냉간 단조용 펀치의 TiN 코팅처리에 따른 자동차 베어링축의 표면 영향에 관한 연구
Effect of TiN-Coating on a Punch on Surface Quality of a Cold Forging Automotive Bearing Shaft
초록
In this paper, effect of TiN-coating on product quality such as dimensional accuracy and surface roughness is experimentally investigated. A punch of SKD11 material in cold forging of an automotive bearing shaft and its related process found in a cold forging company ate selected as the test example. The effect of TiN-coating is revealed in a quantitative manner. It is to be noted that TiN-coating is effective in controlling the dimensional accuracy and surface roughness as well as in increasing tool lift.
