diamond segment of the optical properties of diamond

  (1) The brightness of the optical identification (Brilliance) because of the diamond has a very high reflectivity of the  reflection critical angle is small, a wide range of total reflection, total  14 inch saw blade reflection light is easily reflected light is large, resulting in high brightness.
(2) Flashing (Scintillation) is flashing diamond flash, that is, when the diamond or the light source, the observer moves relative to the surface of the white light reflection and flash. Colorless, transparent, well-crystallized poly octahedral shaped diamond surface bodies or, if not Gache grinding can expose good flashing light.Depends not only on the diamond bandsaw blades  performance of the blade diamond, but on the diamond and the binder with the appropriate head of this composite material composed of the overall performance. For marble and other soft stone, head of the mechanical properties required is relatively low, the choice of copper-based binder. The sintering temperature is low but the copper-based binder, strength, low hardness, high toughness, low bonding strength with the diamond. When adding tungsten carbide (WC), the WC or W2C to as a skeleton metal, with the amount of cobalt in order to improve the strength
(3) the dispersion or the wet granite pads  fire (Dispersion or fire) planes of diamond as diverse as prism, can through refraction, reflection and total reflection into the interior of the crystal composition of white light into white color - red, orange, yellow, green, blue, indigo, violet shade.
(4) Gloss (Luster) outstanding diamond-like hard, smooth and bright crystal face or cleavage face in white light reflection effect particularly strong, and this is very characteristic of the role of reflective called adamantine luster.

How to determine the level of diamond saw blades

In general, diamond saw blade working environment is bad, products are mainly used for sawing stone, widely used in marble, granite, ceramic tiles and concrete products for cutting, is stone, building industrial saw blades  materials industry, an important and widely used processing tools.
Circular saw blades cutting with easy operation, high efficiency, good processing quality and other advantages. But noisy, blade rigidity. Easy to produce during cutting blade runout, deviation, resulting in the parallelism of the workpiece to be cut is poor. Saw cutting spindle bear a large force, the swing generated during the cutting, but not cut out straight, the blade thickness can be increased despite increased rigidity, it is  diamond polishing tools still difficult to ensure parallelism of the slice. In addition, the increased thickness of the blade not only increases costs, but also increases the kerf width reduces the volume ratio. Cylindrical cutting line speed is higher, up to 50m / s, the diameter of the saw blade cutting depth by limiting, usually less than the diameter of the third. Currently, the cutting depth is generally not more than 1 meter. The  carbide drill bits most critical quality diamond saw blade with diamond granularity necessary, which is testing the wear resistance of diamond saw blades and sharp the most important indicators.

CVD diamond excellent performance

CVD diamond as a cutting tool material favorable conditions for its unparalleled hardness is caused by the combination of excellent properties. With metal sintered PCD different is the unique nature of natural diamond in CVD diamond have been retained, even at high cutting temperatures also do so. Single crystal diamond hardness and  grinding cup wheel elastic modulus of a good result of CVD diamond wear resistance and dimensional stability.The silicon carbide "sand" test, the independent relative volume loss of CVD diamond PCD lower than 4 times, and 120 times lower than that of tungsten carbide. And metal bonding is not the same PCD compact, thick CVD diamond single crystal diamond material with high cutting temperatures in hardness and wear resistance comparable to or even exceed the single crystal diamond cutting at high temperature hardness and wear resistance Like the natural diamond CVD diamond has a small coefficient of friction generated during cutting and  concrete vibrator can consume a small cutting forces and less friction resistance and excellent heat resistance chip tumor.In dry cutting or high-speed machining, the high lubricating properties of CVD diamond cutting temperature resulting reduction of its superior PCD and other materials, the main favorable conditions. CVD diamond thick film applied to the mechanical aspects of the thermal conductivity of CVD diamond material is tungsten carbide efficiency five times higher thermal conductivity than the PCD 50%. CVD diamond excellent thermal  turbo diamond blade conductivity can be used as a safe route cooling the cutting area. Non-adhesive structure allows CVD diamond tool machining withstand temperatures up offensive 800 ℃, while cobalt sintered PCD when machining temperature close to 700 ℃, it will be heat damaged. Although the PCD can be filtered to prevent cobalt cobalt way resulting decline in the quality of PCD, CVD diamond but also has excellent wear resistance. With metal sintered PCD and tungsten carbide materials, non-binder structure and chemical properties of CVD diamond is more stable. CVD diamond coated cutting tools with synthetic materials such as phenolic resin polymer corrosive obviously has a longer life, CVD diamond cutting tool also against fluid corrosion.

