MicroCentric Precision Workholding Technology High Precision Air Chucks

MicroCentric Improve productivity and lower the cost of secondary machining operations . . . . . Radial Runout Lateral Runout through high concentricity. Holding close concentricity tolerances during each machining operation not only reduces scrap rates, but also allows you to leave less material for finishing operations. Therefore, you reduce cycle time and improve tool life of finishing operations. And MicroCentric air chucks give you the capability to improve workpiece roundness, squareness, and parallelism as well.

MicroCentric Air Chuck Models Rotating Air Chucks Rotating air chucks are ideal for precision turning and cylindrical grinding applications that call for close concentricity and squareness tolerances. Rotating air chucks are available in sizes from 3 to 10 inches in diameter, in 3 and 2 jaw configurations. Stationary Air Chucks Stationary air chucks are ideal for milling, drilling, tapping, welding, and other applications requiring a compact self-contained workholding fixture. Stationary air chucks are available in sizes from 3 to 10 inch diameter, in 3 and 2 jaw configurations. Long Stroke Air...

Rotating air chucks are ideal for precision turning and cylindrical grinding applications that require close concentricity, squareness, and parallelism tolerances. Variable clamping force enables clamping of thin-walled and other fragile parts with minimal distortion. All models, except the 3-50, feature a coolant or air passage through the center of the chuck.

Long stroke air chucks feature extended jaw opening for load clearance or to clamp a range of diameters without changing top jaws. Long stroke chucks are available in rotating and stationary configurations. Their high accuracy makes them ideal for clamping headed workpieces for turning, grinding, or milling/drilling applications. Special models with total jaw stroke of .500" (12.7mm), .750" (19.1mm), and 1.000" (25.4mm) are also available. Please call for information. Chuck Chuck # of Chuck Jaw Max. Max. air Max.

HST High Speed Air Chucks HST High Speed Air Chucks feature a titanium chuck body and are actuated by a patented external wedge design that maintains clamping force at high spindle speeds without counterweights. This revolutionary design minimizes the effects of centrifugal force resulting in consistent clamping force throughout the chuck's rpm range. HST chucks are available in standard, HS, and BP models. The HS models are dynamically balanced and feature MicroCentric's patented NR50 non-rotating air tube system. The NR50 design eliminates vibration caused by rotating air at higher spindle...
