Chuck Jaw Quick-Finder App

March 13, 2013

SCHUNK has two new programs to help users quickly find the right type of jaws for their chuck.

The SCHUNK chuck jaw quick-finder makes tracking down the suitable standard chuck jaw simple. By putting in the chuck manufacturer, type, size, and details, the users will receive a comprehensive list of all relevant chuck jaws. The tool includes lathe chucks from Berg, Forkardt, Howa, Kitagawa,mmK Matsumoto, Rohm, SCHUNK, and SMW-Autoblok. Users have access to more than 1,200 chuck jaw types, and once found, can be ordered from an authorized SCHUNK distributor. You will find the chuck jaw quick-finder on the internet, free of charge, at

SCHUNK also introduced the world's first chuck jaw app for your iPad or iPhone. It is similar to the quick jaw finder, and allows users to receive a quote on the jaws they selected. This free app is available to download at The App Store under the headings "Chuck Jaws" or "SCHUNK."

Related Glossary Terms

  • 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.

  • lathe


    Turning machine capable of sawing, milling, grinding, gear-cutting, drilling, reaming, boring, threading, facing, chamfering, grooving, knurling, spinning, parting, necking, taper-cutting, and cam- and eccentric-cutting, as well as step- and straight-turning. Comes in a variety of forms, ranging from manual to semiautomatic to fully automatic, with major types being engine lathes, turning and contouring lathes, turret lathes and numerical-control lathes. The engine lathe consists of a headstock and spindle, tailstock, bed, carriage (complete with apron) and cross slides. Features include gear- (speed) and feed-selector levers, toolpost, compound rest, lead screw and reversing lead screw, threading dial and rapid-traverse lever. Special lathe types include through-the-spindle, camshaft and crankshaft, brake drum and rotor, spinning and gun-barrel machines. Toolroom and bench lathes are used for precision work; the former for tool-and-die work and similar tasks, the latter for small workpieces (instruments, watches), normally without a power feed. Models are typically designated according to their “swing,” or the largest-diameter workpiece that can be rotated; bed length, or the distance between centers; and horsepower generated.
