The primary work of GUSHI Diamond toolsthe diamond cutting discs

Diamond cutting discs primary work ! Diamond cutting discs used in the steel industry at the moment are trivial compared So the primary vocal pieces are welded diamond cutting diamond concrete diamond bladescutting discs : two of the high-frequency welding and laser welding , high frequency welding pass is too high temperature solidification media will head welded together with the matrix , laser welding, laser beam through the head too concrete saw bladeslow marginal touch with the matrix resulting metallurgical melting beans cut . Sintered diamond cutting discs : two sintering and sintering of cold pressing, sintering constraints .Electroplated diamond cutting discs : the head through the process of plating powder adheres to the substrate.

Diamond tool materials species classification

Synthetic polycrystalline diamond (PCD) and synthetic polycrystalline diamond and carbide composite blade (PCD / CC)
PCD is at high temperature ( about 1800 ℃), pressure (5 ~ 6MPa) , the use of cobalt and other metal binding agent to a  oncrete crack chaser number of polycrystalline diamond crystal powder polycrystalline material , although slightly lower than the hardness of a single crystal diamond , but it is randomly oriented diamond grains polymerization , is isotropic , as can be arbitrarily oriented cutting tool sharpening , no natural diamond that must be selected as the best cleavage plane as a rake . In cutting, the cutting edge is very sensitive for accidental damage , wear resistance is also strong , long stay sharp cutting edge , can be used when machining high cutting speed and larger cutting depth ( to eat deep ) , life concrete core bits  is generally higher than the WC-based cemented carbide cutting tools 10 to 500 times , and because the metal binding agent PCD has conductivity , making PCD easy to cut to shape , and is a rich source of raw materials , the price is only a few tenth of natural diamond a fraction of the ten have become traditions WC-based cemented carbide cutting tools , high-performance alternatives.
PCD inserts to improve the toughness and weldability in the cemented carbide substrate , sintered or pressed on the surface of 0.5 ~ 1mm thick layer of the composition of PCD diamond composite blade (PCD / CC). PCD / CC welding or machine folder available way of making knives. Due to its good weldability , regrinding easy , low cost, and polishing pads for granite  therefore widely used. Hereupon , PCD and PCD / CC sharp cutting edge of the tool and are not as good surface quality single crystal diamond , while its workability is poor, the grinding ratio is small , it is difficult according to the geometry of any shape head , still not easy to manufacture with chipbreakers indexable end mills and other geometric shapes and complex products.
CVD diamond
CVD diamond is a diamond material of high wear resistance of pure , non- binding agent , which is at low pressure (<0.1MPa) prepared under . CVD diamond films are coated CVD (CD) and CVD thick (TFD) forms.
CD is a CVD ( chemical vapor deposition ) process , the carbide substrate ( K type alloy used ) is deposited to a thickness of about 10 ~ 30μm, composed of a polycrystalline diamond film is made .

diamond abrasive and filler mixed in advance

Diamond grinding wheel used more widely , mainly for grinding or cutting , then you know how to process diamond wheel is made ​​of it ? Here we introduce a simple method for processing diamond wheel :
Prior and diamond abrasive fillers , these fillers can be salts, glass beads or magnetic particles. After sds plus drill bits  bonding , 20% the thickness of the filler particles are bonded by a metal binding agent , these fillers were used in addition to the following methods : dissolution method , sublimation method or magnetic method . This method of diamond abrasive filler particle size and particle size roughly the same amount of filler to make the diamond abrasive work surface to achieve the required concentration . The disadvantage of these methods is complicated in addition to the wet saw blades  filler , require special set of methods .
In addition to the filler is a relatively simple method using the spherical filler particles, the surface is smooth, a metal binding agent is first deposited diamond abrasive grains having a thickness of 20% of the height , and the filler brush with a brush , and finally continue the metal binding agent is deposited to predetermined thickness , use of this method to different metal bonded surface roughness and shape of the particles of different capacities of the gripping effect, the drawback is that  concrete cutting blade the diamond abrasive particle size of the filler particle size rather , after bonding and thus in the same plane, with the mechanical in addition to the packing method , there may give some diamond abrasive brush together , especially those close to equal area like shape of the particles , smooth surface of the particles .

