Rack & Pinion Application Stories

Integrated Rack Simplifies Machine Design on Waterjet Machine

Customer's Problem

A manufacturer of waterjet cutting machines needed a axis drive solution for a new traveling gantry machine.  They wanted to reduce the amount of machining needed for a typical rack & pinion drive, while simplifying assembly and alignment of the racks to their linear guides.

Atlanta's Solution

Choosing from their wide range of standard rack & pinion drives, Atlanta offered an integrated rack to mount directly with their linear guide.  The rack and guide assembly was then mounted to their machine frame and fixed in place.  Since the rack and guide were already aligned to each other, the assembly time needed was reduced.

A split-pinion and servo-worm reducer were used with the integrated rack to provide a precision axis drive.  The manufacturer was able to achieve very accurate results in their finished parts.
