Single column vertical lathe column worktable maintenance

Inspection method for verticality of column guide rails to the base surface or workbench surface

Usually with pillars http://www.btjxjt.com The machine tool; For machines such as Longmen planer, horizontal boring machine, vertical lathe, vertical drilling machine or rocker drilling machine, when assembling the column and bed, the verticality of the column guide rail and the worktable should be within the tolerance range.

The inspection method for the verticality of the vertical lathe column guide rail to the worktable. On the workbench, at a distance equal to the center of the workbench, two equally high cushion blocks are placed away from the two ends of the ruler. The level is placed on the ruler and against the guide surface of the column, and the verticality of the column and workbench are checked separately. The level should be checked at the upper and lower positions of the column guide rail. The maximum algebraic difference between the readings of the level on the straightedge and the level on the column is the error in perpendicularity.