on dry cutting diamond tool Precautions

The current tool materials, such as new carbide, ceramic, CBN and PCBN and other high-temperature wear performance sufficient, able to dry cutting conditions.
  Dry cutting tool materials must have excellent hot hardness and wear resistance as to be effective to withstand  dry pads high temperatures during the cutting process; low friction coefficient, in order to reduce the tool and the chip and suppressing the friction between the surface temperature of the cutting rise. To implement the requirements of the tool dry cutting, it is necessary for the tool coating, is an important way to improve tool performance. In a robust surface coating of the tool base body and  hole saw blades wear resistant materials are very high, so that the cutting tool and the chip in the process of increase of a thermal barrier between, to prevent heat transfer to the tool base body decreases Tool wear and heat generation. The tool geometry, the dry cutting tool design should strive to follow the "low cutting temperature" design principles, the tool must be designed so  flap wheels that the processing structure of the heat generated in the process as little as possible, that the tool structure should strive to achieve low cutting forces and low friction.

cutter mold industry consumption characteristics

Diamond tool manufacturers say that in order to achieve mold lean manufacturing, mold enterprise scientific organization tool procurement and inventory management, need to study and  metal drill bits explore how to ensure that the production line functioning circumstances reduce tool inventory of funds used to optimize the tool's minimum inventory settings, the tool the starting point of purchase, purchase frequency and reasonable tool procurement quantities, to establish an effective early warning system tool, emergency response mechanisms and rapid response mechanism, there is a scientific and effective way tracking, status monitoring tool inventory and  carbide saw blades procurement status. It is understood that 68.5% of the total cost of the user enterprise cost of tools for less than 3%, and developed the tool manufacturing costs accounted for about 4% of the production costs, constitute a big gap, which is caused by the low level of China's manufacturing cutting a factor.
China mold industry is fragmented, low-scale, low-level phenomena, China mold manufacturer is only a handful of a few particularly large scale, and the remaining are mostly small and medium scale. These conditions determine the mold industry users of the tool features: procurement volume increased, and the number of frequent purchases, ie up to two months or so purchasing one, this reflects the consumer market is relatively mature, the mold industry in developing the budget tool users more inclined on flexibility, rather than retaining excess inventory. Meanwhile, the ring saw blades  user purchases the flexibility for those who have not yet entered the tool provider, the market provides ready access to opportunities. As demand procurement, have been replaced with another brand competition is also increasing.

Granite Building Materials may be carcinogenic

 carcinogenic killer careful radiationPeople benzene, formaldehyde and other indoor pollution has gradually attention, but also lack of knowledge building radiation contamination. She  drill bits pointed out that the mostMuch hidden from the stone. Due to the earth's crust contain radioactive substances, natural stone, too.
Radioactive stone on the human body, there are two, one is the stone decay of radionuclides emit X-rays of the human bodyCause external irradiation, but the probability is very low; Another is the release of radon exposure on the human body inside. Radon is toShell radioactive uranium, radium and thorium decay products of radon is listed as one of 19 kinds of carcinogenic substances, mainly the production of induced lung cancerAccording to testing, the radioactivity of different colors are different stone. Highest red and green, white, black is the mostLow. Therefore, consumers should choose carefully the red, green, or red blotches with granite varieties. He said that the wet granite pads  graniticExtensive use of stone should not be in the room, especially not in the bedroom, children's room to use.
Using more than 60% the proportion of Guangdong
"The use of granite is indeed very popular in Guangdong." Guangdong Provincial Bureau of Nonferrous Metal Geological Exploration team captain Zhang Xinxiong 931Said Granite is an important building material in Guangdong, and some of the more serious areas of granite radiation. Geological SurveyAlthough the department has long been investigated, but now this problem has not yet attracted people's attention.
It is understood that the  cutting blades level of radioactivity is divided into stone by A, B, C three categories, according to regulations, only the A class can be used in home roomInterior decoration. House renovated to do the best detection
Natural marble, they need to be taken to dilute the pollution ways to reduce pollution. Radon half-life of only 3.2 days at roomRadon concentration in the open doors and windows after 20 to 30 minutes afterthe outdoor levels can be reduced.
Therefore, the easiest way is to enhance ventilation. Just a furnished room is best to be detected. If the test resultsIf failed, you can use lower radiation shield paint or lead-free installation, to prevent the release of radon from building materials. If the radioactive targetToo high, the stone must be replaced immediately.

