CVD Diamond Coating Services

The need for CVD diamond coated cutting tools continues to grow. Driving this growth is the use of composites within the Aerospace, Automotive, and other industries. In order to have a Best of Breed cutting tool used to machine carbon fiber reinforced plastic (CFRP) or other composites, there must be a clear understanding of each application. The machining function, the material, and the goals of the operations all must be considered on a case by case basis in order to provide a top performing CVD coated cutting tool. Since the cost of machining errors and scrapping material is very expensive, a top performing tool is defined as not only a tool that last the longest, but a tool that performs with consistency. End users do not plan for the best case, but the worst, so a consistent wear rate in addition to extended wear is critical to providing a Best of Breed CVD diamond coated cutting tool. The coating of cutting tools with CVD diamond is a very complex process with many variables that must be optimized and tightly controlled in order to consistently deliver extended wear rates. At SP3 we have spent over 100 man-years of R&D optimizing coating variables and developing tight process controls.
