Horizontal boring machine maintenance * repair

The unevenness of the boring machine maintenance worktable facing the worktable movement

Place a cast iron ruler along the vertical and horizontal directions on the workbench. Fix one thousandth on the machine tool, so that the micrometer head is on the inspection surface of the cast iron ruler. Move the slide or workbench and inspect it in the vertical and horizontal upright planes respectively.

Their errors are calculated separately. The maximum difference in micrometer readings is the error in non parallelism. When the inspection workbench moves longitudinally, it should be clamped in the middle position of the slide. When the inspection workbench moves laterally, the slide should be clamped in the middle of the bed guide rail

Rotating spindle inspection. The maximum difference in dial gauge readings is the error of axial movement.
