There are many types of bullet teeth, and the general structure is to inlay a carbide tip in a low-alloy structural steel body that has been quenched and tempered. The bullet teeth are subjected to high periodic compressive stress, shear stress, and impact load during work. The main forms of failure are the tool tip falling off, chipping and tool tip and tool body wear. Under certain working conditions, the cutter body is often broken and the teeth fails. Since the mechanical properties of the teeth body directly affect the service life of the teeth, the material of the teeth body and the effective heat treatment method are selected reasonably.
Bullet teeth types:
- Classic series: for soft rock
- Cemented carbide strip series: for strongly weathered sandstone and mud stone
- Cemented carbide button series: for strongly weathered sandstone and mud stone
- Plasma welding ripple series: for medium hard rock and hard rock
- Lengthened series: for silt
- Large body series: for cobblestone
- Upgraded series: for hard rock, such as granite and basalt
For consumers, the longer the bullet teeth are used, the higher their satisfaction. Reasonable design and high-quality materials are the key to ensuring the service life of bullet teeth. This requires bullet teeth manufacturers to select materials carefully and strictly control to ensure that the wear resistance and impact resistance of the produced bullet teeth meet the relevant national requirements. At the same time, the welding materials and the auxiliary materials used for heat treatment, Must match the bullet teeth material.
