Integrated Granite Motion Systems vs Positioning Stages Mounted on a Granite Base
Differences and Similarities of High Precision Multi-Axis Positioning Systems Concepts
When it comes to high precision, granite-based, multi-axis motion systems, manufacturers have two fundamental options: Design a motion system where the granite base becomes an integral part, with bearings mounted directly on the granite slab and no need for a base plate – or, use off-the-shelf, discrete motion / positioning stages and mount them on a granite base or split-bridge granite structure.

How Air Bearings Provide Better Straightness and Flatness
Setup, Definitions and Measurement of Linear Air Bearings and Stages
When working with air bearings, we often describe the quality of motion as one of the key factors in selecting an air bearing; specifically, the straightness and flatness of travel of linear bearings and stages. Just how straight and flat? What levels of precision are achievable?
