PVD Vs. CVD—How To Choose The Right Tool Coating

By June 3, 2019 No Comments

In the second video, “PVD vs. CVD—How to Choose the Right Tool Coating,” the team works to demonstrate how the correct tool coating could dramatically increase the efficiency and effectiveness of the machining process. Tool coatings are important in the machining process because they provide a level of lubrication and protection against craters in the material, weak and uneven patterns and erosion of the tools.

PVD, or physical vapor deposition, is a line-of-sight coating process which allows for thin coatings and sharp edges. CVD, on the other hand, stands for chemical vapor deposition and is thicker to protect against heat. PVD is typically applied to finishing tools, whereas CVD proves best for roughing. Utilizing the correct tool coating protects the tools and materials for best results of the process.
