This application sets up the weld zone simultaneously on the tool bit, and the one end of weld zone and transition layer forms one deck welding layer on the tool bit, and this welding layer is used for the fixed of tool bit, avoids using end stage to have partial tool bit surplus, improves the tool bit utilization ratio. A transition layer is arranged between each working layer, the bottom of each transition layer and a welding area are integrated, the sintering strength of each layer is tightly enhanced, the connection strength between the working layers of the tool bit is increased, and the tool bit is not easy to crack. The structure supports integral forming and improves the manufacturing efficiency of the cutter head.
In some embodiments, the ratio of the area of the working area to the bonding area is (80: 15) - (85: 20). Set up work area and welding area under this proportional relation, when can effectively prevent that the saw bit from droing, realize the maximize that the tool bit utilized.
In some embodiments, the transition layer is integral with the bonding region. Because the transition layer and the welding area are made of the same material, the connection between the sintered transition layer and the welding area is tighter to form a whole, so that the working layers clamped among the transition layers are tighter and are not easy to crack.
In some embodiments, the ratio of the total thickness of the first working layer, the total thickness of the second working layer, and the total thickness of the transition layer is (40-50): (26-32): (30-39). The first working layer plays a main cutting role and occupies the greatest total thickness of the cutter head; the contact surface of the second working layer and marble is less prone to generating loss than the first working layer, a chip removal channel is added on the surface of the cutter head, and the chip removal cutter head capacity is improved; the transition layers are more in number and exist among the working layers, loss can be generated firstly in the using process due to the fact that the transition layers are thinner, depressions are formed beside the working layers, and sharpness of the working layers is improved
