METHOD AND ROUND GRINDING MACHINE FOR CENTERLESS CIRCULAR GRINDING

摘要

The invention relates to a method and a cylindrical grinding machine for centerless cylindrical grinding. According to the invention, the workpiece is supported on a first contact surface (7) and a second contact surface (9). The first contact surface (7) and the second contact surface (9) are arranged at an angle to each other in the manner of a prism. The grinding disk (3) is applied to the workpiece (1) with a certain application force F, whereby the workpiece (1) in turn is pressed into secure contact against the first contact surface (7) and the second contact surface (9). The two flat contact surfaces (7) and (9) cause braking of the workpiece (1), which is rotationally driven solely by the grinding disk (3). The braking reduces the rotational speed of the workpiece (1), such that the grinding disk (3) causes grinding in addition to the rotational driving of the workpiece (1). The workpiece rotational speed can be precisely set by means of an additional brake (11), which applies an adjustable braking force P to the workpiece (1).
