The forward and back centers, and also different flood devices treat number of the main devices used when processing shaft and pipes. In case of processing of the nonrigid shaft characterized by the big relation of length to diameter it is necessary to apply the lunettes warning a deflection of the processed details under the influence of forces of cutting and a body weight or supporting the end of a shaft at its console fixing in the boss of the machine.
Development of high-speed methods of processing reasonable caused improvement of the designs of all called above adaptation. Instead of the usual motionless centers the centers equipped with solid alloy, and the improved designs of the rotating centers were widely used; during the work on the adjusted machines "the floating centers" are used, allow to establish details to an axial emphasis. Ordinary screw buckles are replaced with new designs of high-speed flood devices. Also designs of lunettes are improved.
The motionless back centers work as sliding bearings with big specific pressure, are exposed to strong heating and wear. For this reason the centers made from tool carbonaceous by staly are not suitable for processing on are high speeds.
The center is persistent. Morse No. 2,3,4,5,6 cone
