The rolling process used to produce tricone bits
The rolling process used to produce tricone bits
The tricone drill bit is integrated, the whole bit has no moving parts, the structure is relatively simple, with high strength, high wear resistance, and impact resistance is one of the worlds in the 1980s three new drilling technology. It has the advantages of fast speed, more footage, long service

The installation of the tricone bit
In industrial production, the tricone drill bit is widely used. At high speed, the tricone bit can accumulate the power to break up the hard rock, resulting in a significant increase in drilling speed. And tricone bits for a variety of rock formation topography structures are more suitable, in the o

How to resolve some of the issues during the use of reamers?
In machining, reaming hole machining is often encountered. Because the number of teeth of the reamer is more, the guidance performance is good, the diameter of the heart is large, the rigidity of the tool is good, the processing margin is less, the thickness of the chip is thinner, can obtain higher

The working principle of the hole opener
The working principle of the hole opener is relatively simple: in the ordinary hole opening mode, it is the same as the hand drill, the motor drives the gear drive, the gear drives the rod rotation, which in turn drives the drill rotation so that the hole opener can complete the drilling work, this
