Currently used to cut materials whenever compared to diamond hard, diamond cutting disc for abrasive industry is in a high position in the match, although the price is cheap, and grinding cup wheel trust in the future of the diamond cutting should be performed better experience
Integration with the domestic market, especially after learning of foreign ancestors craft cutting discs, diamond cutting skills abroad will become more junior.
Future diamond cutting discs there is a very large market, because the rock-cut diamond cutting tool is most useful, therefore, superficial discussion of stone cutting mechanism and the wear mechanism of diamond cutting equipment, diamond cutting things about the diamond grinding wheel production and the correct use reasonable means must exist
Pros and cons of diamond cutting discs varieties often much worse for other cutting material, cutting discs differences with other states with poor qualities of the diamond cutting discs currently abroad or in the sanding belt discussion behind developed world standards
In the abrasives industry, diamond cutting discs with a control instrument is universal, its primary notice is diamond cutting discs were faithful reason, rough cutting equipment is very common, so check abrasive industry in the development of particularly wide wide development of space

diamond tool wear
Diamond tool wear mechanism is more complex, can be divided into macro-and micro-abrasion wear, the diamond cup grinding wheel former mainly mechanical wear, which is dominated by thermal chemical wear. Diamond grinding tool breakage common form for the former flank wear, flank wear and edge chipping. In single crystal diamond tool sharpening process, requires the wear to the grinding tool to meet the requirements, but if the wear generated may damage not have a good grinding before the polishing pads flank. The edge cracking (i.e. chipping) is on the edge of the local stress exceeds the capacity of the diamond grinding wheel diamond cutting tool occurs, generally the diamond crystal (111) cleavage plane of the micro-damage caused. In the ultra-precision machining, diamond tool edge radius of the cutting edge is relatively small, which itself is hard and brittle materials, and because of its anisotropy and (111) surfaces prone to cleavage, with the vibration of the tool blade and grinding wheel grit the mouth of the impact of the role, it is often accompanied produce chipping.
film diamond
Diamond film synthesis technology and applied research on a global scale has grown rapidly, forming a "diamond film hot." In ten years, the development of gas-phase synthesis method to twenty kinds, general hourly rate of deposition is only 1 ~ 2um, how to accelerate the deposition rate has been one study. Recent developments in the deposition rate to 100um / h or more, up to 930um / h. We call thick diamond. Diamond is a pure diamond thick, close to the hardness of natural diamond, and PCD, PCDN diamond powder is mixed with the binding agent is sintered, so by the binding agent of the concrete diamond blades hardness, the hardness as the former. China has successfully mastered this technique, the maximum sediment thickness reaches 2.3mm. Has now been commercialized into the international advanced level.
PCD diamond thick film is that no different from the binding agent, is a pure diamond, the diamond core drills higher its hardness, and natural diamond different, it has isotropic, low cost, so in many respects replaced PCD. Will be used for wire drawing dies uniform wear, so much better than the quality of the wire wire drawing natural diamond dies. If the deposition further improve the quality in ultra-precision machining is also the possibility of replacing natural diamond, the field of ultra-precision so popular attention.
In short, diamond and superhard materials as superior performance, application constantly expanding, from the developed to the cup grinding wheels metal processing optical glass processing, stone processing, ceramics processing, processing of brittle materials is difficult for traditional processing areas, for a variety of industrial development will play a huge role in promoting broad prospects.

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
drill coring range
At present all of our minimum core drill coring range are 12MM and above, with the largest on the magnetic drill
Drill diameter reached 160MM, if the concrete diamond blades aperture is small, then I recommend using ordinary twist drill instead. Relatively speaking Why core drill so small it can not do? First, the tile blade holes by drilling, twist drill has been able to deal with common good. In contrast, the twist is much lower than the cost of the hollow drill bit, drill steel so we did not do the smallest aperture so small. Then why do we do it rail bricks? In fact, in order to solve our twist open a large hole encountered much resistance and developed, so long as we understand this, we also know that, in fact, there is an important reason that the grinding cup wheel smaller the aperture, But we take the three core drill blade tip the higher requirements, so the production cost would be a corresponding increase, compared to the twist drill, this is definitely select twist drill more.

