XY positioning stage

This is an example of a Lasik eye surgery application where the end user required a precise XY positioning system capable of making high speed micro positioning adjustments. Precise repeatability and the unit's ability to hold position was a critical requirement. The customer was looking at Del-Tron's standard linear ball slides, but the complexity of assembling the high number of ball slides the application required made it unfeasible. Del-Tron's engineers were able to solve this problem by designing a series of custom ball slides that could be integrated into the assembly to greatly reduce linear friction. Six custom Del-Tron linear slides were incorporated into the design to provide the linear motion necessary. These linear ball slides were also designed with stainless steel internals and ceramic ball bearings to reduce the magnetism transferred by the voice coil motors to the system's work surface. This compact design helped our customer offer a cost effective alternative to Lasik procedures.
