XY Table (4)
An XY stage is used for cutting, engraving, and marking by proffesionals. The standard versions of this machine range from 51"x100" back to 15"x15". Most of the manufacturers allow for wide configuration latitudes making it possible for a client to acquire the right XY table for their application or applications. Standard XY table lines meet and even exceed the performance ratings of any competitor's product as they are manufactured from the best, heavy duty steel forms, which include stainless steel. When built, these XY tables are built to last the test of time while requiring the least amount of maintenance possible. All working XY stage tops are designed to be monotonic for firmness, stressed relieved in order to place the least amount of stress on the environment as possible and ground to precision level of .011".bearing blocks, precision rails as well as other components are utilized to acquire a very repeatable and accurate operation, typically +/- .002"/feet. An XY table that features higher accuracy is available with the minimum amount of vibration allowed through extensive experience in vibration by this manufacturer.
A smaller precision XY table may be utilized of machines or drill press to accurately locate a workplace. An example of XY table measures ninety millimeter by two hundred millimeters and has 3 eight millimeter slots. The complete assembly for such an XY table is 10.15" in width, 8.5" in depth and 2.5" in height. The travel on the X axis is 5.31" and the travel on the Y axis is 2.76". The XY table's height is 2.36. The base of the machine measures 3.94" by 6.89" while the controls are graduated at the level of 0.001" while hand wheel turn moves the XY table 0.050". The materials used in the manufacture of this XY table are steel and cast iron featuring adjustable gibs featured on not only one axis, but on both of the axes.
A XY table is a two axis positioning machine that is accurate, easy to use and lightweight. An XY table is employable in a number of automation tasks including an XY table that demands two freedom degrees, which are among the most difficult and complex automation applications of all. Such tasks of an XY table includes drilling small circuit board holes and working on test tube racks. Some XY tables feature aluminum frames for cutting back on weight levels and stability, shafts are made of solid steel and bearings are made of bronze. They provide for longer life and higher accuracy with the least amount of flexure.
Software compensates automatically for whatever belt stretch that may be experienced, which results in better accuracy. Each axis of the XY table has an attached home switch that provides feedback back to the regulator giving the software one reference point for all future positioning commands. Such an XY stage package could include documentation, setup tools, home switches, all the necessary hardware, and the table for linear positioning. The possible tools would be a camera, an engraver, a sensor, an adhesive dispenser, a pneumatic gripper, a miniature drill, and a test probe. Payloads may differ, but some XY tables can work with about 15 pounds, as any heavier will show decreased accuracy and speed.