Classification and granite structure features a variety of
so the variety, there are a variety of classification. Sub-divided according to types of minerals contained in black granite, muscovite granite, hornblende granite, two-mica granite. Constructed according to the structure can be divided into fine-grained granite, medium-grained granite, coarse-grained granite, porphyritic granite, porphyritic granite, geode granite and gneissic granite. Press contain minerals can be divided into cassiterite granite, niobium ore granite, granite containing beryllium, lithium mica granite, tourmaline granite. Common length petrochemical, greisenized, electrical and petrochemical since metamorphism.
Granite compact structure, high compressive strength, low water absorption, surface hardness, good chemical stability, durability, fire resistance, but poor. Granite was fine, the diamond cup grinding wheel grain, coarse granular structure, or porphyritic structure, fine uniform particles, the gap is small (porosity of 0.3% to 0.7%), water absorption is not high (water absorption is generally 0.15 % ~ 0.46%), with good frost resistance. High hardness of granite, its Mohs hardness of about 6, a density of 2.63g/cm3 to 2.75g/cm3 in between, the compression strength of 100-300MPa, in which fine-grained granite up to 300MPa or more, flexural strength sanding belt Average at 10 ~ 30Mpa. Often granite batholith, rock plants, rock and other forms of output, and is subject to regional tectonic control, generally larger than the size distribution is relatively broad, so mining convenient, easy out aniseed, and its joint development with the law, help shape the rules mined stone. Shortage of granite into high, can carry a variety of machining, sheet metal can fight good. There weathered granite is not easy, I can do diamond tools manufacturer outdoor decorative stone. Granite texture uniform texture, color, although dominated by light colors, but also very rich in red, white, yellow, green, black, purple, brown, beige, blue, etc., and relatively little change in its color, suitable for large the area of use.

marble flooring stone maintenance methods
Solution one: Using the compound before test a small inconspicuous area, such as a corner, and that does not make the green concrete
blades dark stone surface covered with scratches. Clear minor scratches operation is relatively simple, there is a lot of polishing powder sold. However, when using the polishing powder, most still require polishing machine or with the use of single-brush machine.
Solution two:
Recommend the use of liquid medicines, preferably two copies of the enzyme cleaning agents which can penetrate the dry core bits underlying stone, and can filter the dirt and grime to the surface. Enzyme vegetable stains particularly effective. Such cleaning agent available from high quality reseller of stone cleaning products purchased.
If the effect of this method is still not clear, the proposed solution of the enzyme detergent and decontamination powder mixed until a viscous creams similar to peanut butter. The mixed creams apply to pollution site, cover with plastic film, sealed with adhesive tape around. Maintaining 24-72 hours reaction time, followed by drying with a bamboo board to scrape ointment. If necessary, repeat it again. Once the contamination is removed, it is recommended to protect the stone repellant permeability, again in the future to avoid contamination.
If there are stains on the marble surface scratches while, it needs to be polished. Abrasive powder choices need to determine the construction side, there may be brick soil, cinders, sand paper or emery. Process may be more complex, so it would be best treated by professionals to operate. To clear some 305X305X10mm specifications sheet, it may damage their heels deep into the stone house, it may be difficult or almost can not afford sanding scratches. This situation is best seek expert assistance.
Solution three:
About bathtub ledge around the edge of the marble polishing pads stone and stains, the problem should be out in these marble never been protection, or improper maintenance. Since the performance of mild detergent ineffective, we recommend using a neutral cleaning agent and as thick powder to reconcile into a mixture of mud, the medicine paste deposited into the stone surface, then rub with a nylon pad. Powder in which the role of similar an abrasive that helps remove surface stubborn stains. If using this method does not work, it is recommended to use alkaline cleaning agent and clay powder are mixed to form a strong cleaning agent solution, other operation processes described above.
Speaking scratches on the ground, it is recommended to professionals to the scene to inspect and re-polishing marble surfaces. Since re-polishing usually requires the use of liquid or powdered products, or diamond polishing pad, so consult a professional to operate best. Available from local stone manufacturer or dealer inquiries, please recommend it more well-known stone care products, and for professional handling.
Often occur in the course of tiles loose, fall off and so on, because the current tile adhesives used in cement mortar bond fastness is not enough, and the long-term in a damp environment, so easy to loose and fall off. There is a method using a resin type adhesive paste tiles, not only to meet or exceed the strength of the tile body strength, and long in a humid environment will not cause loss.
Bathroom tiles are often greasy, water, rust, soap scum and other defile, to keep the porcelain surface cleaning without damaging the enamel surface shiny, you can use multi-Scouring pastes and clean. As for the tile gaps, first with a brush dipped in a little cream decontamination remove dirt, and then in the crevice brush a waterproofing agent can, so that not only impervious to water and can prevent mold growth. It is worth mentioning that a large number of families currently used for cleaning disinfectants contain a great influence on the pH of natural stone and other chemical substances, the color of the stone surface and internal mineral composition adverse reactions. Particularly serious, most of the cleaning agent must be in the stone surface reactions have the effect of at least five minutes, but during that time cleaning agent has been destroyed stone, so the stone surface should be cleaned bathrooms neutral pH value cleaning agent.
Alkaline cleaners can remove grease stains all kinds of animal and mechanical oil, and remove the ground layer of wax. Enhanced oil such as special cleaning agents; powerful wax from the water. PH detergent if used improperly, can cause cleaners in addition to waste, are also varying degrees of damage to the cleaning surface, and may even cause damage to the user's skin or eyes. Therefore we use acid detergents should note the following:
To understand their uses and contraindications should read the instructions carefully before use, or consult the supplier to obtain detailed user guide.
Before you use it in an inconspicuous place to do sample test to confirm cleaning materials will not cause harm to the premise of the dilution ratio used in accordance with the true work of cleaning solvents to dilute wearing work gloves, if necessary, wear goggles.
Avoid contact with skin or eyes stay cleaner cleaners cleaning the surface in time can not be too long after use with water over the net.
Can not be used on acid-sensitive surfaces, such as some detergents for marble, glass, metal and other surface damage effects

