摘要:
The object of the present invention is a mobile group of a machine tool comprising a travelling support (4), a spindle carrier (6), a spindle (8), first measurement means suitable for measuring the axial advancement of the spindle relative to the spindle carrier, second measurement means suitable for measuring the axial advancement of the spindle carrier relative to the travelling support, second detection means suitable for detecting the thermal deformation of the spindle carrier and further detection means suitable for detecting the thermal deformation of the spindle carrier, between the front surface of the spindle carrier and a fixed reference position on the spindle carrier.
摘要:
The object of the present invention is a device for detecting the thermal deformation of a spindle of a machine-tool. The machine tool comprises a spindle carrier (6) and a spindle (8). The device comprises a spindle carrier cover (12) associable at the front to the spindle carrier for covering, at least partly, the spindle carrier opening allowing in any case the shifting of the spindle, and detection means fixed to the spindle carrier cover. The detection means are suitable for detecting the position of the signalling element of the spindle for measuring the hot deformation of said spindle in said retracted position.
