PVD vs CVD: How to Choose the Right Tool Coating
Why are cutting tools coated? In machining, what is the tool’s coating doing? Peter Zelinski of Modern Machine Shop talks about this with Julius Schoop of TechSolve, the manufacturing consulting firm. The discussion focuses on the difference between physical vapor deposition (PVD) and chemical vapor deposition (CVD). PVD is a line-of-sight coating process allowing for a thinner coating, and therefore a sharper edge. CVD produces a thicker coating more effective as a thermal barrier. In this video, machining passes illustrate the difference between PVD and CVD. Choosing the wrong coating for the cut can dramatically impair the performance of the process. #Machining #MachineShop #Metalworking #ToolCoating #PVD #CVD
