Characteristics of the diamond wheel to decide what

Diamond Wheel is a highly professional product, very few non-professionals for its understanding. Characteristics of the diamond wheel to decide what the majority of users are concerned , but also troubled by a user of important issues. Professionals that features a good diamond wheel is determined by the following factors:
By the characteristics of the abrasive wheel , grain size, hardness , binders , shape and other factors to determine abrasive grinding wheels  the size of the abrasive particle size selection , primarily related to the surface roughness and productivity . When roughing , grinding margin, requires a larger surface roughness values ​​should be used in coarse grains . Because coarse grains , large pores , grinding depth can be larger wheel clogging and fever. When grinding , margin is small, requiring a lower roughness values ​​, you can select finer grit . Generally speaking , the more fine abrasive grinding surface roughness as possible.
Concentration of diamond grinding wheel selection we understand the concentration of diamond grinding it? Refers  masonry drill bits to the concentration of the abrasive layer of the abrasive content . Today we have to say is how the concentration of diamond wheels were chosen , I hope you will like the following content.
① diamond grinding wheel generally 50 % -100 % concentration ; most 75% , the time required to finish higher than 75 %, forming the grinding wheel and requires a long life , can be 100% or more ;
② diamond products in general use 25% -150 % concentration ; cutting blade which coarse-grained , concentrations are concrete saws  generally higher than at the end , that is 25-50 % higher fine-grained ; while other metal bonded grinding wheel generally requires concentration to 50 % to 100 % concentration . Overall, with a higher concentration of coarse , semi- fine grinding with a moderate concentration , and grinding and polishing with a higher concentration .

Diamond Wheel introduce a variety of classification

Diamond grinding wheel by binding agents can be divided into: resin bond diamond wheel ; vitrified diamond grinding wheel ; metal bond diamond wheel ( bronze bond diamond wheel ) diamond grinding wheel according  industrial saw blades to the production process can be divided into: sintered diamond wheel ( resin bond diamond grinding wheel ; vitrified diamond grinding wheel ; metal bond diamond wheel ) ; electroplated diamond grinding wheel ; brazed diamond wheel . Diamond grinding wheel can be divided according to : diamond with diamond grinding wheel ; grinding carbide with diamond wheel ( diamond cutter grinding wheel ) ; PDC with diamond grinding wheel ; coreless grinder with a diamond centerless grinding wheel ; grinding ceramics with wood drill bits  a diamond wheel ; cutting diamond wheel ( also known as diamond cutting discs ) ; diamond saw .
Diamond grinding wheel by the appearance or shape can be divided into : Parallel grinding wheel ; cylindrical grinding wheel ; cup wheels ; Wheel Bowl ; disc wheel ; grinding wheel ; disc and so on.
First we have to consider its abrasive texture, iron roller, rubber roller , copper roller and so on. Do not have to be the same as the material pairing with the corresponding wheel .
Second, we have to consider is  wet tile saw the size of choice, when you want to select coarse grained diamond wheels and vice versa , when faced with ultra- fine grinding wheel to use powder .
Finally also take into account the hardness , wheel wear fast, then you want to do the following:
One , trying to improve its wheel speed
2 , the pressure roller will have to reduce the speed aspect
3, to improve longitudinal feed speed

Diamond saw blades for cutting metal can cause

1 , diamond saw blade is characterized by soft afraid of hard afraid
2, the metal part of the plastic material , is for marble, glass , the metal to be "soft" is much more
3 , marble, glass is brittle concrete saw blades  material , harder than the metal
4 , diamond is a valuable material , although the diamond saw blade diamond is a man , but it is expensive , it is made ​​by a method using powder metallurgy , that is, the diamond particles in the metal powder mixed sintering rather backward over the blade , the blade is to wrap diamond grinding wheel for metal rubbed off , exposing the diamond particles less than half the pieces , this is the diamond particles exposed head was cut marble "blade"
5 , diamond saw blade "cut" marble , it granite blade   is actually a diamond will powdered marble , marble which will "cut" open to the
6, if using a diamond saw blade to "cut" metal , "soft" diamond particles of the metal will be "glued down " so that the diamond blade failure . Remember: Do not use diamond saw to cut metal !
7 , with ordinary thin grinding wheel cutting metal is possible, although this wheel is a metal ground into powder, but not as good as diamond grit is precious , and that sand is bonded with a special adhesive overall shape , that is, said that the whole can be " cut" of the sand grains , cylindrical sanding off the back of the sand can continue to "cut"

