Abstract
In this paper, we describe an experimental study on the cutting off characteristics of continuous coils with the especially designed synchronous cutter during coiling. The summary of experimental results is shown as follows:
(1) Abrasive wear amount of cut-off wheel increases exponentially to the infeed rate.
(2) Mean cut-off force and abrasive wear anount are in proportion to the power of abrasive infeed rate.
(3) The less abrasive infeed rate is, the better working accuracy of coil ends is. And so taking a view of cost and coil working accuracy, optimum abrasive infeed rate is≅5.0mm/min.
