In recent years, micro-V-grooves have been designed on optical fiber docking, medical cell analysis and photovoltaic lamp substrate, which can produce new functions such as micro-fiber array positioning, micro-cell guidance and so on. But these high value-added substrates are mostly hard and brittle materials difficult to process. It depends on the low efficiency and high-cost method of chemical and chemical etching. In this study, it is proposed that the fine precision dressing with V-tip of fast 9'' grinding wheel is the key technology to ensure the degree of fineness.


In the research, the V-tip of the diamond grinding wheel is dressed by NC grinding and contact discharge technology, and the feasibility of micro-dressing is analyzed. Furthermore, the inspection and evaluation model of V-tip angle and tip arc radius is established to study the factors affecting the forming quality of V-tip of the diamond fast 9'' grinding wheel, and the dressing accuracy and efficiency are analyzed experimentally.


First of all, NC grinding technology was used to repair the V tip of a diamond grinding wheel and the machining experiment was carried out. The experimental results show that the radius of the V-tip of the SD600 diamond fast 9'' grinding wheel can be less than 20 microns, and the fine diamond particles on the V-tip can be sharpened, which can be used in micro-grooving. When machining monocrystalline silicon, the radius of the microgroove corner is 28.3-micron m, and its aspect ratio is 0.20. In addition, the shape of the V tip micro abrasive has a great influence on dressing efficiency and machining accuracy. Compared with # 180GC oilstone dressing, using # 600GC dressing can get better micro-abrasive edge appearance, and improve material removal rate about three times in micro-groove processing, but the dressing rate is reduced by 6-7 times. Thirdly, the V tip of the metal bonded diamond fast 9'' grinding wheel was repaired by contact discharge.


It is found that when the discharge voltage is 7V and the discharge frequency is 500HZ, a better forming angle and a smaller tip arc radius can be obtained; the dressing rate of contact discharge dressing is about 350 times that of # 600GC rubble dressing, and the dressing efficiency is about 59 times that of # 600GC rubble dressing. Finally, the V-shaped tip of the dressed fast 9'' grinding wheel is used to fabricate micron-scale groove arrays and pyramid spatial arrays of cemented carbide turning tool head, optical fiber butted quartz substrate, SiC ceramics and WC cemented carbide substrate. The experimental results have shown the application prospect, which provides a theoretical basis and basic parameters for the application of V-tip diamond fast 9'' grinding wheel in micro-machining.

Here we share the advantages of diamond fast 9'' grinding wheel than manual grinding.

Today I will teach you the advantages of diamond grinding wheel grinding than manual grinding, I hope to help you in the future can be used, please follow the small edition to understand the following content.


Because of the high speed and low heat dissipation time, the wear rate of diamond high quality 9'' grinding wheel is large. This is because the diamond abrasive is poor in heat resistance and easy to carbonize, but in manual grinding, because of the low grinding speed, the wear of diamond abrasive decreased. This is due to low grinding speed, long heat dissipation time and low grinding temperature. It can be seen that diamond abrasive is not only high in life but also economical in low speed manual grinding.


The diamond grinding wheel rotates at a certain speed and rubs across the contact surface of the two electrodes at a certain pressure. At the same time, the grinding fluid is sprayed into the contact surface between the two electrodes and the grinding wheel. When the power supply is switched on, the contact discharge between the electrode and the diamond grinding wheel occurs, thus causing the discharge erosion of the metal bond of the grinding peak and the diamond. The stone particles are partly exposed and prominent. In this way, diamond grinding wheels can be repaired.


The advantages of diamond grinding wheel made in China over manual grinding are described above. Our company is engaged in diamond grinding wheel industry for more than ten years. We have rich production experience and 100% guarantee of product quality. If you need to consult or purchase, you can call our service hotline.


Fast high quality 9''230*6*22mm grinding wheel for stainless steel is widely used in all kinds of construction industry, it is used to grind the stainless steel, carbon steel, and iron. 


Before we take the order, we first will ask customers some questions.


The first question is about the application, we will ask them what material do they want to grind by using the fast 9'' grinding wheel. Actually, to grind iron, carbon steel and stainless steel, there is big difference, if you want it to grind iron, we can produce it more suitable for iron, if you want it to grind carbon steel, we can produce it more suitable for carbon steel, if you want it to grind stainless steel, we can produce it more suitable for stainless steel. We will have to change the rate of the material during the blending to meet your demands, or change the raw material from the source. 


The second question we will ask customer is what sizes do you want, if the sizes are common seen and standard size, there will be no need to worry, while if the sizes are not common seen and new to us, we will have to order the new model for the new grinding wheel made in China For example, common seen 9’’ grinding fast grinding wheel for stainless steel is 230*6*22.23, while if you want it 230*6*25.4, it is a new size, it is not common seen, we will have to open new model for it. 


The third question will be the quantity you want, if you order more than our MOQ, there will be no problem and we can produce it according to your quantity, while if your order is less than our MOQ, we will have problem to produce it for you, for example, if our MOQ is 10000, but you only ask for 5000pcs, there will be a problem for us to produce for you, actually we can produce, but the problem is that there will be unqualified fast grinding wheel for stainless steel produced, we need to destroy the unqualified products, maybe the unqualified fast grinding wheel for stainless steel more than what you need, and if we open our machine, maybe the first two hours we are just doing the adjusting and excising work, the third hour will start the real work, within 30 minutes, all the products have been produced, no more need this machine, our workers will be very sad, they have worked too much time for the adjusting, while producing just takes 30 minutes, they can only earn very little money, they are unwilling to do that job.
