Abstract
A machine tool (1) includes a spindle (32) supported on a support surface (37a) of a support body (37) with such an orientation that the longitudinal axis of the spindle extends along the support surface (37a). The spindle (32) is movable in a vertical direction that is perpendicular to the longitudinal axis of the spindle (32). The support body (37) is provided with a ventilation hole (80) extending through the support body (37) between the support surface (37a) and a surface (37b) facing in the direction opposite to the support surface (37a), to open toward the spindle (32).
Claims4
A machine tool comprising:
- a headstock,
- a spindle rotatably supported by the headstock,
- a support body having a support surface that supports the headstock and an opposite surface that is located opposite to the support surface, and
- a moving mechanism disposed on the support surface of the support body, for moving the headstock vertically relative to the support surface, wherein
- the spindle has a longitudinal axis that extends along the support surface,
- the spindle is movable in a vertical direction, the vertical direction being disposed along the support surface and extending perpendicular to the longitudinal axis,
- the support body having a ventilation hole that extends from the opposite surface, through the support body, to the support surface, to open toward the spindle, wherein
- the machine tool further comprises a blower that is arranged at the opposite surface to forcibly flow air through the ventilation hole, and
- the blower is arranged upstream of the ventilation hole in terms of cooling airflow.
