摘要： A method for shanking a rock bit (15) utilizing a shank locator (21) and a cone locator (23), each with tapered surfaces to engage respectively the tail stock of a lathe and the cones (17) of a rock bit (15), to accurately align the body and the cones (17) of the bit (15) concentric with the design centerline of the bit. The lathe and cone locators each have interior conical surfaces to assure accurate, coaxial alignment of the shank end (13) and the cone end of the bit (15). A compensating chuck is used to grip the cone end of the bit body and firmly hold the normally uneven surfaces while the threads are being machined.

摘要： The invention relates to a high-precision revolving centre (10) for machine tools.
Prestressed bearings 40 and 45 are brought into abutment on the one hand against internal 33 and external 25 cylindrical surfaces whose deviation, at any point on the surface, with respect to the theoretical surfaces centred on the axis, is less than 1 µm, and on the other hand against reference surfaces 26 and 34 perpendicular to the axis. Threaded elements 50, 55 enable the bearings 40, 45 to be stressed. Once the centre to has been assembled and the bearings stressed, the revolving centre is mounted on a grinder in order to give a precision finish to the tip 90, the concentricity reference surface 91 and the perpendicularity reference surface 92.
Application to the manufacture of very high precision parts.

The tailstock portion (4) comprises a rotatable tailstock support (112) having at least one workpiece seating surface (117). The tailstock includes a centering locator guide (114) extending axially from the tailstock support (112) and having a generally curved outer surface (115) for centering the workpiece in the chuck (2). The tailstock portion (112) also comprises an outwardly flaring housing cover (118) including an end flange (124) and sealing means (126) whereby relative axial movement of the tailstock (112) toward the chuck (2) provides for the cover (118) to fit over a workpiece mounted in the chuck with the sealing means (126) contacting a surface of the workpiece radially inward of that portion of the workpiece being machined. The sealing means (126) preventing the introduction of contaminants into the workpiece (6) and chuck (2) and also providing for dampening of vibrations from the machining process.
