| Why Are So Many CNC Tools Gold, Black, Blue, or Purple? | 为什么这么多数控刀具是金色、黑色、蓝色或紫色的？ |
| The colour isn’t just about appearance. Modern cutting-tool coatings can improve: 🔹 Wear resistance 🔹 Heat resistance 🔹 Cutting performance 🔹 Tool life 🔹 Productivity Common coating families include TiN, TiCN, TiAlN/AlTiN, and other advanced multi-layer coatings. The best coating depends on the application. A coating that performs exceptionally well on hardened steel may not necessarily be the best choice for aluminium or other non-ferrous materials. Tip: Don’t choose a coated tool simply because the coating looks impressive. Match the coating to the workpiece material, cutting speed, temperature, and machining operation. The right combination of substrate + geometry + coating + cutting parameters is what delivers performance. #CoatedTools #CarbideTools #CNCMachining #CuttingTools #ToolLife #Manufacturing #PrecisionEngineering HD Image 1: Studio photograph showing carbide cutters with different coating colours.
