SPVD TN
is a sort of coating with gold yellow color.
SPVD TN coating has high hardness, good wear resistance and proper oxidation resistance. It is suit for high speed cutting. SPVD TN has high performance/cost ratio. It is generally used to prolong the lifetime of the cutting tools, especially for the cutting tool used to cut the soft products like brass and low carbon steel. SPVD TN can be deposited onto lathe cutter, milling cutter, drills, screw tap, gear hobber, forming moulds, press dies, extrusion dies and die-casting moulds, parts of moulds, wear resistance parts, mechanical parts, decorative parts.SPVD TN is the best choice for cutting iron products, plastic forming moulds and wear resistance products.
