摘要： An abrasive apparatus adopted to abrade a curved surface of workpiece includes: an abrading head including an abrading tip having a substantially spherical outer surface and a rotating shaft supporting the abrading tip, the abrading head being positioned to face the curved surface; a thrust moving mechanism for relatively moving the abrading head and the curved surface; a lateral moving mechanism for relatively moving the abrading head and the curved surface; a pivotal moving mechanism for relatively moving the abrading head and the curved surface pivotally around a center point; and a controller for controlling the abrading head, the thrust moving mechanism, the lateral moving mechanism and the pivotal moving mechanism synchronously so that the abrading tip contacts and presses the curved surface at any point thereon with a substantially constant pressure in a direction consistent with a normal line thereat. An angle adjuster supporting the abrading head for adjusting an angle of the rotating shaft against the curved surface is also disclosed.
