PCT No. PCT/FR96/01545 Sec. 371 Date Mar. 31, 1998 Sec. 102(e) Date Mar. 31, 1998 PCT Filed Oct. 6, 1996 PCT Pub. No. WO97/13614 PCT Pub. Date Apr. 17, 1997A device for measuring and/or checking the diameter of a cylindrical part (2) moving orbitally about an axis (3) during a grinding process. The device comprises a measuring head (7) coupled to a holder (18, 22) which is provided with a member (26) for engaging the circumference of the part (2), and is movably mounted in a direction parallel to itself on a frame (31) so that it can follow the orbital motion of the part (2). Grinding is performed by means of a tool (1) moving transversely to said axis (3), and the frame (31) is moved transversely to said axis and synchronised with the motion of the tool (1).
