Product types and uses
The grinding paste is divided into two types: water-soluble and oil-soluble, of which:
Oil solubility: mainly used for composite mechanical grinding, polishing hard alloy, alloy steel, high carbon steel and other hard materials. Suitable for various rusty workpieces.
Water-soluble: It is mainly used for the refining of metallographic and petrographic samples. (CBN grinding paste is extracted from water, so it is not suitable to use water-soluble grinding paste. Oil solubility is usually selected.)
Diamond / CBN (cubic boron nitride) grinding paste is finely formulated with diamond / CBN (cubic boron nitride) fine powder and other raw materials. It has good lubricating and cooling properties and is ideal for grinding and polishing. Diamond paste, and diamond / CBN (cubic boron nitride) has high particle hardness and uniform particle size.
This product is suitable for the processing of measuring tools, cutting tools, optical instruments and other high-quality workpieces made of high-hardness materials such as glass, ceramics, hard alloys, natural diamonds, and gemstones.
Selection of diamond / CBN (cubic boron nitride) abrasive paste
The choice of diamond / CBN (cubic boron nitride) grinding paste is mainly determined according to the requirements of the workpiece's finish and processing efficiency and the original finish of the workpiece. If the allowance is large and requires high processing efficiency, a coarser grain size number can be selected; if the allowance is small and high finish is required, a finer particle size can be selected.
Five, the use of diamond / CBN (cubic boron nitride) abrasive paste and precautions
• Select the appropriate grinding device and paste according to the material and processing requirements of the workpiece. Commonly used grinders are blocks and plates made of glass, cast iron, steel, aluminum, plexiglass and other materials. The abrasive paste is shaped like a toothpaste, so it cannot be used alone. It must be diluted with a diluent. Water-soluble abrasive pastes are generally diluted with water or glycerin, and oil-soluble abrasive pastes are diluted with kerosene.
• When using, squeeze a small amount of grinding paste into a container or directly on the grinding device, and dilute it with a diluent. The ratio of the two is generally 1: 1, and it can also be adjusted according to the site usage. Glycerin is added to the water as the particle size increases.
• During the processing process, the workpiece must be carefully cleaned before changing to different size abrasive pastes, so as to prevent the coarse particles of the previous process from mixing into the fine-grained abrasive paste to scratch the workpiece.
• After grinding, the workpiece should be cleaned with gasoline, kerosene or water.
