摘要： A circular arc slide apparatus that achieves improved precision and a reduction in costs is provided. The circular arc slide apparatus comprises a lower plate, an upper plate, and a circular arc track provided between the lower plate and upper plate. Guide rail portions are provided in an upper surface of the lower plate and a lower surface of the upper plate, and circular arc curve-shaped guide grooves that constitute the circular arc track are provided in opposing planar surfaces of the guide rail portions. The guide groove cross-section describes a circular arc-shape, and a plurality of balls are rollably fitted between the opposing guide grooves in a preloading state. The lower plate and upper plate are integrally machined from a plate-like material and formed in a shape comprising the guide rail portions and guide grooves, and the inner surface of each guide groove is configured as a machined face produced by an end mill. The depth of each guide groove is set to a dimension machinable by a tip semicircular cutting blade portion of an end mill, the rotation axis of which is diagonally set that is no more than 0.146 times the diameter of the balls.
