What impact concrete diamond blades cutting performance

We all know that the production is a special diamond saw, this blade is mainly used to cut about relatively hard material, but this blade can cut those specific substances it? Maybe we do not understand, specifically for you Introduction. Pick a good blade tips you know? Watching and small series. 1, you can see the saw blade diamond particles, if it is bad Saw blades are generally of poor quality, so it is very hard to use, or simply cut does not move. What impact blade cutting performance, you know? When conducting cutting blade, if exposed, would have an impact on the protruding cut, how  GUSHI diamond polishing tools to avoid this phenomenon?
When the particle size can be used during the cutting blade larger extent outcropping material will have a faster rate cut teams. Coarse particles are generally used to cut soft materials, and the smaller particle size was used for cutting hard materials. When making the cut, usually with increasing particle number, the number of particles per carat increases. So choosing the right number is a key tool to ensure performance.
2, the time of purchase, pay attention to the  GUSHI sds hammer drill bits texture of cutting, cutting should be very smooth, if there is a halt under the circumstances is a bad blade. 3, you can see through the head color is good or bad, the normal is a silvery white, if hair dark, indicating the knife is more and more impurities. You can use the diamond saw for aluminum, copper, magnesium and its alloys, tungsten carbide, wear resistance materials, wood, metal matrix composites can be cut. Directly affects the hardness of the blade to the cutting speed, and depth of progress. What is a diamond blade? If you are not a professional staff, we do not know, because we often say  GUSHI abrasive grinding wheels we choose a diamond with the now not the same as in the past, we do not know what is the diamond, but today found in all walks of life, Even in many areas, we will often encounter the shadow of the diamond, in which this special day, we sincerely wish you friends, happy New Year, life is happy happy!

Some simple narrative and the role of wood saw blades

Classified by material , the current domestic production of diamond saw

blade material matrix mainly 50Mn2V, 75Crl and 65Mn three materials , as

well as some low-end market with a 45 # steel. 45 # steel is ordinary

carbon steel , 65Mn spring steel is common , 75Crl high carbon alloy steel

. In comparison , 50Mn2V is a carbon steel , 50Mn2V fine grain size , high

thermal stability, high strength and toughness , fatigue resistance and

heat resistance. 50Mn2V saw the matrix material , with a number of complex

welding , long service life , the welding head blade easily deformed, easy

to repair after deformation , etc., as well as in the course of the

product so that the effect of high rigidity gradually , so 50Mn2V

materials are widely used in the processing and production of diamond saw

blade matrix . Classification according to specifications , the domestic

stone processing blade matrix size starting from ф200mm maximum of

ф3500mm ( foreign specifications for maximum saw blade towel 5000mm).

Which , dp200-600ram specifications mainly for trimming ( cutting edge )

processing semi-finished sheet ; ф650 above specifications is mainly used

for similar tombstone , grave stone columns and other thick (column )

forming sawing and for sawing blocks of cut ( board ) material processing.

Especially ф1600mm currently the most widely used blade matrix ф200 ~

600mm Specifications saw the matrix , due to the low technical content,

the technical and quality requirements are not high, only requires the

ability to use cutting edge on the line , the market tends to be

homogeneous product technology . Currently ф200 ~ 600mm blade matrix

specification hundreds of manufacturers , the market competition is mainly

price competition as the main means fierce competition in the industry ,

profit margins are low , some domestic enterprises do not intend to have

the strength to compete in this low-end market . Along with the increasing

emphasis on environmental protection , mining blocks scarcity of

resources, power resources in tight supply , rising  GUSHI diamond polishing tools stone enterprise

manufacturing costs, increased competition , a number of energy-saving ,

resource-based , environmentally friendly saw the matrix more and more

markets welcome , customer demand for varieties blade matrix there are

some new features: 1. Sheet , thin blade -based thin sheet , thin blade

substrate sheet , the thickness of the substrate primarily to distinguish

the ф1600mm substrate normal thickness 7.3mm, 6.5mm or  less in thickness

of the sheet is called substrate thickness 5.5 mm or less called ultrathin

sheet substrate . The use of thin , thin film substrate cutting blade

granite and marble slabs , can significantly improve efficiency and cut

blocks the yield , reduce power consumption , such as the GUSHI core bits for concrete  use of ultra-

