    摘要: An apparatus for abrasive machining has an annular support (1) and a faceplate (5) which is operatively connected to a drive and is mounted on a thrust bearing (2) for rotation in a radial bearing (8). According to the invention, the faceplate (5) has a coaxial bushing (7) journalled in the radial bearing (8), and the faceplate (5) and the annular support (1) are elastically coupled to each other by means of an axle (9) extending through the bushing (7) and biased by a spring in the direction of preload in the thrust bearing (2), the faceplate (5) being connected to the axle (9) for rotation relative thereto by an auxiliary thrust bearing (12) and having on the outer cylindrical periphery thereof a driven member of the drive, a plane (17) drawn through the middle of width of the driven member (16) of the drive extending through a plane (18) drawn substantially through the middle of width of the radial bearing (8 ).
