The purpose of this study is to develop the automatic manufacturing system for producing a phosphor bronze wire. Automatic continuous manufacturing system is necessary to raise the productivity and strengthen the competitiveness in the phosphor bronze wire manufacturing. For this purpose, the authors carrying out the design and production of devices such as raw material supply, drawing, heat treatment, winding and main control system, etc. As a result, we could product the 0.35mm of phosphor bronze wire with continuous processes.

In this study, development of the manufacturing system for the oriental medicine needle was carried through the wire drawing from the wire supply, straightness, heat treatment and surface treatment processes, and finally wire cutting or winding by the online process. As a result, a prototype manufacturing system for the oriental medicine needle wire has been developed. It has been shown that all development targets, such as, straightness, precision, surface roughness, tensile strength, discoloration, noise, diameter range and maximum production speed have been satisfied through the performance test.

Wire manufacturing system is consist of several parts performing such as feeding, drawing, straightening, heat treatment, surface finish and winding. Drawing and straightening processes are repetitive tasks and the most of the them are performed discretely. In this study, automatic manufacturing system for medium fine straight wire has been developed. The developed system is operated with continuous processes, so decrease the time cost and increase product quality
