Changjiang Diamond Laser Welding Core Drill Bit Has Come Out
About The Laser Diamond Core Drill Bit
Diamond bit is the main force of drilling, and its core component is diamond cutter teeth composed of diamond particles and metal powder ratio. Laser welding processing has many advantages in the surface molding of diamond cutter teeth manufacturing due to the processing characteristics of high efficiency, no loss and superior cost performance.
At the same time, in order to improve the drilling ability and efficiency of the bit, the planar structure of the diamond cutter teeth on the bit should be produced into irregular turbine-like morphology.
In the construction process of using diamond bit, due to the harsh working conditions, it is generally necessary to cut the steel bar and concrete at the same time, and the inner and outer edges of diamond cutter teeth are subject to shear force and strong impact force at the same time, so it is easy to lose the cutter teeth and wear the cutter teeth, and the drilling depth is not enough. But through laser welding cutter teeth, can effectively solve the above problems.
Tongling Changjiang diamond adopts laser welding to realize the connection between the matrix of diamond thin-wall drill and the cutter teeth, and the bonding strength is increased by 2~3 times compared with ordinary welding. At the same time, the influence factors of laser welding process and weld microstructure and properties are analyzed. The actual application shows that the laser welded diamond thin wall bit can overcome the problem of cutting teeth, increase the adaptability of working conditions, reduce the cost, improve the adaptability of use, and increase the service life.
