Accuracy test of lathe machine and their development in Bangladesh

Abstract

Most of the lathe machines in Bangladesh are not go through the generalized regular accuracy tests. Thus they are not as much as accurate as the manufacturing specification. Because, these lathe machine are not property maintained. To check the accuracy of the exiting machme lools in different area of Bangladesh. We select most common and widely used lathe machine under investigation. Then we select some lathe machine in different geographical location of Bangladesh. Some of them are very old, some are new and some are from different country of origin. Some suitable accuracy test was develop to check the accuracy of the exiting lathe machines. Bed straightness and machining accuracy were measured for different lathe machines. The results are compared with different lathes. According to result it is found that each machine are required proper maintenance to run with high accuracy.
