What Are The Factors That Determine The Degree Of Wear Resistance Of Pick-toothed Alloy?

1. The proportion of alloying components is a vital element in the wear resistance of this selection.
2. Hardness is the capability of the support material to keep high-temperature hardness. In cutting coal stone knives, the surface of the cutter head is 600-800 ° C, that the hardness drops by roughly 50%, and also the material calms and moisturizes the worn teeth.
3. Welding residual pressure. There's a large tensile strain involving the brazing filler metal and the base material, which leads to a drop in the weld power, a powerful cutting force brought on by the impact load, along with an embrittlement of the cemented carbide head.

Classification Of Drilling Tools

1. Reaming drill. Reaming drills have 3 to 4 teeth and are more rigid than twist drills to expand existing holes and improve dth drilling tools accuracy and finish.  2. Drilling. The boring drill has a large number of teeth, and the hole end is processed into a desired shape by a forming method for processing of dth drilling tools factory the countersunk holes of various countersunk screws or flattening the outer end faces of the holes.  3. Center drill. The center drill is used for drilling the center hole of the shaft type workpiece. It is essentially a composite of twist drill and boring drill with a small helix angle, so it is also called a composite center drill. 4. Twist drill. It consists mainly of the working part and the handle. The working part has two spiral grooves that are shaped like twists. In order to reduce the friction between the guiding portion and the wall of the hole during drilling, the twist drill is gradually reduced in diameter toward the shank an

How To Deal With PDC Drill Bits Mud Pack Phenomenon

图片
Let the  top hammer drilling tools factory  tell you the solution when the PDC bit has a mud pack phenomenon! 1. The first principle of dealing with bit mud packs is: don't rush to drill, because the more packaged, the more powerful. 2. Regardless of the prevention or treatment of the bit mud pack, it is inevitable to adjust the mud performance. It is found that the PDC drill bits have signs of mud pack, and the drill should be stopped immediately and the detergent should be disposed in the well at the first time to clean the drill bit. 3. Stop drilling, increase displacement and enhance the effect of hydraulic flushing. Lift the drill bit off the bottom of the well, increase the rotational speed and increase the centrifugal force to make the mud block easy to pull out, and move it up and down a few times, then press down to the bottom of the well. Cycle for 5-10 minutes, repeat the above process; if it is invalid within 2 cycles, you should consider drilling. We specializ
