在钻头或铣刀铣削过程中，研磨切削刃是需要删除原来的涂层，因此砂轮必 须有足够的刚度。刃口磨预处理是至关重要的不仅要确保在磨的原始的切削刃几何保留形状是完全准确的并要求的PVD涂层刀具重磨后的工具必 须是"安 全"。因此，数控刀具刀片回收提醒您必 须避免不合理的磨削加工过程(例如︰高温导致粗磨或干铣削的刀具表面损伤)。
In the process of bit or milling cutter milling, the original coating of grinding cutting edge needs to be removed, so the grinding wheel must have enough rigidity. Edge grinding pretreatment is very important, not only to ensure that the original cutting edge geometry in grinding is completely accurate, but also to require PVD coated tools to be "safe" after regrinding. Therefore, NC tool blade recycling reminds you that you must avoid unreasonable grinding process (for example: high temperature leads to rough grinding or dry milling tool surface damage).
Pre coating can be used to remove all chemical methods in the original coating. In addition to often used for complex tools (such as hobs, Broaches) or more complex and coated tools, there are problems with tool coating thickness. Chemical removal of coatings is usually limited to high-speed steel tools, because it can destroy cemented carbide substrate: cobalt is removed from cemented carbide substrate filter, and the chemical removal of coatings is difficult for porous, gas hole and surface coating.
In addition, some chemical methods for removing PVD coating have been patented. In these chemical removal solutions and cemented carbide substrates with only slight reaction, but these methods are not extensive. By using gradient sintering technology, the impact resistance and wear resistance of the cutting edge are enhanced, so as to improve the anti damage ability of the cutting edge.
Carbide with special crystal structure improves the red hardness of the blade matrix and enhances the high temperature resistance of the blade. The special structure of Al 2O 3 deposition layer has good thermal barrier performance, which ensures the resistance of the blade matrix to plastic deformation during high speed dry cutting. Gold Tin on the surface can reduce friction and provide wear recognition effect. The TiCN layer has the property of anti abrasive wear, which makes the wear resistance of the flank of the blade strong.
In addition, CNC tool blade recycling tells you that there are other cleaning coating methods, such as laser processing, sanding, and so on. Chemical removal method is commonly used to remove surface coatings because it can provide good consistency. The typical coating removal tool is through the grinding process in the original coating.
