PURPOSE:To improve machining efficiency ever so better, by locking a pair of clamp members to the tip end of a paired reciprocating member rotating together with a couple of turning members in one, while performing the injection machining of a work held by these clamp members in between under pressure as being rotated and vibrated at high speed. CONSTITUTION:Air is made to flow in a second opening hole 26b from an arrow G direction, flow inside a hollow chamber 20a by way of a second interconnecting hole 21e, and a reciprocating member 16 is pressed toward an arrow H, shifted to a most left end position whereby a work W is held by a pair of clamp members 17 in between under pressure. Next, a paired turning member 15 is rotated by a motor via a sprocket 29 and the work is also rotated via these clamp members 17, while an impeller is rotated by the motor via a belt 9, and a shot is sprayed to the work, thus efficient injection machining takes place for the work. |
