About Stage

In industrial products, a stage generally refers to a movable table. For example, in the case of a microscope, it becomes difficult to manually move the magnified object to the observation point. Therefore, in many cases, it is possible to finely adjust the movement in the X, Y, and Z directions with the dial little by little. As another example, in a processing machine such as a lathe, cutting is performed by bringing a workpiece, which is a material to be cut, close to a cutting tool and moving it to a predetermined depth of cut, so that the work is brought into contact with the rotating cutting tool. Create the desired final shape. In addition, some robots called SCARA robots move on a movable table in the vertical and horizontal directions, i.e., the first and second axes, and move the opposing rods in the vertical and rotational directions to move the rods in the third and fourth axes. There is something that moves the . In other words, it is achieved by combining a movable XY table that can control two of the four axes. All of the above examples are difficult to achieve with a fixed table, so they must be mobile.
