Claims

[Scope of utility model registration request]

A workpiece support stand that rotatably supports a workpiece, and a grindstone that rotatably supports the grindstone that grinds the inner surface of the workpiece, and is movable in a direction along the central axis of rotation of the grindstone. a grindstone support; a support rotating means for rotating the grindstone support or the workpiece support to change the angle formed between the rotation center axis of the grindstone and the rotation center axis of the workpiece; Measuring means for measuring distances from the rotational center axis of two predetermined locations along the rotational center axis of the workpiece on the inner surface of the workpiece while the inner surface of the workpiece is being ground by the grindstone; gradient detection means for detecting a gradient on the inner surface of the workpiece based on the distances respectively measured by the measurement means; and convergence of the gradient to a predetermined value based on a detection output from the gradient detection means. an internal grinding machine comprising: control means for controlling the support table rotating means to rotate the support base;
