摘要： PURPOSE: A device for compensating thermal displacement of a spindle for a machine tool is provided to obtain an optimal processing condition according to a driving condition in the spindle rotation speed change of a wide range by compensating the thermal displacement using a linear variable differential transformer. CONSTITUTION: A device for compensating thermal displacement of a spindle for a machine tool comprises an LVDT(Linear Variable Differential Transformer)(1), a signal processor(2), an NC controller(3), and a spindle transfer unit(4). The LVDT outputs different output voltage according to the position of a magnet core in the position change of the spindle. The signal processor connects the LVDT and generates a sine wave. The signal processor commutates a signal generated from the LVDT after applying to the LVDT and outputs after filtering. The NC controller senses the position in a shaft direction of the spindle from the signal input from the signal processor. The NC controller outputs a control signal to transfer a main shaft system as the value which is deviated from the standard position. The spindle transfer unit connects to the NC controller and transfers the main shaft system according to the control signal input from the NC controller.
