Accordingly, the use in lathe of double housing planer, planer-type milling machine, vertical and similar machine tool and in repairing the job, have following a few problems are notable: (1) to double housing planer, planer-type milling machine, large establish a car, after using a certain number of time, adjust without repairing use oneself tool carrier workbench on plane is small sparsely dig goes to, want to reduce the surface roughness of the face that hold clip and the precision that raise a machine tool with this. Do the bending that can cause workbench cover so, change the interface of slideway quickly to accumulate, raised the possibility that pressure of slideway unit area and slideway grind. (2) the slideway precision for repair double housing planer, planer-type milling machine, large workbench establishing a car, the craft order that uses normally is: Restore lathe bed above all (or base) the precision of slideway, repair workbench again (or flower disc) slideway (it is as chromatic as lathe bed slideway commonly grind blow) . Next, install a workbench, the feet that use stuff examines the osculatory case of slideway, use the tool carrier of machine tool oneself that is repaired to machine workbench surface finally, what take out workbench installs clip face to go up is uneven. Such doing not only all one's previous efforts wasted, and workbench is used below the condition of bending very do not freely. Repairing craft order reasonably is: Before aing string of 1 come off work makes a stand, what machine workbench face first is cold make sclerotic layer, cooperate to blow with the lathe bed slideway that restored precision again grind, next reload answers workbench, with the plane on workbench of finish machining of oneself tool carrier (the metal with paper-thin take out) , examine the osculatory case of slideway finally. (Should adopt between the operating period of these 3) machine tools prevent generation cold the step that makes sclerotic layer. For example, workpiece is not installed directly go up in workbench face, hold card however waiting to fill up iron high, and wait to fill up iron high to be able to press need at any time dig is cut. In addition, be in perpendicular the direction at workbench T chamfer, certain distance does every other the transverse chamfer with an a few deep millimeter, also deserve further consideration.
