The Difference Between Stage-on-Granite and Integrated Granite Motion Systems

Brian Fink
Product Manager

The selection of the most suitable granite-based linear motion platform for a given application depends on a host of factors and variables. It is crucial to recognize that each and every application has its own unique set of requirements that must be understood and prioritized in order to pursue an effective solution in terms of a motion platform.

One of the more ubiquitous solutions involves mounting discrete positioning stages onto a granite structure. Another common solution integrates the components that comprise the axes of motion directly into the granite itself. Choosing between a stage-on-granite and an integrated-granite motion (IGM) platform is one of the earlier decisions to be made in the selection process. There are clear distinctions between both solution types, and of course each has its own merits — and caveats — that need to be carefully understood and considered.

To offer better insight into this decision-making process, we evaluate the differences between two fundamental linear motion platform designs — a traditional stage-on-granite solution, and an IGM solution — from both technical and financial perspectives in the form of a mechanical-bearing case study.