diamond saw blade speed by equipment conditions

(1) diamond blade speed: in practical work, diamond saw blade speed by equipment conditions, saw the quality and the nature of the restrictions before sawing stone. From the optimum blade life and cutting efficiency, it should be selected depending on the nature of the stone saw blade speed. Sawing carbide drill bits  granite, the blade speed at 25m ~ 35m / s within the selected range. For high quartz content and difficult cutting granite, remove the blade speed limit is appropriate. In the production of granite tiles, the use of smaller diameter diamond saw blade, wire speed can reach 35m / s.
(2) Cutting Depth: diamond cutting depth is related to wear, effective cutting, saw cutting force conditions and the 12 inch saw blade  nature of the important parameters of stone. Generally speaking, when the line speed diamond saw blade is high, should be selected for cutting of small depth, from the current technology, the cutting depth of the diamond can choose between 1mm ~ 10mm. Usually with a large diameter saw blade cutting granite blocks, the cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time. When the line speed diamond saw blade is large, a large cutting depth should be selected. But in performance and tool strength saw the extent permitted, should try to take a greater depth of cut for cutting to improve cutting efficiency. When the machined surface colde saw blade  when requested, should be used small depth of cut. (3) diamond saw blade feed rate: Feed speed incurs sawing stone feed rate. Its size sawing rate impact, the force and the cutting blade heat dissipation area. Its value should be based on the nature of the selected cutting stone. Generally speaking, sawing softer stone, such as marble, may be appropriate to increase the feed speed, if the feed rate is too low, more conducive to high cutting rates. Sawing fine structure, relatively homogeneous granite, may be appropriate to increase the feed speed, feed rate is too low if the diamond blade easily be polished. But sawing UNEVEN coarse granite structure, should reduce feed speed, otherwise it will cause the blade vibration and reduce fragmentation leading diamond cutting rates. Granite cutting feed rate is generally 9m ~ 12m/min within the selected range.

Grinding wheel is the most important one class of abrasive.

 Grinding wheel is the most important one class of abrasive. Added to the abrasive wheel is binding agent, the green compacts, drying and calcining a porous body made. As abrasives, binders and  tuck point blades manufacturing process is different, the wheel characteristics vary greatly, so the grinding machining quality, productivity and economy have a significant impact. Mainly by the grinding wheel abrasive characteristics, the intensity, binders, hardness, structure, shape and size and other factors. Wheel variety.
Can be divided according to the  polishing pads for granite ordinary abrasives abrasives (corundum and silicon carbide, etc.) and natural abrasive grinding wheels and superabrasive (diamond and cubic boron nitride) grinding wheel;
Shape can be divided according to level grinding wheels, bevel wheel, cylindrical grinding wheels, cup wheels, disc wheel, etc.; binding agents can be classified according to the ceramic grinding wheel, resin grinding wheel, rubber wheel, metal grinding wheel. The wheel parameters are abrasive, viscosity, hardness, binders, shape, size and so on.
Since wheel usually work at high wood saw blades  speed, thus turning test should be carried out before use (guaranteed wheel at the maximum operating speed, not break) and static balance test (to prevent machine vibrations caused by the work). Grindstone at work for some time, should be trimmed to restore grinding performance and correct geometry.

Electroplated diamond tools, grinding wheels improvements

Electroplated diamond tool holding force exists insufficient particle shedding and other issues, has seriously affected the tool life and efficiency. This paper reviews the recent development of domestic and step pads  electroplated diamond tool performance improvement methods , grouped into the following three categories: one , improving coating matrix material properties, improve the coating and bonding of the diamond supporting role ; 2 , by increasing the diamond and the the contact area of ​​the carcass , to eliminate the gap between the diamond and the coating ; 3 , the diamond particle surface treatment , the coating is formed between the diamond and the chemical bonding . The text of the various methods are described in detail , there is potential for some methods are recommended to readers of electroplated diamond tools, improved methods have a comprehensive understanding of the system  Because diamond has a high hardness, high strength, high wear resistance and low coefficient of linear expansion and a series of excellent physical and chemical characteristics, are used to produce diamond tools for machining hard and brittle materials difficult to machine . Electroplating diamond tools prepared by  wall saw blades electrodeposition of metal , the consolidation of loose diamond particles in the plating layer, and the diamond particles have a cutting ability . Electroplated diamond tool manufacturers prepared low temperature to avoid heat loss of the diamond , and the production process is simple , less investment in equipment , the manufacturing cycle is short, convenient shape and can repair. Therefore, electroplated diamond products have a variety of grinding wheel, grinding , needle files , dig riving knife , trim wheel , geological drill bits, reaming, and external circular cutting disc , reamers, wire saws and other special tools, machinery, electronics, construction, drilling , optical glass processing and other industries widely used [ ] .
At present, prepared at home and abroad with electroplated diamond tools , the main problem is that the coating matrix metal and the binding force between the diamond particles is low, the use of diamond  wet granite pads particles by force , it is easy to fall off , resulting in short life. The main reason for these phenomena is prepared by electroplating diamond tool manufacturing low temperature, resulting in the surface of the diamond particles are difficult for the general metal infiltration, instead of getting a strong chemical bond , and often a gap . In addition, by the impact of the plating process , an optional type coating metal diamond tools limited ( only nickel, chromium and other small metals and their alloys ) , unlike the hot-pressing tool type of metal used as widely .
To solve the above problem, people used a variety of measures to address the diamond and the coating metal binding force . This article describes the comprehensive recent development at home and abroad electroplated diamond tool performance improvement methods , and they were categorized , I hope to give people a detailed and clear understanding.

