Less heat of the diamond will be generated through the holes in the grinding process. This can reduce or avoid burns and cracking on the surface of the workpiece and reduce wear and energy consumption of the equipment. The size change of diamond grinding tools is very small. This may lead to good grinding quality and high grinding accuracy. Long life, long dressing period, which can greatly improve work efficiency, improve the working environment of workers, and reduce the labor intensity of products. The processing cost of each workpiece is low.
Diamond dressing is brazed to a steel handle by a single point or multi-point tool, and is used for shaping and grinding wheel dressing. There are several types of these tools, including: Gravel impregnation, crown type, PCBN integral blade and disc type. The advantages of point to multipoint tools passing through a single point are: 1. The whole diamond can be used; In the single point tool, when the point is blunt, the diamond must be reset, and the diamond replaces a few reset rings. 2. Point to multipoint tools have higher accuracy, especially in form grinding, where blade types are used. The blade comprises an elongated diamond. The thickness control and the blade can be in a thickness of from 0.75 to 1.40 mm (0.030 to 0.055 inches). 3. The gravel type tool is a difficult grade and can be used for bench grinder. Due to the use of small points, diamonds are at the forefront of natural percentage points, unlike single point tools, which have subdivision points. Multipoint tools are less expensive because they use smaller, cheaper diamonds.
Polycrystalline diamond tools are widely used in automotive, aerospace and other industries. They are ideal for high-speed machining (9000 surface feet per minute or higher) of tough and abrasive aluminum alloys, and high wear processes such as carbon fiber drilling and ceramics. The cut corners of the diamond make it last for a long time and need to be replaced. High capacity process, strict tolerance and strong grinding process are ideal diamond tools.
