Diamond grinding wheel is a relatively cold product, the use of industry and equipment is relatively small, but for the need of its equipment, we have to understand. What is diamond grinding wheel, it and alloy grinding wheel what is the difference? Here is a small part to give you a detailed introduction.
Diamond grinding wheels are used to grind a variety of special tools and CNC inserts. Diamond is a high strength sharpening tool, is the raw material for the production and processing of a variety of special tools and CNC inserts. Diamond grinding wheel is a special animation tool for cutting cemented carbide, laminated glass, porcelain and crystal contour line.
In recent years, with the rapid development trend of rapid cutting and high-precision cutting technology, more requirements for grinding wheels have been put forward. Metal material fusion grinding wheel is widely used in manufacturing industry with its remarkable features such as high bond strength, good formability and long service life. According to the different methods of diamond grinding wheel manufacturing, there are two key technologies:calcination and electroplating.
The difference between diamond grinding wheels and alloy grinding wheels:Generally speaking, the alloy refers to cemented carbide, and the grinding wheels for grinding cemented carbide are emerald green carbon-carbon composite grinding wheels. Compared with diamond grinding wheels, the strength of silicon carbide grinding wheels is not as high as diamond grinding wheels. Before there is no diamond grinding wheel, diamond green carbon carbon composite grinding wheel is used to grind carbide CNC inserts. Now there is a diamond grinding wheel, many people use diamond grinding wheel to grind carbide CNC inserts. And carbon-carbon composite grinding wheels are the key grinding wheel type for grinding carbide CNC inserts.
In daily applications, many operators are always accustomed to the actual operation on the grinding wheel because they can work very hard in this position. In fact, this practice is a personal behavior that should be especially prohibited in the actual operation of grinding machines. According to the safety operating procedures, when using the grinder to cut product workpieces, the operator should stand on the side of the grinding wheel and should not perform the actual operation on the front side of the grinding wheel to prevent the wheel from flying out or being crushed and flown out, causing injury.
Diamond product advantages:
The life of cbn grinding wheel is long, 30-200 times that of ordinary grinding wheel; the dressing frequency is low, generally one dressing can continuously grind 100-200 inner circles and 500-1500 grooves; the processing accuracy is high, and the finished product rate can be improved in products with high dispersion requirements; the processing efficiency can be improved by 50%-
Compared with ordinary abrasives:
- 1. high abrasion ratio and long service life (30-200 times more than ordinary abrasives depending on the different supporting equipment and processing technology)
- 2. high efficiency, mainly processing speed can be increased, the frequency of dressing can be reduced (dressing once can grind 100-200 bearing inner circle, can grind 500-1500 grooves), the average efficiency increased by 50%-
- 3. high machining accuracy, can improve the qualification rate of high-precision products
- 4. Comprehensive cost reduction, taking into account the cost of equipment, personnel and time, the comprehensive cost can be reduced by more than 1/3
Features of diamond grinding wheels:
High processing efficiency due to the use of special high-strength, high-elasticity binding agent, and diamond, cubic boron nitride (cbn) abrasive bonding, can be adjusted with the additive elasticity, taking into account the polishing and cutting properties during processing.
It is easy to exclude the abrasive chips during the grinding process, with uniform grinding resistance, less heat generation and will not cause clogging, and has proper self-sharpening to maintain the grinding and polishing efficiency, uniform and consistent surface after grinding, beautiful surface and good finish of the processed surface.
The aluminum alloy substrate is more than 60% lighter than the iron substrate, which reduces the horsepower consumption of the machine and improves the polishing effect.
Improve the stability of processing proper grinding surface trimming and adjustment, so that the grinding wheel can be installed at the beginning to obtain stable processing efficiency.
