Specifications

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

  1. Using PDC as its main cutting components;

  2. High wear ability and impact toughness of the PDC;

  3. Improved the drilling efficiency and reduced labor intensity;

  4. The drilling efficiency of pillar model is slightly lower than concave bits, but the abrasion performance is stronger;

  5. For drag bits, compared with the others, this one has a higher abradeability and widely application;

  6. 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

Q:Stainless steel mirror polishing precision casting parts is very difficult, 20
Use the vibrator to polish the material: the high aluminum porcelain 4cm (with a polishing agent that has an automatic mending function), you go find this polish,
Q:What is the casting material?
Commonly used gray cast iron, malleable cast iron, ductile iron, cast steel, etc., non-ferrous metal casting copper alloy, casting aluminum alloy, casting zinc alloy, etc..
Q:In theory, which is more expensive, forging parts or casting parts?
It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
Q:Shandong foundry, casting small pieces of precision casting
Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
Q:What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
Q:How do casting parts remove stress?
Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
Q:Which surface is coarser for cast iron or cast steel castings? Why?
The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.
Q:How to calculate the price of casting parts?
Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
Yantai five God casting is generally 53 yuan /kg, the appearance is quite beautiful
Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
Vacuum casting is the process of using ventilation molds. Molten metal flows into the mold by air pressure, and then removes air to form a vacuum. The casting process is mainly used for small parts or jewelry with exquisite detailsCompared with the traditional clay sand casting, heat hardening resin sand casting production with low surface roughness, high precision, good quality characteristics, dimensional accuracy of resin sand mold after hardening with good rigidity and high, and not easy to deform, so in the choice of process parameters, mechanical processing you can select a smaller margin, thereby reducing the consumption of metal solution and machining cost, which can improve the dimensional accuracy of castings.
