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，数控刀头刀粒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, it is necessary to remind you of the unreasonable tool surface damage caused by high temperature grinding (e.g. rough milling).
前涂层，可用于删除所有在原涂层的化学方法。除经常用于复杂刀具 （如滚刀、 拉刀） 或更复杂和镀层的工具有问题工具涂层厚度。化学方法去除涂层通常限于高速钢工具，因为它可以破坏硬质合金衬底︰ 从硬质合金衬底过滤器对钴，涂层的化学去除难多孔、 生气孔和表面涂层。此外，也有适用于去除 PVD 涂层用化学方法申请了专利。
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 the Al 2O 3 deposition layer has the best thermal barrier performance, which ensures the resistance of the blade matrix to plastic deformation during high-speed dry cutting. The golden tin on the surface can reduce friction and provide wear recognition effect. TiCN layer has the performance of anti abrasive wear, which makes the wear resistance of the flank of the blade the strongest.
In addition, CNC cutter head grain recycling tells you that there are other cleaning coating methods, such as laser processing, sanding, and so on. Chemical removal is the most commonly used removal method because it can provide good consistency of surface coating. The typical coating removal tool is through the grinding process in the original coating.
