Now-a-days in this competitive era, it is most essential to complete jobs in smallest cycle time in order to achieve maximum profit at minimum wastage. Some leading, printing machine manufacturers outsource some parts from vendors.  Currently, one of the roller sub-assembly is being outsourced from outer vendors. During the visit, we observed that the existing process of manufacturing of such sub-assembly is very lengthy & of manual nature. As to find an alternative solution to the existing problem, we decided to semi-automate the process which will also result in better productivity and which will reduce wastage also. For achieving this, we designed and manufacture an attachment which can be used on a simple lathe machine. Using attachment made the whole process semi-automated, results of which are compared with the previous manual process. It is observed that using attachment reduces cycle time, reduces manpower, also decreases wastage than the manual process.
