Structure and characteristics of diamond drill bit

图片
Structure and characteristics of pdc diamond dill bit overall structure The  diamond material bit is a one-piece bit. The whole bit has no moving parts, mainly including bit body, crown part, hydraulic structure (including water hole or nozzle, water tank, also known as flow channel, chip chute), diameter protection and cutting edge (tooth). The crown of the diamond drill bit  is the working part of the bit cutting rock. Its surface (working face) is provided with cutting teeth of diamond material and arranged with hydraulic structure. The drill bit body is a steel material body. The upper part is connected to the drill string and the lower part is connected with the crown tire body (the steel crown is integrated with the drill bit body). The hydraulic structure of diamond bits is divided into two categories. A type of natural diamond drill and TSP drill, in which the drilling fluid flows out of the central water hole and disperses across the surface flum...

Dressing skills of grinding wheel

Dressing skills of grinding wheel Sharpening is a process of sharpening a superhard abrasive grinding wheel. In this process, a sharp cutting edge needs to be formed in addition to the binding agent between abrasive particles and the abrasive wheel abrasive grains which are blunt, so that the abrasive grains with strong grinding performance can stand out the binding agent. Sharpening must also remove minute materials from the pores on the surface of the grinding wheel to prevent the increase of grinding force on the grinding wheel. The increase of grinding force on the grinding wheel will cause vibration and burn on the surface of the part. Without proper sharpening, it is impossible for even the best grinding wheel to obtain high quality and dimensional consistency for the machined parts. In fact, when you invest in high-quality grinding wheels, it's important to trim them well in order to achieve high grinding performance. Shaping can be said to be a part of the ...

Application of Nano Diamond

图片
  Application of Nano Diamond 2020.10.09 More SuperHard Products Co., Ltd 3 Nano-diamond is a kind of artificial diamond material with extremely small particle size, spherical or nearly spherical shape, with a particle size of 0.5-10nm, with an average of 4-5nm, and most of the particle size distribution is 2-8nm.   Nano-scale diamond not only has the excellent characteristics inherent in diamond, but also has the peculiar properties of nano-materials. Nano-diamond has been developed more than 30 years ago, but its application was limited to the field of polycrystalline, polishing agent and other abrasives. With the deepening of people ’ s understanding of the properties of nano-diamond, nano-diamond has been used in lubricants. , Metal coating, magnetic recording systems, medicine and other fields began to gain applications, and the application areas are still expanding.     The application of nano-diamond in lubricating oil, grease and coolant is mainly used in mac...
