摘要

Apparatus for hardening annular workpieces comprises a hardening unit (2) which can move in the X- and Y-axis direction using a numerically controlled compound table (3), and a unit for rotating the workpiece (1) in the peripheral direction. Guiding supports (7,8,9) are provided for a guiding unit for a drive carriage (12). A rotary drive (13) for the workpiece, a bearing roller (14) for axially positioning the workpiece, an electric motor drive (15) for the carriage and a braking system (16) for the carriage are mounted on the drive carriage.
