According to the shape of the cross-section of the grinding wheel, thread grinding can be divided into two types: single-line grinding wheel and multi-line grinding wheel. The pitch accuracy of the single-line grinding wheel grinding can be 5~6, the surface roughness is R1.25~0.08 microns, and the dressing of the grinding wheel is more convenient.

Currently, the most effective way is use diamond sand belt to processing WC-Co or any other high-hardness coating.

Truing is the process of changing the shape of the grinding wheel as it becomes worn from an original shape, owing to the breaking away of the abrasive and bond. This is done to make the wheel true and concentric with the bore or to change the face contour for form grinding. While The purpose of dressing is to restore the correct cutting action of the wheel. Dressing removes the clogs on the surface of the wheel and the blunt grains of the abrasive, exposing the new sharp abrasive grains of the wheel which can be cut and brought to shape efficiently.

Dressing diamond grinding wheel can be dressed using diamond dressers, diamond roller dresser, electrochemical dressing or laser dressing, Dressing helps maintain and improve the grinding performance and wheel life.

On May 31, 2023, the 15th China International Advanced Ceramics Exhibition IACE CHINA 2023 was held as scheduled in the Shanghai World Expo Exhibition Hall. Moresuperhard brought ceramic grinding discs, vitrified diamond grinding wheels, resin diamond grinding wheels, cutting discs, internal grinding and other high-precision diamond tools to the exhibition.

Oil stones are used for grinding tools and parts, and can be installed in honing for ultra-finishing. Whetstone can be divided into man-made and natural. Most of the oilstones on the market are man-made. Some inferior whetstones have the disadvantages of poor strength and hardness, are not sharp, and are not wear-resistant, so users must choose wear-resistant whetstones when choosing whetstones. What I want to introduce to you today is the manufacturing process of artificial oil stone.

On April 10-15, 2023, the 18th China International Machine Tool Exhibition (CIMT 2023), sponsored by China Machine Tool Industry Association and co-organized with China International Exhibition Center Group Corporation, will be held in Beijing China International Exhibition Center ( Shunyi Pavilion) was held grandly.

Choose the most suitable grinding wheel bonding type. There are two commonly used grinding wheel binders, vitrified bond diamond grinding wheel and resin bond diamond grinding wheel. The grinding wheel with vitrified bond can withstand high grinding speed and precise fit tolerance, and is not affected by water, acid, oil and temperature changes, but the grinding machine speed is required to be lower than the safe operating speed of the grinding wheel, generally less than 33 m/s. Grinding wheels with resin bonds, on the other hand, can be used for higher grinding speeds and produce higher finishes.

The processing technology of monocrystalline silicon wafer is mainly as follows:

*  Cutting

*  Cylindrical grinding ingot

*  Slicing

*  Chamfering

*  Grinding/lapping

*  Corrosion, cleaning

During the grinding process, the state of the grinding wheel will directly affect the grinding result. The state of the grinding wheel includes changes in the cutting force and shape of the grinding wheel. These changes will affect the yield and reproducibility of the ground product.
