Abstract

Tanjung Maintenance Sdn Bhd is one of the native companies that produced maintenance service for heavy industry equipment. Among maintenance services in Tanjung Maintenance Sdn Bhd are ball valve polishing, valve seat lapping process, hydro test and many more. Tanjung maintenance firm they were still using traditional method for polishing process. The old method is risky to the workers and it limited to certain ball, which are not suitable for large and too small ball. The old method using expelled steel to grip the ball and the lathe machines as the medium rotation of the ball. Since from the problem, a recommendation had been made to design s special jig that flexible to grip a different sizes of ball and construct the technique more users friendly to the human resources especially workers. A detail revision and analysis on traditional technique has been done. .It is important to develop an assistive jig, which is that have fully criterion to work out the problem. Hopefully the concepts that have been generated can diminish an accident to the workers and can reduce the cost of polishing process..
