Rotary Tables

Rotary Air Bearing Tables – Accuracies to 2.0 µ”

ABTech’s standard line of high precision rotary air bearing tables (AT Series) and Heavy-Duty Rotary Tables (HDRT Series) are ideal for low speed TIR measurements, optical inspection, precision assembly or light machining and grinding where radial and axial accuracies down to 2.0 µ” are required. Available with tilt and center worktables, precision fixtures, 3-Jaw chucks, vacuum feed through the center, and motor drives. Manufactured of 440CSS and hardened to 58 – 60 Rc make these rotary air bearing tables the most robust available.

Hydrostatic Rotary Tables

More than 4 times stiffer than an air bearing, oil hydrostatic rotary tables are ideal for the most demanding high precision machine tool applications. If extreme stiffness and high load capacity are key to your application, let our staff help you select the right oil hydrostatic rotary table. Our systems include the Hydrostatic Power Unit (HPU) which consists of a low speed precision pump, Pressure sensor for closed loop operation, filtration system, and reserve tank.
