The centreless cylindrical grinding machine for grinding of bar-shaped workpieces and method for a centerless cylindrical grinding of bar-shaped workpieces

摘要

In the case of a machine for a centerless cylindrical grinding when the workpiece (1) in a grinding gap (15), which by means of the regulating wheel (3), the grinding wheel (5) and the supporting straightedge (7) is formed. The regulating wheel (3) rotates about its axis of rotation with the direction of rotation (11) and thus drives the workpiece (1) in the direction of rotation (13) for rotation on. The grinding wheel (5) is used for the rotation about its axis of rotation (6) with the direction of rotation (12) driven. The workpiece (1) runs in the direction of its longitudinal axis a plurality of sets of regulating washers (3) and grinding wheels (5), each of which are arranged one behind the other coaxially. As a rule is - and grinding wheels (3), (5) have on their axes axial spaces; in this case, the regulating washers (3) in the intermediate spaces between the grinding wheels (5) and vice versa, so that lateral covering regions (19) between the disks (3), (5) are formed. As a result, there is a downwardly displaced grinding gap (15), of the downwardly widened and a secure support of the workpiece (1) to the rule - and grinding wheels (3), (5) ensures. A common reference plane (14) and the enclosure triangle (21) show the advantages of this application, to clearly. Even workpieces (1) of a small diameter are displaced downward, in which, after grinding gap (15) is clamped securely, so that with a high volume of chips can be ground.
