Abstract

DC 60 (01/10/42) Grinding machine (10), specifically a grinder for removing material from the end surfaces of workpieces (28), which consists of a rotaryly driven machine tool (35), a clamping device (27) for holding the workpiece relative to the rotaryly driven machine tool (20,21) for creating relative displacement between the workpiece (28) and the rotaryly driven machine tool (35) for more precise grinding. The grinding machine (10) also consists of a tubular cylindrical frame (13) that extends around a longitudinal axis. This frame has an inner longitudinal cylindrical region (14) that extends from one end of the frame. In this inner cylindrical region, there is a longitudinal axis that extends horizontally from the longitudinal axis of the frame (13). A shaft (17) is positioned in this inner cylindrical region (14) for creating angular displacement within this region. The shaft is provided with a groove, the motor(25) is provided in the groove, the shaft(26) is coupled with the motor(25) and works in conjunction with the clamping device(27) to hold and rotate the workpiece(28), the rotating outer frame(15) is enclosed along the edge of the tubular cylindrical frame(13), the cover assembly(30) is firmly attached to the outer frame(15) and extends radially around one end of the tubular cylindrical frame(13) in such a way that the inner surface(33) of the cover assembly is pressed against one end of the frame, the rotating driven machine tool(35) consists of an abrasive ring area bearing the inner surface(33) of the cover assembly(30), and the shaft(17) is provided. In the inner region (14) such that, when the shaft causes an angular displacement within the inner region, the workpiece (28), which is held in place by the clamping device (27), is moved toward and in contact with the annular region of the abrasive material. The abrasive (10), specifically the grinder for removing material from the end surface of the workpiece (28), consists of a rotaryly driven machine tool (35), a clamping device (27) for holding the workpiece relative to the rotaryly driven machine tool (20,21) for causing a relative displacement between the workpiece (28) and the rotaryly driven machine tool (35) to achieve more precise grinding. The abrasive (10) also consists of a tubular cylindrical frame (13) that extends around a longitudinal axis, which has an inner longitudinal cylindrical region (14) extending from one end of the frame. This inner cylindrical region has a longitudinal axis. Extending horizontally from the longitudinal axis of the frame (13), a shaft (17) is positioned in the inner region of the cylindrical shape (14) for the purpose of creating an internal angular displacement. This shaft is provided with a motor groove (25) which is fitted into the groove. The shaft (26) is coupled with the motor (25) and works in conjunction with the lathe clamping device (27) to hold and rotate the workpiece (28). A rotating outer frame (15) encloses the rim of the tubular cylindrical frame (13). A cover assembly (30) is firmly attached to the outer frame (15) and extends radially around one end of the tubular cylindrical frame (13) in such a way that the inner surface (33) of the cover assembly is fitted to one end of the frame. The rotary driven machine tool (35) consists of a circular region. The ring of abrasive material bearing the inner surface (33) of the said cover assembly (30) and the said shaft (17) are arranged in the said inner region (14) in such a way that when the said shaft causes an angular displacement within the said inner region, the said workpiece (28) held by the said clamping device (27) is caused to move toward and come into contact with the said annular region of the abrasive material.