granite and marble differences

 Granite is igneous intrusion by the underground magma cooled and crystallized, and granitic rocks like. Crystal structure and with visible texture. It consists of feldspar (usually potash feldspar and oligoclase) and green concrete blades  quartz, mixed with a small amount of mica (biotite or muscovite) and trace minerals, such as: zircon, apatite, magnetite, ilmenite and sphene and so on. Granite main ingredient is silica, the  concrete core bits content of about 65% - 85%. The chemical properties of granite is weakly acidic.Under normal circumstances, whitish or gray granite, because mixed with dark crystal, with the appearance of spots, feldspar join makes it red or flesh-colored. Granite is formed by the crystallization of magma cooled slowly, deep below the surface, when the cooling rate is unusually slow when it forms a very rough texture of granite, known as pegmatite. Granite and other crystalline rocks form the basis of continental plates, it is also exposed to the surface of the earth is the most common intrusive rocks.Although granite is considered by melting the material or the formation of igneous magma, but there is plenty of evidence that some form of granite rock is locally deformed or previous product, they do not go through the process of a liquid or melted to rearrange and recrystallization.The proportion of granite between 2.63 to 2.75, the compressive strength of 1,050 ~ 14,000 kg / sq cm (15,000 to 20,000 pounds / square inch). Because the  sanding paper intensity ratio of sandstone granite, limestone and marble, it is more difficult to exploit. Since the formation of the special conditions of granite and structural characteristics of the firm

diamond saw blades in the watch of

Small diameter diamond saw blade for cutting marble, granite, concrete,

refractory materials, ceramics and other brittle temper material. Cutting

equipment is usually portable cutting machine, grinder, individuals have the

product efficiency to the  diamond blades desktop machine, such as tiles blades. Basis for the

production of small diameter diamond saw blade grounding strange Suri into

green sheets and welding pieces.
    Sintered slices of raw produce high performance, value related to the high

prices, but in the use of easily thrown head separatist course, litter, saw the

matrix beans sectional, saw blade is not sharp and so on.
     Sintered saw blade roughly divided into: sub tooth saw blade, blade-shaped

surrounding succession, the  wet core bits turbine blade region have state type blade, turbo

status of tooth blade. The same day as the chip welding laser welding are low

the product. Laser welded saw the price expensive, expensive laser welding

facility the cause is, the matrix I expensive, but also the necessary head cold

after sintering, sintered saw blade raw produce absolute performance pay is

low, but the  wood saw blades laser welding of the blade tip and matrix strength is higher, with

the use of long life, less prone to broken busted, insurance performance

advantages.

diamond cutting primary process

The first diamond cutting discs work! Diamond cutting discs at the moment the use of steel and concrete core bits  other industries are relatively trivial.
       So the primary vocals diamond cutting disc is welded diamond cutting discs: sub-frequency welding and marble polishing pads  laser welding are two, high-frequency welding pass is too high coagulation medium tip and the substrate will be welded, laser welding laser beam through the head too low Marginal touch with the matrix resulting metallurgical melting beans cut. Sintered diamond cutting discs: min cold sintering and cup grinding wheels  hot pressing are two constraints sintering.
    Diamond cutting discs: the powder through the process of electroplating way head attached to the substrate.

concrete Driving Precautions

Concrete mixer commonly used in the concrete core bits  construction field, is used to transport concrete building dedicated truck. Because of its shape like a snail, it is often called cement trucks. Such vehicles are equipped with a rear cylindrical mixing drum for loading mixed concrete. The mixing drum even when driving on the road the diamond polishing pads  driver is also kept turning, the only way to prevent the carrying cement solidification. Then, pulling dozens of tons of "moving" of the goods, operation and general goods What are the different? Driving this car and what precautions do? Concrete mixer one can narrow the 30 tons of cargo took such a heavy things uphill, downhill, turn. slightly handled properly it may cause a rollover in this regard LIU Ji-red deep emotion. "Because we fight back in the car kept turning, turning, if turning direction and bucket rotating in the grinding stone  same direction it would have to be particularly careful .. We know the centrifugal force generated when the car turns