Diamond Saw Blade cutting the amount of

In the stone processing, stone processing cutting costs account for about 50% of the total cost. At present, China's stone business is quite common to use diamond circular saws for the cutting device. According to statistics, the average per sawing 1m. Granite diamond segment consumes about 3-3.8 million, the power consumption of about 10 ~ 12kW.h, to China's annual use of diamond circular saw stone cutting 150 million m2 per  diamond grinding wheel annum gross consumption of diamond saw blades more than 500 million yuan, the total energy consumption by about 2 billion kw.h, thus optimizing the amount of diamond saw blades for cutting, reducing energy consumption, saw cutting consumption and improve the efficiency of far-reaching economic and social significance.
Diamond circular saw cutting costs affecting factors include stone composition, structure, physical and mechanical properties, equipment, technical performance, the blade cutting the amount of process performance and selection and other factors. Several factors in this regulation is only cutting the amount of artificial optional. Therefore, improving the stone sawing process is to reduce energy consumption, consumption and improve cutting efficiency saws to reduce the effective cost cutting measures.Grinding damage: the force effects and temperature than the response, after a period of use of the blade tend to produce wear damage. Grinding damage in  dry cut blades the form of mainly the following: abrasive wear, local crushing, a large area of ​​broken off, binders direction along the cutting speed of the mechanical abrasions. Abrasive: Diamond particles and constant friction formula pieces, into a flat edge passivation, loss cutting, increasing friction. Heat causes the cutting surface of the diamond particles graphite sheet, the hardness greatly reduced, increased wear: the surface of the diamond particles exposed to alternating thermal stresses, and also the cutting under alternating stress, fatigue cracks will be partially broken, revealing a sharp new edge, is an ideal wear pattern; large area broken: diamond particles in the Leads to withstand shock loads, the concrete cutting blade  more prominent grain and grain prematurely consumed; shedding: the diamond cutting force alternating binding agent particles are constantly being generated shaking loose. Meanwhile, the cutting process of the binding agent itself wear and cutting heat to soften the binding agent. This makes the gripping force decreased binding agent, when the particle is greater than the cutting force on the gripping force, the diamond particles will fall off. No matter what kind of wear and tear with the diamond particles to withstand load and temperature are closely related. Both of which are determined by Cheng cutting process and cooling lubrication conditions.

