Abstract
A cutter holder assembly has a cutter holder, a collet disposed in the cutter holder and having a positioning groove and a mounting cavity, a cutter set mounted in the collet, and a resilience tightening set mounted in the mounting cavity of the collet. The cutter set includes a cutter body and a positioning protrusion engaged with a limiting groove of the positioning groove. The resilience tightening set includes a spring room, a spring disposed in the spring room, and a position ball movably disposed in and partially extending out of the spring room. The position ball is pushed by the spring to push the cutter set to keep the positioning protrusion tightly abutting against a surface of the limiting groove, thereby reducing a longitudinal assembling gap between the cutter set and collet.
