DEVICE FOR DETECTING THERMAL DEFORMATIONS OF A SPINDLE OF A MACHINE-TOOL

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.