thin thickness of 4.0mm. Ф1600mm matrix can improve cutting efficiency

over 10% , more than 20% reduction in power consumption , increase

utilization of 16% or more blocks . As the thin , ultra-thin diamond blade

matrix thin film thickness , diameter, large deformation during heat

treatment , and thus the degree of heat treatment on the plane and HRC

control is very important. And because the GUSHI concrete diamond blades  thickness of the thin end jump

to adjust the stress , comprising detecting great difficulties are caused

, in general , only by manual correction is difficult to achieve a good

level and detecting the effect .

blades matrix organization and properties of concrete diamond

Firstly, studied the sintering process and composition ratios on the mechanical properties of the matrix-free diamond. Using SEM, EDS for free diamond matrix organization observed and analyzed, revealing the variation matrix microstructure and mechanical performance. ANOVA using orthogonal experimental sintering process and carcass composition ratio is optimized. Then the carcass by adding different types of diamond, the effect of the mechanical properties of diamond on the carcass. Using SEM, EDS and the binding mode of binding conditions between diamond and matrix were observed and analyzed. Finally, Fujian 603 granite sawing objects, conduct real cut, copper-based detection of  GUSHI concrete saws different types of diamond saw blades wear prepared. Draw the following conclusions:
770 ℃ mechanical properties of the sintered matrix is ​​significantly higher than 690 ℃ of the carcass, carcass mechanical properties of thermal insulation 9min higher than 3min carcass. Matrix hardness is higher than with 8% WC carcass containing 4% WC, but the flexural strength and carcass containing 4% WC is roughly equal. Mechanical properties of the matrix containing 18% Ni is higher than 8% Ni containing carcass.
Flocculent white carcass organized by Cu, Sn, Fe, Ni for the four elements of the reinforcing phase is formed, the content of the tissue, the higher the mechanical properties of the carcass. With the improvement of the mechanical properties of the carcass, carcass fracture mode changes from brittle GUSHI concrete ring saw  fracture to the fracture toughness. Content of 8% WC, WC agglomeration occurs in a localized area. Analysis of variance optimization results show that: the best sintering process and carcass composition ratio of.
 After adding uncoated diamond, a sharp decline in the mechanical properties of the matrix. After adding titanium diamond matrix mechanical properties compared with uncoated diamond matrix adding a substantial increase. While adding titanium diamond and nanodiamond carcass compared with only adding GUSHI colde saw blade  titanium diamond matrix, the mechanical properties decreased slightly. Uncoated diamond exists at the interface with the carcass obvious gap for mechanical bond between the diamond and the carcass. Between diamond and titanium matrix tightly, no significant gap at the interface, EDS analysis showed that the chemical bonding between diamond and titanium matrix. Nanodiamond combination of adsorption in the form of the carcass, carcass nanodiamond adsorbed on the particle surface.

wood saw blades of some of the major categories

Saw classification
In today's industrial production, life, saw the use of one of the most common, the most widely used, the product range of the  GUSHI turbo diamond blade most complex tool.
Because of this, we need to classify from a different perspective:
One, depending on the material classification
HSS film (HSS saw blade), solid carbide saw blades, hacksaw tungsten film, alloy tipped saw blades, diamond saw blades, etc.
Second, depending on the application classification
Cutter blades, machine saw, hand saw, metal GUSHI stone polishing pads  special blade (aluminum blade, blade cut copper, stainless steel blades, etc.), pipe cutting circular saw blades, wood with a saw blade, stone blade, Qieya Ke Li saw blades
Third, the tooth can be classified according to
Toothless saw blades, triangular tooth saw blade, circular saw blade teeth, staggered tooth saw blade, the level of tooth saw blade, coarse tooth saw blade, tooth saw blade, fine-tooth saw blade, tipped saw blades
Fourth, the coating classification
White hacksaw piece (character), nitride blade (black), titanium blade (gold), chromium nitride (color), etc.
Five other classification and GUSHI concrete polishing pads  call
Cutting blade, cutting blade, cutting blade, cut saw, the overall blade, tipped saw blade, thin blade, etc.

