From the most high-grade raw material, they manufacture shock absorber and provides a smoother ride for the customer while driving. Shock absorber they manufactured is very efficient in performance. They improve the durability of the shock absorber by plating them chrome and nickel to prevent corrosion. The casting part of shock absorber body is imported. While machining on the casting body of shock absorber different defects occurs. Due to this many components were rejected. Causes due to which component was defected are milling width oversized and m6 tapping. In our research, we find some remedies to overcome these defects which occur during the machining processes. To overcome from defect of milling width oversized we are going to provide coolant arrangement in the current industry locator design. And to overcome from second defect M6 Tapping we are going to provide coolant arrangement in current drill tool. So, in this way, our project aim is to overcome these two defects and improve the production rate of the company by eliminating occurring defect due to machining.
