摘要: A linear measuring machine is provided, the linear measuring machine having a base (11), a column (12) disposed on the base, a slider (14) elevatable along the column and an elevation driving mechanism (44) including a motor for lifting and lowering the slider. The linear measuring machine further includes a touch-and-back mechanism for driving the elevation driving mechanism in a direction for a probe (13) to move away from a measurement surface of the workpiece after fetching a detection value of a displacement sensor (45) when the probe touches the measurement surface of the workpiece and for stopping the elevation driving mechanism.
