摘要 |
<p>An improved tool holding apparatus including a collet chuck or a steel ball chuck that clamps a pull bolt (13), which defines the forward end portion of a tool, by resilient force applied thereto from a coned disc spring (36). The tool holding apparatus further includes a temporarily clamping device (33,34) which is buried in a sleeve to clamp the pull bolt temporarily. Clamping force applied by the temporarily clamping device is set at such a level that an arm can draw the tool from a main spindle by gripping the rear end portion (11) of the tool.</p> |
