Description

Technical Field

[0001] The utility model relates to the technical field of tool coating equipment, in particular to a clamp for tool PVD coating. Background Art

[0002] Coated tools are prepared by coating a thin layer of refractory metal or non-metallic compound with good wear resistance (it can also be coated on superhard material blades such as ceramics, diamonds and cubic boron nitride) on the surface of a cemented carbide or high-speed steel (HSS) substrate with good strength and toughness using a vapor deposition method. The coating acts as a chemical barrier and thermal barrier, reducing the diffusion and chemical reaction between the tool and the workpiece, thereby reducing the wear of the substrate. Coated tools have the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, low friction coefficient and low thermal conductivity. When cutting, the life of uncoated tools can be increased by more than 3 to 5 times, the cutting speed can be increased by 20% to 70%, the processing accuracy can be increased by 0.5 to 1 level, and the tool consumption cost can be reduced by 20% to 50%.
