grinding fluid supply requirements more effectively

By spray method for increasing the pressure (1MPa above), increasing the grinding fluid jet velocity, airflow speed rotating grinding wheel broke, the grinding fluid flow into the grinding zone  diamond blades effectively, rapidly remove heat, improve the grinding effect. Used cylindrical grinding nozzle structure, the use of nozzles spaced high-speed airflow baffle will ensure the smooth grinding fluid injected into the grinding zone, while preventing grinding fluid splash.
 When the wheel speed is high, the wheel periphery airflow also strengthened, then you can take appropriate measures, such as adjusting the grinding fluid nozzle orientation. In the air force concrete diamond blades  jet force and effect, so just grinding fluid is injected into the grinding zone; mounting angle of the nozzle spray liquid should just make some up blocking airflow, partially into the grinding zone. Furthermore, you can increase the injection pressure and grinding fluid injection amount, reducing the increase of the nozzle outlet cross-sectional area and the nozzle width.
 High-speed grinding, grinding fluid supply requirements more effectively, use reflective supercharger. When an ordinary pressure grinding fluid from the tube into, sprayed onto the wheel surface through holes, grinding fluid speed centrifugal force is reflected back diamond core drills  booster bottom. The bottom of the grooves and ribs, grooves and the grinding fluid turbulence vortex, at the top of the convex rib dynamic pressure generated from the surface toward the wheel washing action, the cooling effect is significant flushing. The gap of the grinding wheel surface ribs equals 1.5 ~ 5mm.

What are the current market and diamond tools

At present, China's use of abrasive machining, geology drill and stone cutting tools manufacturing technology level has been greatly improved, the product has formed, standardization, variety specification is complete, stable product quality, some products in the  diamond blade saws international market certain competitiveness. All kinds of diamond tools also been widely used in various industries, and achieved significant economic benefits, but on the whole diamond tools industry, still need to improve the industrial planning, broaden application areas, creating an international brand.
1 Industry Planning: strengthen macro-control management
Because the blind development, hardware and tools, especially diamond tools production layout appears scattered and  masonry saw blades  chaotic situation everywhere, generally small-scale producers, production is not centralized, process technology, the lack of market competitiveness, product quality tools sales market instability, competition disorder, price confusion, economic efficiency is not high.
(2) Product Development: Widening the application areas of diamond
The current domestic production tools as well as new product development, technology research and other aspects of insufficient capital investment, to increase tool industry investment, pay close attention to new product development and new technologies, promotion of new technology and continue to broaden the field of application of diamond to enhance diamond tools industry overall technological level and market competitiveness, variety, quality of survival, to scientific and technological progress and development.
Tools to meet the needs of the diamond core drills  market at home and abroad, we must accelerate the development of new products, improve product quality, increase product variety and improve production. In recent years, machinery, gems, medical equipment, wood, glass, steel, stone handicrafts, ceramics and composites processing of non-metallic brittle materials the field of diamond tools demand increases every year, at present, these products are domestic or imported, must as soon as possible developed a variety of high-quality range of tools to replace imports.
Currently urgent need to develop products: oil drilling PDC bits, stone polishing with diamond grinding blocks, core bits, diamond honing stone, diamond film coating tools, diamond wheel, rubber plastic-bonded diamond tools, PCD diamond tools, diamond needle, nozzle, diamond heat sink and transistors and other products. To ensure the quality of their products, we must accelerate new technologies, promotion of new technology, such as vacuum welding technology, spark sintering technology, uniform technology of diamond, diamond-plated iridium technology and metal bonding technology, laser welding technology.
3 development of the industry: joint build international brands
Enterprise, innovation is advanced technology, and constantly improve the production process, reduce production costs and improve economic efficiency. Take the group or joint venture on the road, the formation of several large enterprise groups, to guide development of the industry, to create their own brand, and actively participate in international competition. Relying on technological progress, increase scientific and technological input, update equipment, pay close attention to new technologies, new processes, new product research and promotion, to improve tool substrate material usage, accelerate the development of China's hardware tools industry to further enhance economic efficiency and overall level of technology.

film diamond

 Diamond film synthesis technology and applied research on a global scale has grown rapidly, forming a "diamond film hot." In ten years, the development of gas-phase synthesis method to twenty kinds, general hourly rate of deposition is only 1 ~ 2um, how to accelerate the  deposition rate has been one study. Recent developments in the deposition rate to 100um / h or more, up to 930um / h. We call thick diamond. Diamond is a pure diamond thick, close to the hardness of natural diamond, and PCD, PCDN diamond powder is mixed with the binding agent is sintered, so by the binding agent of the concrete diamond blades  hardness, the hardness as the former. China has successfully mastered this technique, the maximum sediment thickness reaches 2.3mm. Has now been commercialized into the international advanced level.
PCD diamond thick film is that no different from the binding agent, is a pure diamond, the diamond core drills  higher its hardness, and natural diamond different, it has isotropic, low cost, so in many respects replaced PCD. Will be used for wire drawing dies uniform wear, so much better than the quality of the wire wire drawing natural diamond dies. If the deposition further improve the quality in ultra-precision machining is also the possibility of replacing natural diamond, the field of ultra-precision so popular attention.
In short, diamond and superhard materials as superior performance, application constantly expanding, from the developed to the  cup grinding wheels metal processing optical glass processing, stone processing, ceramics processing, processing of brittle materials is difficult for traditional processing areas, for a variety of industrial development will play a huge role in promoting broad prospects.

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.
    How the diamond wheel on three disjointed comprehensive alone. Like a corporate team, this three Qianan choice with a good grade diamond wheel diamond place.
