wheel speed hazards arising from the work
Not only cause wheel breakage near in death or serious injury, but can also cause serious damage to the plant or housing. Although the manufacturer has taken various preventive measures, but if used carelessly careful wheel still occur occasionally break or crack accidents. Applications to take the following precautions concerning:1. Handling and diamond bandsaw blades storageIn shipping and handling process, if moisture enters phenolic resin bonded grinding wheel, it will reduce its strength; ceramic bonded grinding wheels and, then very sensitive to temperature changes repeatedly; uneven absorption of moisture causes the wheel out of balance . Therefore, in the loading and unloading wheel must be handled with care, and to be placed in a dry and sheltered place, in order to maintain the grinding wheel normal state.2 crack detectionDeal with the new wheel checked to ensure drying and grinding wheels from 9 inch saw blade damage. The easiest way is to tap the wheel with a mallet. Intact ceramic grinding wheel will be issued by the crisp sound. Wheel with an organic adhesive bond will be issued muffled sound, but with a defective wheel crushing sound is emitted distinction. For suspected wheel, they should check that the delivery person.3 TestOfficial use of the new wheel should be performed before full trials and should be carefully observed. In the Diamond tool wet, the wheel should be idling for some time, get rid of the water. Otherwise, the water will accumulate in the lower part of the wheel, causing the wheel imbalance, resulting in next time may burst.

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.

Where natural single crystal diamond (Single Crystalline Diamond, SCD) cutting edge parts by high magnification 1500x still observed blade smooth. Ra SCD when turning aluminum pistons reach 4μm, and in the same conditions using PCD cutting tool machining time of the surface roughness Ra of 15 ~ 50μm. So the cutting discs use of SCD tool with precision lathes for precision and ultra-precision machining, get the mirror surface.
Polycrystalline diamond (PCD) cutting tools
PCD is a high temperature high pressure conditions by cobalt and other metal-bonded to synthetic diamond powder sintered polycrystalline material gathered, also known as sintered diamond. Overall sintered polycrystalline diamond cutter cutter for milling, PCD grain was disordered arrangement state, is isotropic, uniform hardness, graphitization temperature is 550 ℃. Tool has high hardness, high thermal conductivity, low thermal expansion coefficient, high elastic modulus and a low coefficient of friction. They are very sharp and so on.
Synthetic polycrystalline diamond compact (PDC) cutter
In order to improve the toughness of PCD inserts and weldability, often made of PCD and carbide cutter body synthetic polycrystalline diamond composite blade (PDc). The surface of the cemented carbide substrate being suppressed 0.5 ~ 1mm thick layer of sintered PCD. The flexural strength of the composite blade with carbide consistent hardness close to PCD, PCD can replace the use. PCD and synthetic polycrystalline diamond compact (PDC) cutter sharp edge and workpiece surface quality than ND. While its workability is poor, the grinding ratio is small, it is difficult according to the turbo diamond blade geometry of any head shape. Current use of synthetic polycrystalline diamond compact Preparation Tool only, still can not be manufactured with chipbreaker indexable inserts and complex three-dimensional surface geometry cutter.

diamond tool wear
Diamond tool wear mechanism is more complex, can be divided into macro-and
micro-abrasion wear, the edge polishing pads 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 diamond blade wear to the grinding tool to meet the
requirements, but if the wear generated may damage not have a good grinding
before the flank. The edge cracking (i.e. chipping) is on the edge of the local
stress exceeds the capacity of the 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 concrete core bits vibration of the tool
blade and grinding wheel grit the mouth of the impact of the role, it is often
accompanied produce chipping.

planes of single crystal diamond tool selection
Diamond crystals are cubic plane, since each crystal form and surface atomic
arrangement atom density difference and the diamond cup grinding wheel distance between the different
planes, resulting in a natural diamond crystal anisotropy, so the performance
of the diamond crystal surface only of the physical and mechanical different
performance, ease of manufacture and service life which are not the same, the
microstructure of the crystal surface damage strength are also significant
differences. Microscopic diamond crystals Hertz strength test method used to
determine, since the diamond is a typical brittle material, the strength values
are generally larger deviation depends on the morphology and distribution of
stress distribution range, so suitable analysis of probability theory. When the
effect of stress is the same, (110) crystal plane maximum probability of
damage, (111), followed by (100) crystal plane of the minimum probability of
breakage. Ie external force, (110) crystal face the most easily damaged, (111)
crystal face, followed by (100) the most difficult to break. Although the (110)
crystal plane grinding is higher than the diamond polishing pads (100) crystal plane, but the
experimental results show that the (100) crystal face and the other plane has a
higher resistance to stress, corrosion, and thermal degradation capability.
Considering the combination of micro-strength, a (100) plane around the flank
of the tool to make easy tool edge grinding of high quality, easy to produce
microscopic chipping.
Normally be carried out according to requirements of the tool planes of the
single crystal diamond tool selection. In general, if the request to obtain the
highest strength diamond tool, should be used (100) surface as the tool before
the flank; if required resistance to mechanical wear diamond tool, the
selection of (110) crystal face as the tool before and after the diamond blade saws flank; if
required chemical wear resistant diamond cutting tool, it is desirable use of
(110) crystal plane as the tool rake face, (100) crystal face as the flank, or
the front, flank are used (100) surface. These requirements are necessary to
achieve by means of crystal orientations.

diamond saw Introduction
After pondering the diamond is a diamond, diamond is a natural mineral, is a rough diamond. Simply put, diamonds deep in Earth pressure, high temperature conditions to form a composed of carbon elemental crystals. Although human civilization thousands of years, but it was discovered and the initial understanding of the diamond is only a few hundred years, and really uncover the mysteries within the diamond blade saws even less time. Prior to this, it's just fabulous along with religious worship and fear of the legend, while it as brave, power, status and dignity of the symbol. Today, diamonds are no longer mysterious, but not only can enjoy the royal treasures. It has become the people they can have, wear mass gems. Diamond's culture and diamond core drills long history, more people today see it as a symbol of love and loyalty.
