PURPOSE:To accomplish a smooth fluidization of a mass (mixture of work, grinding material and other working medium to be charged into a barrel) in a barrel by uniformizing vibrations by the same vibration source with the alternation of the spring constant at both ends and at the center of an oval shape in a long-distance circular barrel machining machine. CONSTITUTION:A barrel 3 having opposed semicircle barrels 3a and 3b connected together with linear barrels 3c and 3d parallel in several pairs is supported with numerous springs 2 arranged along the bottom of the barrel 3. In a long-distance vibration barrel working machine of such a type, it is so arranged that springs 2b- 2c, and 2d-2a at both the lengthwise ends of the berrel 3 are made larger in the spring constant than springs 2a-2b and 2c-2d at the center thereof or the springs 2a-2b and 2c-2d at the center thereof are removed and hence, the barrel 3 is suspended with the springs at both the ends thereof. |
