Detailed description of the invention
Be below the preferred example of a kind of planer-type height ray machine described in the utility model, therefore do not limit protection domain of the present utility model.
Please refer to Fig. 2 ~ 3, there is shown a kind of planer-type height ray machine, comprise the base 1 for carrying, described base 1 is equiped with planer-type crossbeam 2 and is positioned at the Y-axis drive unit 3 of this planer-type crossbeam 2 front portion, the guide rail of described Y-axis drive unit 3 is equiped with can along the workbench 4 of its slide anteroposterior, the top of described planer-type crossbeam 2 is equiped with X-axis drive unit 5 along the direction of described workbench 4, the guide rail of this X-axis drive unit 5 is equiped with the head 6 that can horizontally slip along it, also comprise the Z axis drive unit 7 be installed on described X-axis drive unit 5, described head 6 can slide up and down along the guide rail of this Z axis drive unit 7.
