The Significant Difference between Nanocrystal and Microcrystal CVD Diamond Coating Technology-En
Nanocrystal coatings are smooth, dense, and feature a low coefficient of friction, reduced cutting resistance, and lower cutting heat, resulting in superior surface finish and faster cutting parameters (S, F).
Compared to microcrystal diamond coating, tool life of nanocrystal diamond coated tool is significantly extended.
Nanocrystal-coating costs are approximately 50% higher than microcrystal coatings. For example, using a standard D6 * 65 end mill, the cost increases by about $3 per tool.
Breakthrough in Graphite Machining: Ultra-Long Diamond-Coated End Mills
Addressing coating difficulties in 10×-diameter ultra-long end mills (10×diameter length) for graphite electrode machining, this study introduces dynamic pressure-compensated fixtures and gradient multi-stage deposition. By applying 5-8 diamond layers (5-10μm per stage) with stress-relief annealing, the solution resolves adhesion and thermal distortion issues in 10×-length edges, achieving 10× longer tool life for high-performance graphite electrode production.
