Abstract:
1. A releasable arbor system for connecting an axially operating tool to a chucked arbor operationally rotating around a rotation axis, said arbor system comprising: a. an arbor including: b. a clamp body of said axially operating tool, said clamp body including: c. a tightening feature including: d. a circumferentially rigid snap feature having an engaging position and a releasing position, wherein at least during said tight-screwed interlocking said engaging position is established in which said snap feature is snap interlocking in a snap serration of said tightening feature such that said tightening feature is prevented at least from unscrewing said first thread, and wherein during said releasing position said snap feature disengages said snap serration for unscrewing said tightening feature from said first thread; and wherein said pressed contact provides a releasable fix that is axially, radially and circumferentially form fitting such that said tight-screwed interlocking remains substantially unaffected of an operational tilt torque and substantially unaffected by an operational load torque.
