the front and rear rails are symmetrical form of prismatic guide (Figure 1). 2.C616 ordinary lathe, the front rail is a symmetrical prism rail, the rear rail is rectangular (Figure 2). 3.C620 ordinary lathe, the front rail is asymmetrical prism, the rear rail is rectangular (Figure 3). We all know that prismatic guide with automatic adjustment of the characteristics of difficult to accumulate dust, but also not easy to save oil, the guide surface to withstand greater load. Rectangular rail exactly the opposite, its bearing
