The Diamond dicing blade is mounted on the soft blade flange of the cutting equipment’s spindle. Under high-speed rotation of the spindle at RPM 20,000 to 30,000, the workpiece to be cut are broken by fracturing way and the chip pocket to remove the chips in time to ensure the processing quality.

The forum will have the invited oral presentations from the engineering practitioners, leading researchers, industrialists and academics, and in parallel the industrial exhibitions from leading companies in the field. Both of them will try to show off the best practices, innovation ideas, products and services. Furthermore, there will be industrial round table discussions, demos and meetings with Venture Capitals in precision engineering and the companies’ tour.

With the continuous progress of electronic information, the semiconductor industry is also changing with each passing day. In order to meet the market demand, the manufacturing process of all kinds of electronic control components is also developing towards the direction of small volume, excellent performance and low energy consumption. Such as IC packaging DFN, QFN, BGA and other process types.

The purpose of grinding as the finishing step is to obtain the surface quality which cannot be achieved by hard machining. Shaft products require high surface quality of bearing mounting position or sealing position. For example, some surfaces require a non-helical surface, which is not possible with hard cars. Some parts are severely discontinuous, and turning can be a quick way to remove the margin. The precision grinding process is then used in the same clamping process in order to precisely grind to the required size and surface quality. Because the margin of grinding after hard lathe machining is very small, the grinding wheel wears lightly, which can reduce the dressing times and improve the processing efficienc

Pre grinding, the cutting force will be very high, so the shorter grinding time is better.

The “DMP Greater Bay Area Industrial Expo” will be held in Shenzhen International Convention and Exhibition Center (New Pavilion) from November 24 to 27, 2020, with an estimated scale of 320,000 square meters.

Single-point cone tool –  A single-stone diamond is embedded in one shank. This tool is good for complicated forms and radius dressing. As the diamond wears, a flat will develop, resulting in a dull grinding wheel. As a result, frequent rotation of the diamond tool is required.

With the development of economy and the progress of science and technology, different industries have basically the same requirements for electroplated diamond tools, that is, high efficiency, long life, and high grinding precision. To ensure these characteristics, the coated metal must not only have higher hardness and wear resistance, but also must be evenly distributed in all parts of the substrate to prevent the coating from falling off and shorten the tool life. In some special industries, such as powerful grinding in the magnetic material industry, the feed rate is controlled at about 0.3mm.

Recently, we have a customer met a problem in his grinding work. He is using our resin bond diamond grinding wheel for this carbide workpiece grinding. The wheel works very good in the beginning, but later, he finds the wheel is blocked by the chippings. Grinding wheel losses grinding ability, becomes dull and grinding efficiency reduced very much. Under this circumstance, he asks me for help. This is a common issue during grinding work, not a big problem, and very easy to control.

The inner hole of high speed steel hob will be deformed after carburizing heat treatment. The unilateral deformation will range from 0.1 mm to 0.25 mm, and the surface hardness can reach above HRC60 degrees.
