Abstract
In this paper, we describe an experimental study on working characteristics of coil ends when rotating coil is cut off with abrasive cut-off wheel. The summary of experimental results is shown as follows:
1) Coil can be cut off at higher infeed rate in case of regular revolution and lower revolution.
2) Abrasive wear amount of cut-off wheel increases as infeed rate increases. The increment of the wear becames larger as coil revolution increases.
3) Inclination of coil outside face is within Grade 2 of JIS B2707 in case of low infeed rate (f<10mm/min).
4) Considering the working accuracy, coil had better be cut off with thick wheel at low infeed rate (f<10mm/min) and coil revolution of 40-75rpm. Considering the cost, grade of wheel had better be higher and coil revolution less then 30rpm.
