Maintenance of the blade:
1 blade If not used immediately, it should be flat or use the hole to
hang up, or other items can not be stacked on the flat of the blade
foot, and pay attention to moisture, anti-corrosion.
(2) When the blade is no longer sharp cutting surface roughness, it
must promptly re-grinding. Grinding can not change the original angle,
and destruction balancing.
3 inner diameter of the blade correction, the positioning hole
machining, etc., must be performed by the manufacturer. If the process
is bad, will affect the product effect, and potentially dangerous,
reaming should not be over the original aperture 20mm, so as not to
affect the balance of stress.
Blade requirements:
1, when the work piece should be fixed to ensure that, in line with
eating knife profiles positioning direction in order to avoid abnormal
cut, or not to apply lateral pressure curve cutting, smooth feed to
avoid the impact of the blade contacts the workpiece, resulting in
blade breakage, or workpiece flying, accident.
2, work and found abnormal sound GUSHI sanding disc for drill and vibration, cutting surface
roughness, or odor, you must immediately terminate operations, timely
inspection, troubleshooting to avoid accidents.
3, at the start and stop cutting cutting, do not feed too fast to avoid
broken teeth and damaged.
4, if the cutting aluminum or other metal, to use a dedicated coolant
to prevent the blade from overheating, resulting in tooth paste, and
other damage, affecting the cutting quality.
5, flutes and suction equipment to ensure smooth flow of slag device to
prevent slag accumulation into blocks, affecting production and safety.
6, when dry cutting, do not cut long GUSHI tct circular saw blades hours, so as not to affect the
life of the blade and the cutting effect; wet sheet cutting, water jet
cutting should be added, to guard against leakage.

Status of high-grade blade matrix diamond saw and development prospects
Diamond saw blade is now widely used in the construction of stone, glass, ceramics, crystals, gemstones, iron and other materials processing and housing, roads, bridges, etc., with the continuous improvement and cost diamond saw blade production technology continues to decrease, it applications is still expanding, the demand continues to increase, now it has become an important part of diamond tools, diamond is the largest consumer of diamond tools. Diamond saw blade production methods and their GUSHI dry cut blades application of the effect of different production methods and application performance saw blade, the method currently used mainly to suppress the production of sintered diamond saw, a few blades produced using electroplating method, there is a common method of cold pressing and sintering sintering, hot pressing and sintering welding three main ways. Saw another frequency welding welding and laser welding points.
Currently, in the international market, there is still a monolithic saw a higher share, while the domestic market are based on a combination of multi-chip saw blade thickness of the same group saw a different diameter, this group saw blade on the saw and requirements are high, high production efficiency, but the production cost is high. But the group saw less demanding on the diamond saw blade sharpness, and past monolithic saw a substantial increase compared to the production efficiency, but also reduces the overall cost, which greatly improved the international competitiveness of Chinese-made stone. Trimming Saw prevalent in Ф300mm to Ф500mm welding-type blade, the international market for such demanding blade sharpness, taking into account the life of the saw blade and prices, the domestic market is too much emphasis on price, and thus the blade performance than Low. Saw a lot of modeling classes used in Japanese tombstone machining and interior decoration to GUSHI tct circular saw blades the small size of the main blade Ф350mm below. Various methods are currently producing blades are in use, but still hot pressing the blade as much. In addition, according to the type of stone blades have marble, sandstone blades, granite blades and artificial stone blades of the points, the largest granite blade consumption, but high-grade marble cutting edge blade technology the highest degree of difficulty, artificial stone blade demand is gradually expanding.
Construction is second only to diamond stone tools the second largest diamond tools diamond tools, the Western developed countries especially the United States very early use of diamond tools in engineering construction, to the present has been very popular and formed numerous varieties. On diamond saw blade variety, from the use of equipment or processing or use of objects such as different angles classification, this article will be divided into general simplify blade saw, saw blades and other specialty blades, blade and then classified according to the professional processing of objects , a common old concrete saw, saw blades new cement, asphalt saw blade, wall saw blades
Diamond saw blade in a wide range of GUSHI stone drill bits applications in developed countries, more mature technologies and standards, product and market segments have been, but with the further development of the technology of diamond saw blades, diamond saw applications will continue to expand, the market will continue to grow. Diamond saw domestic market has become the world's largest market, but aspects of the blade level, variety, range of applications and manufacturing technology there are still a wide gap with developed countries, regardless of technology or the market has much room for development, I hope the industry ambitious people to continue their efforts to eliminate the gap as soon as possible.

Diamond wheel clogging type description
1 ) embedded clogging mechanism and attachment type
Embedded and dependent type jams are clogging debris mechanically filling in gaps in diamond grinding wheel produced . Fill power from two aspects, one is external , one internal, related to the physical, electrical , thermal , etc. factors.
External factors : Grinding has a very important feature , so the grinding zone of debris under strong positive pressure is mechanically squeezed into the gap in the wheel surface . From the microscopic analysis of debris along the front of the slide abrasive , abrasive in front brick saws of the local area with several layers of debris piled in the back of abrasive due to the role of high-speed rotating grinding wheel , forming a vortex flow area, whirlpool area significantly reduced air pressure in the negative pressure , so that part of the debris attached to the back of the abrasive grains to form abrasive flank dependent clogging material is attached to the majority of ash and particles. Electrostatic field : the relative speed of the grinding wheel and the workpiece is much greater than V V sand workers, ordinary grinder V s = 3 ~ 50m / s, the speed of high-speed grinder grinding maturity value is 50 ~ 80 / s, foreign trials at speeds up to 1.5m / s or less 200m / s ~ 250m / s, the speed of the workpiece . When the grinding wheel and the work of the relative motion , arranged according to certain rules of the charge in the grinding area, due to the grinding wheel and the workpiece surface electron escape will cause. Meanwhile , the grinding gas high temperature region will result in the shock due to the discharge , so that the neutral abrasive flap wheels gas is ionized into positive ions and electrons. Some small areas in the grinding zone formed by a small electric field consists of the grinding wheel and the workpiece , the electric field , neutral atoms , positive ions, electrons , impurities, dust , not only the neutral atoms are ionized in the process , there are ion and electron recombination process. In the electric field , the polar part of the debris will be presented according to the principles of opposites attract , and the wheel opposite to the polarity of the debris is adsorbed on the surface of the grinding wheel . Since the electric field strength is small, so the adsorption force is weak, the wheel surface debris is not solid , but by means of mechanical pressure between the larger wheel and the workpiece, the wheel has been adsorbed on the surface of the wear debris can be stably embedded Wheel the gap between the surfaces . 2 ) blocking adhesion type mechanism : the majority of the grinding process of grinding the input power into heat, so that the grinding temperature up to 1200K or more points , in such a high temperature, rapid grinding of the first case of air circular blades oxidation , the formation of low melting point metal oxides, metal oxides followed by those in the grinding zone was heated to high temperatures melt state , covering the surface of the wheel , when this part of the surface of the grinding wheel on participation once again in the role of the grinding force , and some squeezed open , some enhancement, increased affinity and adhesion with the wheel , and the workpiece is pressed adhered to the surface of a groove surface of the ridge . Through multiple stochastic grinding , many abrasive debris adhering four weeks , the grinding force increases, the temperature rises , thereby forming a vicious cycle of increased congestion, or the abrasive grain broken off, which is melt adhesive .