marble processing procedures

Marble composite panels, by definition is marble with other materials have been processed by the performance of the original marble plates. Specifically, it has the following characteristics:
①, marble composite board broken concrete drill bits  force of 258N/cm, more than 3 times stronger than the original plate.
②, no efflorescence yellowing: Because marble floor tiles and resin composite panels barrier layer of water and corrosive substances, eliminating the wet marble and cement paste after efflorescence yellowed common problem, wall stone can be directly wet paste, which hanging saving costs and reducing pendant hanging lugs and the space occupied by increasing the use of space.
③, Light weight: marble composite board panels and light weight than the original more than 2 times.
④, facilitate the construction: Marble tile composite panel construction method can be used instead of marble construction methods, so ease of construction, saving construction costs.
⑤, bond strength ideal: the tests show that the adhesion force: 91 N/cm2, specification is 600 * 600mm marble composite board 33 tons of gravitation would not be peeling.
⑥, heat resistance: marble composite panels soaking for a long time (120 hours) at 100 ℃ environment, no peeling, discoloration or other abnormal reflection.
⑦, low water absorption: marble composite plate on the back of ceramic tiles complete adhesion, the water absorption (0.13%) is low, less than 0.2%, not cracking.
⑧, smooth surface: marble composite board than the carbide tipped saw blade  original plate surface smoothness is very good.
⑨, low prices: As with a thin stick to the thick slab of marble tile, marble composite panels so the price is lower than the original board about 30%.
⑩, specifications and diverse: specifications for the 600 * 600mm and above, a variety of specifications marble composite panels husband or other specifications according to customer requirements of production.
Marble composite plate machining program
First select marketable grade marble varieties, and purchase specifications for 610 * 610mm blank tiles (ie not polished on the surface of the shaft tiles).
1. Sawing wool board: the marble blocks in the way cutting machine to machine to a thickness of 14mm, size 610 * 610mm wool board, then dry.
2. Bonding: The blank tile flat, face up, while the rough surface tiles and marble painted wool board side of the prepared adhesives, adhesive may be coated evenly and thin, uniform is all on the plate can not be applied to the left and uniform holes, otherwise it will affect sheet strength and fracture easily during grinding; book is suitable for bonding needs, just right, thick lead to waste and increasing sheet thickness. Then the hair is coated with the adhesive side down on the positive plate together with an adhesive in the coating on a rough tile; then again in the polished marble plates while the upper and the front of another piece of blank tiles coated thin wet saw blades  and uniform adhesive, then the other one is coated with adhesive on one side of the rough marble tiles together wool board, and then in the above press (available as a box of 10 weight 305 * 305mm sheet pressure at the top), after After more than 10 hours of consolidation, it becomes rough and down to the middle of the floor tiles marble composite wool board.
3. Of the profile: the top and bottom of the middle of rough marble composite tiles wool board mounted in the horizontal plane of the profile, right profile for the two side while the other side is rough marble tiles marble composite wool board.
4. Controlled thickness: Because marble composite wool board is made of marble, bonding agents and blank tiles composed of three, it is inevitable differences in thickness. Must therefore be controlled thickness. The marble composite marble wool board side up, thick machine controlled by controlling thickness to achieve the same thickness.
5. Polishing: After controlling thick marble and marble composite wool board up using ten continuous grinding and polishing, became high gloss marble composite wool board.
6. Cutting and chamfering: After grinding and polishing marble composite wool board cut by a cutting machine 600 * 600mm specification composite board, and then chamfered edges, became marble composite board products. Processed marble composite board finished thickness of 13mm, marble composite panel thickness of only 2 ~ 3 mm. The marble composite board finished packing, packing can be sold.

