Abstract
Follwing the 1st report, it was proposed to incorporate two concentric cooling jackets into a spindle unit for compulsory cooling. The inner jacket is for heat exchange with overcooled oil, and oil of a constant temperature is circulated through the outer one so that the temperature distribution of the head unit may become uniformly moderate. In addition, the feed-forward temperature control system was developed to control the oil temperature prior to heat generation at the spindle bearings. In this paper, the effectiveness of the proposed dual cooling jacket and feed-forward temperature control system was investigated though experiments using a bench lathe model. It has been clarified through the experiments that the feed-forward temperature control system with the dual cooling jacket structure is effective to decrease the thermal deformation of the spindle unit and to achieve ultraprecise machining.
