There are different types of XY motors in the market, created for precision and accuracy; however, the differences in these systems may just be a slight change to the table’s operations. For example, we have the XY tables that come with stepper motors, to aid in performance, and thus increase efficiency, effectiveness, precision, accuracy, stability, and enhanced productivity. Other types of XY tables include the miniature XY table and the XY Cartesian system, among others. It is commonplace to think both tables are the same, and that is due to the fact that they have physical similarities, one of which is the axes that both tables have (X and Y).
While the miniature XY table and XY Cartesian system may have some similarities, it is important to know that they are not entirely the same, because they actually have a major difference:
- Load Position
One of the main differences is in the load position. In the case of the mini XY table, the load is usually positioned on the Y axis, and for the Cartesian system, the load’s position is cantilevered. The mini XY table positions load that way, in order to prevent the creation of moments around that axis. When dealing with a project that requires placing the load on a horizontal plane or between axes, the best positioning can be gotten from using the miniature XY table.
This is one of the reasons why a lot of industries and sectors usually adopt the use of the mini table, not just because it is easier to use, but because the load positioning technique helps to achieve better precision and accuracy, which will invariably ensure that productivity is also enhanced.
- Rotational Component and End Effector
The Cartesian system functions with a rotational component and an end effector that is used in changing the orientation of the load, however, this is different in the mini XY table, and that is partly because the load positioning is different for both of them.
There are no doubts about the fact that the Cartesian system and their gantry robots and systems are prevalent. However, when it comes to handling projects that require precision, then the XY tables are best suited for the job because they have high positioning and travel accuracies, their structure is rigid, and they are also compact
There are so many applications where the Cartesian systems are used with maximum long strokes on the different axes, and some of the common applications include assembly, dispensing, and pick-and-place. The position of the load on the axis determines the moment created on the axis.
Most times, the miniature XY tables are used when there are high precision tasks to attend to; hence the guideway to make the whole process smooth, is the crossed roller slides, as they make the travel flat and smooth. The drive mechanisms used for the facilitation of movement in the system is usually a linear motor or ball screw (sometimes, pitch lead screws are used to.) A common example of the XY table in action is when a semiconductor wafer needs to be inspected, it is then positioned on the table for inspection, or the table can be used to hold a part of the semiconductor in place for machining operations to begin.
It is important to note that both systems have their unique abilities, and their use is dependent on the nature of the project, the expected outcome, and the industry that needs it. Hence, it is imperative that you identify the project properly, before opting for one of the tools. However, the mini XY table takes accuracy, stability, and precision several notches higher, and that makes it a sort-after table for use with precision jobs. Furthermore, for ease, and also to enhance productivity, there is the tendency for some industries and people to opt for the mini XY table with stepper motors, because the table performs well, and brings about a precision and stability that that is unmatched. It is also important to know that the motorized table is perfect for those interested in generating a great deal of torque at velocities that are considerably low.