On the next to improve the quality of high-quality concrete diamond blades technical solutions

Aligned with the status quo, the end of Britain repeatedly theory, a set of production efficiency, quality diamond saw blade skills programs available.
1, the choice of the production function stable, coarse particles, heat stable and good (ti and tfi straight near to) the high-strength diamond. What is essentially a diamond diamond carcass must process conditions under fixed on the operating base, mainly by diamond grinding agent, not the same as cutting role to process the stone. Thus, the original data (diamond) quality, particle size and concentration on the diamond thing has a decisive role.
 2, although charcoal powder into a strong element of progress diamond control force. In the processing of diamond saw blades, diamond blade carcass if there is a good operating force, diamond blade is a distinguished, not prematurely fall, when cut sharp, high power. Usually top end of the outer plating layer of diamond strong carbon compound, the constituent metal elements, such as plating, titanium, chromium, nickel, tungsten, etc., in order to progress with the matrix powder of diamond bonded and sintered at high temperature to avoid favor diamond After oxidation and graphitization; other top end of the carcass can also be powder, carbon powder of a few strong increase of elements, such as: molybdenum, chromium, tungsten powder. Because this type of powder gold, moisture resistance and better affinity diamond, diamond sintering metal carcass appearance constitute carbide alloys, diamond and matrix metal in favor of chemical bonding and Metallurgy contact, and greatly improved the carcass diamond manipulation force.
  3, to improve the diamond particle size ratio. Traditional ratio, the sharp tip to more, spend more coarse diamond, and vice versa with a fine diamond. Of course yes, but it has been less than optimal operating power. Because the hardness and elastic modulus of diamond art high temperature GUSHI abrasive grinding wheels  sintering is difficult when the onset of plastic deformation. Selected ratio, before sintering progress bulk density of the diamond particles on the progress of the tool wear ratio is advantageous. Britain at the end repeated test results usually head coarse, coarse, fine diamond particles composed of three kinds, the optimal granularity share 1:0.0227:0.071. 4, the choice of ultra-fine powder and pre-alloyed powders. Ultrafine powder sintering temperature dropped in favor of progressive matrix hardness. The pre-alloy powder, the top end of the three-dimensional mixing, greatly reducing the touching moments powder and air, to avoid premature loss of the low melting point metal segregation and contribute to the progress of the strength of sintered products, increase the operating force of the diamond.
 5, increasing the excess of rare earth  GUSHI concrete ring saw elements (such as lanthanum, cerium, etc.) in a matrix powder. Contact agent can significantly decrease the wear features progressive diamond saw blade to cut the power.
  6, a selection of cold thermal sintering process, maintain vacuum sintering atmosphere. Top end of the cold tip after sintering is reflected in a very sharp cutting process, many progressive power production while maintaining a vacuum sintering atmosphere to avoid oxidation of the powder, activated sintering, both the head progress function and prolong the graphite mold The number of longevity, but also to decrease production costs.
  7, the correct welding technology, nowadays Diamond Park saw both use high-frequency welding machines to weld, the  GUSHI colde saw blade welding head is easy to show the second "burn" and head off appearance. Not only unsafe, and the impact of production, and therefore should be used in high-strength, permeability good silver solder pieces for welding production.

HSS blade radiator how chamfered concrete blades

Saw blade plate quality is very important. Because the blade to adjust the rotation, it has to pass the cutting force while keeping the stability of the work . Not only has excellent static blade geometry  GUSHI carbide saw blades and accuracy , and more importantly, its dynamic characteristics. When the cutting blade continuously , the heat generated sawtooth cutting saws will be transmitted to the temperature rise of saws , saws quality in this case also to maintain the accuracy of position , and the poor quality of the blade saw board warpage occurs , the impact of cutting accuracy. Dynamic stability is particularly important for sawing boards of several pieces into a fine blade set  GUSHI colde saw blade conditions for use . When multiple devices using a set piece saw blade instability , how can guarantee the quality of the longitudinal opening material . Saw blade plate and the head is an integral part of quality . Depending on the angle of the blade to grind the teeth , with left , center and right . There are left, right , middle . Tooth tooth width ( tooth density ) with the cut material size , wall thickness of the blade a great relationship, the more books tooth wall thickness is relatively dense , thick wall thickness should open GUSHI stone polishing pads  wide more, do not understand what you can always ask me, usually online.
        To be determined according to the thickness of the blade cutting the material , size open tooth , first , on the edge of the blade off the mouth of the well , and the second , on the grinding wheel grinding is good , and the third , chamfer should be uniform.

