Inquiry (采购产品): How to make the tip of screw? I am studying manufacturing process. Could you let me know how to make the tip of screw? The tip is so sharp and some tips of screw can be made by closed die forging, right? However, their surface is not so smooth. I am wondering how to make a smooth tip of screw. Thank you. **** Hidden Message ***** Sungchul Joo 30332 USA Company: Georgia Tech E-mail: sungchul.joo@gmail.com **** Hidden Message ***** sungchul.joo@gmail.com
