2. In fact, all Philips cutter heads have automatic sharpening function. This is the patent of its rotary cutter head. Philips is expensive because the quality of the cutter head is not generally good, and the patented technology has great advantages, which also limits the competition of other brands, which is also the reason why other foreign brands have not rotated.
At present, Philips cutter heads are all imported products, which are ground by computer, and the cutter heads have a very high degree of fit with the supporting net cover. Therefore, when using the cutter head, it is necessary to pay attention to: when disassembling and cleaning the cutter head by yourself, do not detach the cutter head from the tool holder, and just rinse the tool holder directly. If you want to remove the cutter heads, you must be careful not to confuse each rotating cutter head with its own mesh cover. Although the patented rotary cutter head has a self-sharpening effect, the grinding effect after mixing may be slightly worse. If it breaks down, it will be expensive to buy another one.
