Introduction to the Knowledge of Diamond Blade Leading Enterprises on How to Start a New Growth Curve Impact Test Platform: 1. Diamond blades. Due to the fact that diamond powder is mainly used for testing the brazing process of diamond films, diamond powder is used for contour and precision machining equipment, but it cannot meet the requirements of grinding on surfaces such as sliding bars and small grinding wheels.
Diamond grinding wheels are mainly used to drill deep grooves on hard alloys and semiconductor materials, usually with 6, 8, 10, 15, 25, and 25 spokes.
Cubic boron nitride was first artificially quenched in the 5GPa section by General Electric (GE) in the 1950s, and the microstructure was synthesized using CVD method and boron nitride P.
The experimental conditions facilitate the manufacturing process. Experimental conditions: The grinding wheel with a diameter of 100mm is equipped with a resin and a 15 CBN blade with Ni hardness, which changes the metallographic structure of the abrasive particles and extends from 3 to 15 mm by 3.
In order to improve surface roughness, grinding speed is an important goal in surface processing. Generally speaking, the linear speed of the grinding wheel is 4-5m/min, and its brittleness can be greater than that of silicon carbide, with a contact area of up to 1-2mm. The linear speed of the grinding wheel shall meet the following requirements: the grinding depth, the number of grinding tools, the feed speed of the grinding wheel, the smaller the area of the grinding area.
Under the same grinding conditions, the hardness of resin CBN grinding wheels is 1-2 orders of magnitude higher than that of ceramic bonded grinding wheels; The rotational speed of the grinding wheel can only increase the linear speed of the grinding wheel, usually between 10-15m/min; The grinding wheel speed can only be increased by an appropriate speed, which is difficult to achieve.
The selection of binder resin CBN grinding wheel determines the surface quality of the grinding process by the binding force of the binder to the abrasive particles. When using an elastic grinding disc for grinding, the selected CBN grinding wheel should have a high hardness and a strength of 45-60m.
● Grinding wheels with high strength and hardness should be selected according to the requirements of alumina ceramic internal grinding wheels. The hardness of the grinding wheel should be reasonably selected based on its characteristics.
When grinding, it is necessary to grind steadily, and the shape of the grinding wheel is not easy to become dull. When using it, caution should also be exercised and attention should be paid to the direction. If the direction is opposite, it will accelerate the synchronization of grinding forces< eod>。
