Oil Hydrostatic Rotary Tables

ABTech’s line of precision oil hydrostatic rotary tables is built for the most demanding applications. Oil hydrostatic fluid film provides high load capacity and extreme stiffness. Every stage provides ultra-smooth motion, sub-micron accuracy, and absolute repeatability. They are designed and manufactured in-house to extremely tight geometric tolerances and have no contact mechanical parts to wear or create drag. This allows for decades of reliable, maintenance-free motion.

Our hydrostatic rotary tables are commonly used in a wide range of machining and grinding applications where medium to high loads are coupled with the need for smooth and repeatable motion. They are ideal as stand-alone units and/or multi-axis assemblies, typically seen in machining and grinding systems.

Accurate, Repeatable, Smooth Motion

Similar to air bearings, hydrostatic bearings provide significant advantages over mechanical rotary motion. Because they have no contacting parts to wear, hydrostatic bearings provide ultra-smooth, repeatable and maintenance-free motion.

Superior Durability

Configuration Flexibility to Meet Your Specific Needs

Motor Drive Options

With proper selection and integration of high-performance brushless DC servo motors ABTech’s air bearing rotary tables provide ultra-smooth and precise rotary motion. With high torque, high performance motor drives, our motion experts will gather your specific requirements and work closely with our motor suppliers to create/select a motor drive that suits your specific application. Whether you need sub-micron position accuracy with minimal settle time and stringent following error specifications, high-speed constant motion, or a combination of both there is an ABTech rotary table that will meet your needs.

The motor drives are designed to accommodate a wide range of precision motion applications such as optical metrology; circular geometry gages; and micro machining with ultra-precision scanning, velocity control, speed regulation and precision indexing.

ABTech’s modular design approach facilitates multiple system configurations to optimize the price-for-performance required in your application. This approach allows the user to define the level of control desired for the most cost-effective solution. Our complete engineering services allow us to respond quickly to provide a solution to your O.E.M. requirements for ultra-precision rotary motion.

"We use 2 ABTech air-bearing spindles with tip/tilt and centering capability in our facility. These units are used for precision assembly and final metrology. We have never had an issue with either one, and the ABTech team is a great partner for us. We will be adding more systems as our young organization continues to grow".
