Northfield Precision Instrument Corp. introduces its 5C Collet Chuck. The 5C is interchangeable with our standard 4 inch or 6 inch chucks.

The chucks are air-actuated, use Northfield's standard air feed tubes (wet or dry), have the same bolt pattern as the company's standard 4 inch models. All components are hardened and ground to 58 to 63 HR. All diameters are ground within 0.0001" T.I.R.

The chucks uses standard 5C collets, and also accepts 5C expanding collets. They can run at speeds in excess of 8,000 rpm.

  • Rockwell hardness number ( HR)

    Rockwell hardness number ( HR)

    Number derived from the net increase in the depth of impression as the load on the indenter is increased from a fixed minor load to a major load and then returned to the minor load. The Rockwell hardness number is always quoted with a scale symbol representing the indenter, load and dial used. Rockwell A scale is used in connection with carbide cutting tools. Rockwell B and C scales are used in connection with workpiece materials.

  • chuck

    chuck

    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

  • collet

    collet

    Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