Therefore, China should realize the diamond tool industry from large to strong changes, you must also carry out all the work of independent innovation.
In recent years, some enterprises in independent innovation capacity-building to do some work in the technological development has also made some breakthroughs, but, objectively, in terms of research investment also studied the depth, product level, personnel structure, all there is a large shortage. Currently, companies are further increase investment in scientific research and technology, has "Enterprise Technology Center Project" included in the listing and financing projects to improve technology center hardware facilities, the construction set diamond tools, metal tools, power tools into one comprehensive state-level enterprise technical center.
3. Strengthen basic research, accelerate the tct saw blades process of industrialization of scientific research, and constantly develop new products, applications
In recent years, with the occasion of the new materials, new technologies, new processes, new equipment innovations continue to emerge, such as superfine pre-alloy powder, laser processing, vacuum brazing technology, diamond plating technology, diamond uniform technology and other cutting-edge new technology , being highly concerned with the key R & D, R & D results also gradually industrialized. As these research achievements in industry, diamond tool performance on continuous improvement, functionality continues to expand, currently has gradually extended its scope of application to the semiconductor, aerospace, information and many other fields, for diamond tools manufacturing enterprises to provide high profits and huge development space.
diamond cutting discs primary process
The first diamond cutting discs work! Diamond cutting discs at the moment the use of steel and sds drill bits other industries are relatively trivial.
So the primary vocals diamond cutting disc is welded diamond cutting discs: sub-frequency welding and 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 concrete ring saw Marginal touch with the matrix resulting metallurgical melting beans cut. Sintered diamond cutting discs: min cold sintering and hot pressing are two constraints sintering.
Diamond cutting discs: the 9 inch saw blade powder through the process of electroplating way head attached to the substrate.

discusses the diamond wheel diamond place
Transition index equal to the diamond layer adjacent to the substrate secure in the sector. Our base for masonry saw blades convergence abrasive layer and in the use of time by flange firmly clamped grinding spindle.
Suri environment outside as more rounded shape. There is not a diamond wheel diamond produced from. It may be divided into three layers, namely task layer, the substrate, the tuck point blades transition layer. As long as the task layer is called the diamond layer, the abrasive agent and filler compact form determines its seems like diamond to do tough weakness. Transition layer and the substrate are non-diamond layer.
Even as a diamond grinding wheel sand root arrived with its most empty thinking is to see consistent use of concrete core bits materials abrasive. Its primary organs are made of metal powder, resin powder, ceramic and metal plating as liaison agent.
How the diamond wheel on three disjointed comprehensive alone. Like a corporate team, this three Qianan choice with a good grade diamond wheel diamond place.
