摘要：
A device for detecting the position of a wheel head of a grinding machine is provided with a housing secured to the wheel head and a support rod secured at its opposite ends to a stationary base in parallel relation with the moving direction of the wheel head. The support rod passes through the housing at a pair of holes formed on opposite end walls of the housing. A linear scale is secured to the housing within the housing, and a scanning unit is fixed on the support rod within said housing for reading scale gratings on the linear scale when the housing is moved bodily with the wheel head relative to the support rod.