diamond tool section

Many different types of diamond cutting tools such as lathe, planer, milling and drilling tools, etc. They geometric shapes, varying degrees of complexity, but they are part of the structure and  green concrete blades geometry of the cutting angles have many common features, which are the most commonly used tools, the simplest and most basic cutting tools, and thus the most representative. Other diamond turning tool can be regarded as a combination or deformation. Therefore, the study of metal cutting tools, generally an example research and analysis tools.7.3.1 Composition of turning
Turning from the cutting portion, handle two parts. Cutting portion undertake machining tasks shank for clamping on the machine tool holder. By a number of side cutting portion of the cutting edge components. We used external turning tool is controlled by a nose, two cutting edges, consisting of three flank
1 flank
(L) on the tool rake face Aγ diamond chip flow over the surface;
(2) and the workpiece flank Aα cutting surface opposite to the flank;
(3) minor flank Aα the machined surface opposite flank.
 (2) cutting edge
(1) S before the main cutting edge rake face and the flank line of intersection, assume the primary cutting work;
(2) the secondary cutting edge rake face and the sub S flank line of intersection bears a small amount of cutting work.
(3) tip is the main and secondary cutting edge intersects the point, in fact, impossible to grind very tip of the point, but by a polyline or arc composed of tiny, tiny tip radius of the arc is called arc
Radius, expressed by rε
 7.3.2 diamond tool geometry reference system
In order to facilitate the identification of turning on the geometry, often choose a frame of reference as a benchmark by measuring the flank or cutting edge relative to the reference frame coordinate plane angle values ​​to reflect their spatial orientation.
Diamond tool geometry reference system there are two types, diamond tool mark angle reference lines and diamond cutter working angle reference system.
1 diamond cutter marked angle reference system
(1) Assumptions diamond cutter marked angle concrete saw blades  reference system is designed to mark the diamond cutter, grinding and measuring angles benchmarks defined in this basis, said diamond cutter diamond tool angle marked angle. In order to make the coordinate reference system with the sharpening plane, measuring datum consistent with the following assumptions special provisions.
Assuming motion condition ① with the main motion vectors instead of the relative motion vc approximate rate of synthesis vector ve (i.e. vf = 0).
② Assuming installation conditions require Arbor centerline and perpendicular to the feed direction of movement; tip and the center of the workpiece contour.
(2) Diamond point of reference annotation tool types according ISO3002/1-1997 standard recommends, diamond tool mark angle reference system with orthogonal planes of reference, the normal plane of reference and assuming that the work plane reference frame three.
① orthogonal plane of reference plane orthogonal plane reference system consists of the following three components:
Orthogonal planes of reference
Base pr is over a selected point on the cutting edge parallel to or perpendicular to the manufacture diamond tools, grinding, and the measurement is suitable for mounting or locating a plane or axis generally perpendicular to its orientation to the main movement direction of the assumed . Turning the base surface are parallel to its bottom surface.
Ps is the main cutting plane through a selected point of the cutting edge and the main cutting edge and perpendicular to the tangent plane of the base plane.
Po is perpendicular planes over a selected point of the cutting edge and perpendicular to both the plane of the base surface and the cutting plane.
Over the main and secondary cutting edge of a selected point can create orthogonal planes of reference. Base surface pr, the main cutting plane ps, is
Cross-plane po three planes perpendicular to each other in space. ② France France plane of reference plane of reference by the pr, ps and France plane pn components. Wherein the method is a planar pn over a selected point of the cutting edge perpendicular to the plane of the cutting edge
③ assuming that the glass blades  work plane is assumed working plane reference frame of reference by the pr, pf and pp components. Pf is assumed that the work plane through the cutting edge parallel to a selected point and the assumed feed motion perpendicular to the plane of the base plane. Back plane pp is over a selected point of the cutting edge perpendicular to assume that both the feed movement and the plane perpendicular to the basal plane. Marked diamond tool design, grinding, the most common is the measured angle orthogonal planes of reference.
1 diamond cutter working angle reference system
Working angle diamond tool diamond cutting tool reference system is working angle reference (without regard to assumptions), as defined in this basis, said diamond cutter diamond tool angle working angle. It also has orthogonal planes of reference, the normal plane of reference and assuming that the work plane of reference.

diamond cutter trimming scope

We usually use the knife at home, not agile, and will look for stones to grind it, not agile how diamond tool repair? In the dressing precision grinding wheel diamond tools (such as internal grinding), you should use a sharp diamond shaped stone, diamond tool if a large  concrete crack chaser amount of high-precision grinding wheel, we recommend using a spherical diamond larger contact area in order to ensure that from fine grind to a coarse trimming range.
Small blade cutter and other cutters classes are primarily used in the following hard metal materials processing or narrow and deep grooves cut milling can also be non-metallic, superhard materials and titanium blade cutter blade cutter main used for cutting hard materials (heat-resistant steel, stainless steel, high-strength steel) milling.
  Carbide blade carbide (more precisely, tungsten carbide and titanium carbide) is a cutting tool of any kind are common materials: for example, saw blades, lathe tools, drills, milling cutter and  cbn grinding wheels dental drill engraving are generally made with carbide. The reason is widely used in such carbide tool, because it is with most other materials remain sharp longer. In addition, some carbide ball pen use, because the pen is more durable.
 Carbide blade eventually become dull. You can be as polished as ordinary steel tools grinding them, but they are very hard, so you want to use a different grinding tools. Usually a diamond coated cemented carbide tools or wheels.
 Diamond Segment Features: Blade's work performance is extremely good, especially in the granite cutting speed, long life, straight cut, do not jump edge, etc. Various specifications can be customized according to customer requirements.
The chemical composition of the sds plus drill bits  diamond C, with the carbon and graphite polymorph variants. In mineral chemical composition, the total content of Si, Mg, Al, Ca, Mn, Ni and other elements, and often contain Na, B, Cu, Fe, Co, Cr, Ti, N and other impurity elements, and carbohydrates.

discusses the diamond wheel diamond place

Transition index equal to the diamond saw blade   diamond layer adjacent to the substrate secure in the sector. Our base for 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 transition layer. As long as the task layer is called the diamond layer, the masonry blades   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 diamond core drills  arrived with its most empty thinking is to see consistent use of materials abrasive. Its primary organs are made of metal powder, resin powder, ceramic and metal plating as liaison agent.
