Manufacturing the solid springs by a synchronous cutting machine with a sheet of cut-off wheel, is available in respect of the working accuracy, but the process is not practical in respect of the productivity in comparison with manufacturing the solid springs by coiling machine. So we try to improve the above productivity by a multi-cut method that the synchronous cutting machine cuts several springs simultaneously with several sheets of cut-off wheel.
As a result of this experiment, the productivity (i.e. volume of abrasive wear and cut-off time), the working characteristics of the solid springs (i.e. free height, inclination of coil outside face, burn mark and step), and cutting condition suited for synchronous cutting of the solid springs with multi-cut method were cleared. It was also cleared that the cut-off time for manufacturing one spring in case of two sheets of cut-off wheel (multi-cut method) decreased by approximately 40-45% in comparison with that in case of a sheet of cut-off wheel while the working accuracy in case of two sheets of cut-off wheel was held the same level as that in case of a sheet of cut-off wheel.
