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: Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?: Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting. General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.

Q: Explain the heat treatment effect of casting parts, forging parts and welding parts: Good welding of low carbon steel (alloy), probably because the weld workpiece rigidity, fast cooling, the weld internal crystallization of brittle microstructure (martensite), so after welding or welding process welding using self heat, reasonable arrangement of weld, welding seam and heat affected zone heat treatment. The welding heat treatment is often used to preheat before welding, after welding withasbestos cloth covering slow cooling annealing, reach the purpose, its main function is to reduce the internal stress, improve the weld microstructure of martensite formation, reduce brittle tendency, preventing welding cracks.

Q: What is the difference between forging parts and casting parts?: Forging is in hot state through the metal hammer or press equipment produced by forging parts. A casting is a metal that is liquid and is poured into a cavity of a specified shape and cooled and solidified. It is the forging metal soft pinch molding, and casting the metal into thin cooling solidification.Forged parts are costly and have long production cycles.

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: What are the casting parts processing engineering?: Among them, special casting has metal mould casting, pressure casting, low pressure casting, lost wax casting (also known as precision casting), shell casting, lost foam casting, centrifugal casting, continuous casting, V casting, and clay casting

Q: How much is the amount of electrophoretic paint per square meter used in the casting?: It was a very simple question, and it was complicated by what you said.

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: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness: Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.

Q: Can the casting part be phosphating with the phosphating solution of the pickling board?: Like stainless steel casting, duplex stainless steel casting is phosphating, ductile iron gray iron is not required

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.
