Abstract
A measuring machine having a base ( ), a touch signal probe (P), a moving mechanism ( ) for retaining the touch signal probe (P) movably in three-dimensional directions, and a controller ( ) for controlling a movement of the moving mechanism ( ) and for acquiring coordinates value of respective axes based on a contact signal from the touch signal probe (P) to measure a dimension etc. of a workpiece based on the coordinates value is provided. Main structural members structuring the moving mechanism ( ), more specifically, a column ( ), a supporter ( ), a X-beam ( ), a Z-axis structure ( ) and a Z-axis spindle ( ) are made of aluminum or aluminum alloy including aluminum as main component, which has large thermal conductivity, thereby making temperature distribution uniform to improve geometrical accuracy.
