<p>The arrangement consists of a suction pump (16) which is connected by a suction line (18) to an inlet opening (20) which is positioned close to a machining operation. The arrangement sucks the machining swarf and debris into the suction line from which it is filtered out. The air, which has been sucked-in by the pump, is fed back via a line (32) to a blow jet (34) which is near the machining operation. The feed-back line incorporates a valve (36) which can let-off some of the recirculated air. The blow jet is directed so that it will blow the machining swarf into the suction opening.</p> |
