4 wing pdc drag bit mining drill bit from manufacturer
Wear resistance pdc tooth
Bit size: 75~270mm
Long service life

Description :

Application	Used for penetrating the degassing hole, drainage hole, and grouting hole of coal mine.
Chracteristics	Using PDC as its main cutting components; High wear ability and impact toughness of the PDC; Improved the drilling efficiency and reduced labor intensity; The drilling efficiency of pillar model is slightly lower than concave bits, but the abrasion performance is stronger; For drag bits, compared with the others, this one has a higher abradeability and widely application; Widely used in warious of different fields, mining, hydrology, subterranean, piling and water well drill.
Formations	Available in a variety of sizes to accommodate drilling in a variety of formations, from sand and clay to shale, limestone, gravel, and more. f<6.
Advantage	1. With 15 years production experience; 2. With standard management and strict quality control system, we have got ISO9001:2000 Certificate and API Certificate; 3. Our PDC drill bits have been widely sold to many countries, such as Australia, Turkey, Russia etc.; 4. As per your requirments/ samples/ drawing, we can design and produce the specified specification.

Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump: Buffing should be better, to see how your embryo, but a bit difficult

Q: Why does the precision casting factory not usually make iron castings?: Jiangyin Lin Xing stainless steel (precision manufacturing) Co., Ltd. to provide professional precision casting

Q: What are the requirements for casting steel castings?: 4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface

Q: In theory, which is more expensive, forging parts or casting parts?: The structure of the casting is relatively flexible in design, and the modeling is easy to realize.

Q: Casting parts have poor surface finish. What sand is used to make them?: V casting, EPC, precision casting of the surface is good.

Q: What do you mean by "proofing" in the casting? Do you charge for the proofing?: Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me

Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!: Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over

Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle: Processing stainless steel materials, you can use YG class tools, such as YG8, YG8N. The tool geometric parameters g0=15 degrees to 18 degrees, a0=6 degrees to 8 degrees, kr=75 degrees, ls=-5 degrees to -8 degrees; cutting amount is Vc=43 m/min, ap=0.3 to 0.5 mm, f=0.16mm/r.

Q: The difference between sheet metal and casting parts: Casting parts are made by casting (followed by a variety of processing), the shape can be simple, can also be very complex, usually large parts, as a base, bed, work table, and so on, good seismic performance.

Q: ZGMn13 casting parts processing, with what knife head good?: The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger, its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try
