US 2022/0266350 A1 · TOOL HOLDER AND MACHINING METHOD

Abstract

A tool holder (100) comprising: an outside section (10) connected and fixed to a main shaft housing; a rotation input section (20) that is gripped by the main shaft and caused to rotate at a first rotation speed r1; a rotation output section (40) that has the rotational force from the rotation input section (20) transmitted thereto and rotates at a second rotation speed r2 that is different from the first rotation speed r1; a slider (60) that is moved in a first direction that intersects the rotational axis (Os) of the main shaft, as a result of the force from the rotation output section (40); a cutting edge (70) that is moved in the first direction by the slider (60) and is rotated by the rotation input section (20); and a detection mechanism (90) for detecting that the cutting edge (70) is at the origin position.

Dependent claims

A tool holder which is used in a machine tool comprising a spindle for rotating a tool, the tool holder comprising:

an outside portion which is connected and affixed to a housing of the spindle,
a rotation input part which is gripped by the spindle and which is rotated at a first rotation speed,
a rotation output part to which rotational power is transmitted from the rotation input part and which is rotated at a second rotation speed different from the first rotation speed,
a slider which is moved in a first direction intersecting the rotational axis of the spindle by power from the rotation output part,
a cutting edge which is moved in the first direction by the slider and which is rotated by the rotation input part, and
a detection mechanism for detecting that the cutting edge is in an origin position.