Some applications use glass blades

 It should be noted that the pre-alloy powder has been laser welded diamond saw with wood powder material of the buffer layer growth of the target object of [17,23], because: the pre-atomized powder alloy powder manufacturing process used to ensure Average ingredients conducive compressive and flexural strength improved sintering products; may reduce the brick saws  sintering temperature and shorter sintering time, especially the fate of more obvious when using ultrafine or nano pre-alloy powder; favor of pre-alloyed elements diversification and reduce the amount of cobalt. Built with reinforced concrete for large-building, with a diamond wire saw cutting orderly enumeration is very convenient, and did not happen very big noise and dust.
  2 welding process laser welding diamond saw blade woodworking are differences thick welding dissimilar materials, the impact of the tile cutter  identity of many of its welding quality, collecting the preparation before welding, laser beam quality, laser power, welding speed, focal position of the laser beam offset , the angle of incidence of the laser beam, care of the gas flow, and now in this regard should be said that the fighting strength mature.
 But the transition layer can not contain low melting point metals such as tin and other elements, these elements easily because of evaporation and vaporization stomata occur, but can intervene from a small amount of solid solution strengthening, adding to abrasion and cut and weld concrete polishing pads  porosity dip  r mn elements. Thus, in the process of these spaces can easily be metal shavings clogging the worst is leading to "burn" the work and become waste. , In the beginning of cutting and curb cutting, do not feed too fast to avoid broken teeth and damaged.

Some simple requirements of concrete diamond blades

The impact of different ways of diamond production dominate the range and performance of the blade. Diamond saw blade production methods related to its hegemony, at present, the production of diamond saw dying dying making way to stop the use of sintering methods, there are few ways plated blade production, there is a common way to stop cold sintering sintering, hot pressing and sintering sintering welding three kinds  GUSHI brick saws dying approach.
Diamond saw domestic market is the largest market in the world, but in the level of the blade, variety, scope and construction skills to dominate other aspects and there are still a large gap, therefore, whether it is on the market have the skills or its development. So, with the further development of technology, diamond saw blades will dominate the succession development, market growth will inherit. Dominate the range of diamond saw blade is very strewn in the construction of stone, glass, ceramics, crystals, gemstones, iron and other materials processing and houses, avenues, bridges, etc. in both utilization. Meanwhile, along with the diamond saw blade production GUSHI core bits for concrete  skills constantly updated and mature, are constantly expanding the range to dominate in many countries have throughout fortune grip. Diamond saw blade is widely used in stone cutting aspects, something major cutting hard points, so choose only one sharp and durable diamond saw blade is very important. Types of diamond saw blades are more sharp and durability is not the same, to choose a good diamond saw blades, diamond saw blades which we need to have a detailed understanding of, or else it is easy to be fooled insiders will in the past. And each person's identification methods are not the same, which we need to understand all aspects of the appearance of the head alone can not see, a lot of things that are hypocritical. High diamond saw blade is sharp knives door requires a diamond knife fast, usually are some hard cutting some things, so diamond saw blade life will be short, easily damaged. If you want to judge from the appearance of a sharp diamond blade is GUSHI dry core drill bits  high, is a more complicated issue, and the need to explore slowly. Some people are not very professional in the manufacture of diamond saw blades, when due to the technology is not very professional, it will directly affect the diamond saw blades sharp and highly durable. One method is generally the easiest to check whether the process is cutting the wrong time to listen to the voices of hybrid and low, high, and if a single voice, the quality of diamond saw blade is better.
