Spherical turning attachment

Submitted in partial fulfilment for the requirement of the degree of Bachelor of Engineering in MechanicalSpherical Turning Attachment: On lathe machine it is not possible to manufacture spherical\ud objects but with the help of spherical turning attachment it can be easily manufacture. Earlier the\ud spherical objects were made by various processes like annealing, wire drawing, cold forging,\ud flashing, heat treatment, grinding, lapping etc. but this process were tedious, time consuming and\ud comparatively cost of this process is high.\ud The movement of tool post on normal lathe machine is restricted in only two directions, by\ud replacing the tool post with spherical turning attachment the rotating motion can be achieved of\ud about 360o. The machine named ball turner which is available in the market for manufacturing\ud spherical objects cost very high