Various uses circular blade

circular blade which extensive use? We usually see mostly circular blade forming entities, not knowing its composition and purpose, only those who know the composition of the circular blade, it  diamond bandsaw blades can be handy to use, after problems, but also to find the appropriate solutions under normal circumstances round blade is mainly used for paper, film, gold, silver, copper and some light cutting the article. That some requirements on the blade, the blade is smaller resistance, wear resistance, higher precision for the goods! Accuracy requirements for the blade, and sometimes required to achieve micron-level precision, because it involves the use of the tape to the information industry, requires  4 inch circular saw blade a realistic reproduction of sound and image is an important condition.
In the circular blade manufacturing process, slitting knives, the accuracy of the tool holder will affect the accuracy of the tape cut, which latter sense and FIG sensitive products, has a very important effect, we have also ultrafine particles of tungsten carbide and The most advanced precision machining precision constant pursuit of the technical aspects, I hope cutting blades  can do better late.
About the cutting blade has its own statement, in general, the upper and lower blade will cut widely used in wire and cable, rubber, aluminum, chemical fiber, non-manufacturing cloth, paper, paper products processing, adhesive tape products, films, composite packaging materials, telecommunications appliances, cigarettes, leather, printing, food and clothing industries. This application is very broad, but also ensure the application diversity.

saw blade is a good high-grade alloy

Now many users for woodworking saw blade alloys have a misunderstanding that alloy saw blade that must be considered a good big saw blade , be considered professional woodworking saw blade . In fact , the fact is not so.
You know, alloy saw two of the most important  concrete saw blades conditions : First, need a good base . Second, the need for high -quality high-grade alloy head .
Imagine a low- grade alloy head even more another big or low level , and can not increase the sharpness of the blade , precision. So head low grade broadsword broadsword with a high level of head is not necessarily proportional . Alloy saw blade is always high grade alloy head , that does not necessarily means that the sword head like.
Broadsword heads are distributors and diamond blade saws  manufacturers making some gimmick, I believe that many users use low grade broadsword head alloy blades will know, in fact, can not be the perfect solution to cutting issue . Of course, high-grade broadsword head on exceptions it. Scope: the cutting carbide up 300mm/min, marble cutting up 100mm/min, flower diamond cutting up 40mm/min, is the traditional reciprocating saw or wire cutting efficiency several times , and its narrow cut ( only 1.2mm ~ 2mm), with grinding cup wheels  traditional reciprocating saws and circular saws can be saved compared to 6 to 10 times the processing of raw materials , the user can bring significant economic benefits , these advantages are the traditional reciprocating saws , circular saws can not be compared the .

With what blade cutting plywood

As users have become increasingly demanding and industrial , but also in the field of homeopathy cutting plywood born professional plywood blades. It is generally used plywood blade outer diameter grinding cup wheels  of the saw blade specifications are 250,300 , usually teeth in 80T, 100T, 120T. That in the end Plywood Saw What difference does ?
Traditional plywood blade for general use around the tooth , so cutting efficiency and speed, but only applied to less demanding cutting plywood processing . So professional plywood blade adjustments according to market demand toothed blade and cutting efficiency .
 First, the choice of the cutting blade should choose chrome or nitrided HSS film , some saw after deposition , the diamond blade saws  steel plate heated and deformed or even beat way through the steel sheet flatten again after cutting Poetry time will again deformed steel , chrome HSS film is specifically designed for stainless steel characteristics for stainless steel cutting .
Second, the cutting machine 300 or more should be selected models, the power can not be too small , the choice of  core bits for concrete the cutting speed , the workpiece to be cut should be based on the type of cross-section and toughness to be. Higher cutting speed , cutting the temperature will be higher. Toughness of the material , the speed slowly ; workpiece cross-section is relatively large, then the speed should be slow . Finally, the cutting temperature will have a great time , cutting fluids, cooling, lubrication and cleaning of the choice of cutting results also play a significant role. The cutting fluid used are mineral oils, vegetable oils , emulsions , etc. , depending on the selected parts for cutting fluid.
