ABTech’s precision mechanical spindles address the high-speed motion needs for different weights and part sizes. High precision angular contact bearings are incorporated into stages that are designed and manufactured in-house to extremely tight geometric tolerances. The result is superior performance in radial, axial, and angular (tilt/coning) error motions. These are ideal as stand-alone units and/or multi-axis assemblies, for optical scanning, machining, and grinding, to name a few.
Precision motion comes in many forms and applications, each with its own set of pertinent specifications. Diversity in today’s applications creates unique requirements, we provide configuration flexibility as an integral part of our design philosophy. All spindles can be customized with a variety of options and accessories including motor drives, vacuum worktables, high-resolution optical encoders, digital readout (DRO) displays, inspection-grade granite surface plates, and more.
In addition to the options and accessories, the material selection of spindles is a key focus of our applications engineers. For harsher environments, best accuracy, precision, and stability we use hardened stainless-steel components. Focused on cost, ABTech will utilize the efficiencies of hard-coated aluminum construction. Our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.
Features & Benefits
Superior Mechanical Motion
ABTech mechanical spindles are superior in performance and quality. While angular contact bearings can be purchased from many manufacturers, the key to a high-performance spindle is in the geometry and overall quality of the mating components. By leveraging our knowledge and experience gained in producing the extreme tolerances required for air bearings, ABTech mechanical bearings achieve radial and axial error motion of < +/-20.0 µ” (+/-.50 micron).
Configuration Flexibility to Meet Your Specific Needs
