No Static Friction Spindles
Featured Product from ABTech, Inc.
Air Bearing Spindles
ABTech’s high precision air bearing spindles provide the ultimate performance utilizing a proven and robust design. High stiffness, load capacity and very low error motion make these spindles ideal for precision machining, grinding, single point diamond turning, and high precision scanning. Available with integral brushless dc motor and encoder in low speed configurations for work holding or higher speed for grinding and scanning applications.
These orifice compensated air bearing spindles use a single piece of 440 CSS shaft and thrust plate with 660 bearing bronze journal providing a proven, robust and forgiving design. Available in a variety of sizes and speeds with a flange, foot, or a-thermal mounting.
Optional motion controllers incorporate a digital amplifier with easy-to-use programmable controls and digital spindle speed readout. Fully integratable with your existing CNC controller.
With this modular design approach and complete engineering support capabilities ABTech will respond quickly to provide a custom solution to your unique O.E.M. needs for ultra-precision motion. No need to settle for standard catalog offerings for your application.
Configuration Flexibility to Meet Your Specific Needs
Part of our “Pride in Precision” philosophy means providing you with the precise solution needed. We don’t believe selling our customers more, or less, than what their application calls for. For over two decades working with our customers we’ve developed a broad range of options and accessories to address the majority of ultra-precision motion applications. (See options and accessories for a complete list.)
No matter how broad our product options, we realize they don’t address every possible application. Our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.
