Thread Rock Drill Button Mining Bit Matched with Rod

Product Description

Type of Bit:

Head Diameter:40 mm -200 mm (D)
Bit Type:Button Bit, Cross Bit
Button Type: Semispherical Button, Ballistic Button, Conical Button
Thread:R25, R32, R38, T38, T45, T51(T)
Bit Body:Standard Skirt, Retrac Skirt
Bit Face:Flat Face, Concave Face, Convex Face, Drop-Center Face
Material:High quality tungsten carbide

The selection of Bit Face Type:

Drop center face bit:    

It has high penetration rates in soft to medium hard and fissured rock formation, and has better hole deviation control.

Concave face bit:

It’s suitable for medium hard and similar rock formations, it has good hole deviation control and good flushing capacity.

Convex face bit:                                                                                

It has high penetration rates in soft to medium-hard rock formation. It has the best performance of resistance to steel wash, and reduce the load and wear on the gauge buttons, but it has poor hole deviation control.

Flat face bits:  

It’s suitable for hard to very hard and abrasive rock formations.

The selection of Bit skirt:

Standard skirt:                                      

This design is suitable for most of rock formations.

Retrac skirt:  

This type design can get better hole deviation control while drilling, it can get bit back easily while the bit is jammed during drilling.

Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.
Q:How much is the casting allowance in the design of the casting machine and the drawing?
The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.
Q:Why do cheap cars like stamping parts instead of casting parts?
We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.
Q:How to distinguish the forging parts and casting parts accurately
To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.
Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?
according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
Q:How can the casting be quenched and tempered?
Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:
Q:What is the reason for 304 stainless steel precision casting parts to be changed?
Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks
Q:Where is the precision casting factory?
Everywhere is. Look what you want to do
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:Explain the heat treatment effect of casting parts, forging parts and welding parts
2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
