Summary:
The utility model discloses a PCD cutter particle, which comprises a tungsten steel cutter body, a cutter particle hole, a screw groove, a polycrystalline diamond blade, a welding groove, a tool nose R angle, a first oblique row plate, and a second oblique Row plates, flutes, upper baffles, side baffles, welded bottom plates and welded side plates. The utility model has the beneficial effects that the polishing precision and the fineness of the knife particle to the outer casing of the mobile phone are improved; the first and second oblique row plates of the polycrystalline diamond blade are provided with a plurality of chip flutes at equal intervals, 1. The second oblique row plate is symmetrically arranged, which greatly improves the chip removing effect of the knife grain on the outer casing of the mobile phone, and the chip flute pattern can effectively avoid scratching the processed surface and ensure the knife The high quality of the grain polishing and the cleanliness of the use; the tungsten steel body has several layers of spiral groove in the granule hole, which makes the knives more securely connected to the CNC spindle; the PCD knives have functions Diverse, use more secure features.
