Abstract
A machine for machining a workpiece with at least one revolving or rotating tool has a work spindle with a shaft (5), whose temperature is monitored by means of at least one temperature sensor (26). The temperature sensor is detected in contactless fashion. The sensor (26) is preferably a radiation-sensitive sensor, which detects the temperature radiation output. by the shaft (5). In triggering the positioning drive mechanisms, the control unit (35) of the machine (1) takes into account the temperature expansions of the shaft (5) that result from the temperature changes in the shaft. The positioning drive mechanisms serve to position a tool (6), carried by the shaft (5), relative to the workpiece (2). A machining precision is thus achieved that is independent of the temperature and temperature changes of the machine (1) overall, of temperature changes in the coolant—lubricant, and of temperature changes in the tool (6) and the shaft (5), that can all be caused by the power converted at the machining site.
