Types of Electroplated Diamond Tools
Electroplated polishing pads is one of the abrasive tools. It uses a certain bonding agent to bond the abrasive together. It is generally installed on grinders, grinders, polishing machines, or special installation tools, etc. It is widely used in optical lenses, prisms, Watch glass, sapphire glass. Through the processing of various workpieces, the effect of grinding, grinding and polishing can be achieved; according to the use, it is mainly divided into the following types of abrasive tools:
1. Grinding: Mainly installed on the grinding head of the grinding machine, grinding the workpiece such as internal cylindrical grinding and external cylindrical grinding. Grinding can be divided into rough grinding and fine grinding during processing.
2. Grinding: Generally used for grinding the burr of the workpiece, or processing the surface of the workpiece with low precision. Use grinding machine, electric, pneumatic and other tools to run at high speed to achieve the grinding effect.
3. Polishing; it is specially used for processing that requires higher surface finish (roughness), and it is a process that requires separate processing.
Application of Electroplated Diamond Abrasives
Electroplated diamond abrasive tools: Due to the high hardness of diamond itself. It is divided into man-made and natural, among them, the natural hardness is higher, but it is expensive because of its rarity. As a result, the most used synthetic diamond abrasive products on the market are the majority.
Therefore, diamond abrasive tools are also widely used. There are many varieties and specifications of diamond abrasive tools according to national standards, especially in the size and shape of the abrasive tools. These are determined according to the use of diamond abrasive tools. For example, the grinding head is very prominent when grinding inner holes. At the same time, it is also a good helper for ordinary abrasive tools, especially when it is used for hard-to-grind materials.
Because diamond abrasive tools are mainly made of diamond abrasives, they are combined with resin, metal, ceramics and other binders. At this point, the use of diamond abrasive tools is more special. It is indispensable for grinding inner holes and other places where grinding wheels cannot be ground. It is mainly used for grinding, polishing and grinding. At the same time, according to the above characteristics of diamond, it can be divided into the use of grinding high and hard alloy and non-metallic materials according to the material.
In this regard, the use of diamond abrasives is unique compared with ordinary grinding wheels. It has high hardness, high compressive strength and good wear resistance. In grinding, diamond abrasives become hard and brittle materials and hard materials. It is the most ideal tool for grinding workpieces. It not only has high efficiency and high precision, but also has good roughness, low grinding wheel consumption, long service life and improved working conditions.
Therefore, the use of diamond abrasive tools is becoming more and more obvious. It is widely used in metal and non-metallic hard and brittle materials with low iron content that are difficult to process with ordinary grinding wheels, such as cemented carbide, agate gemstones, high-alumina porcelain, and optical glass. , semiconductor materials, stone, etc. In the grinding industry, the selected abrasive bonding properties are not the same due to the different materials being processed.
Electroplating abrasives are one of them. They are made of diamond or CBN abrasives, which play an important role in grinding hard-to-grind materials, materials with high precision requirements, and super-hard materials. Production methods are now more and more technically specialized. Electroplating diamond abrasives have different results due to the level of material, so the role of electroplating abrasives in production is to choose different particle sizes according to different applications and requirements. The following are normal particle sizes: 80#, 100#, 120#, 150#, 180#, 220#, 320#, 400#,
600#, 800#, 1000#, 1200#, 1500#, 2000#, etc.
Which is wear-resistant, electroplated diamond abrasive tool or sintered diamond abrasive tool?
Generally speaking, electroplated diamond abrasives are not as wear-resistant as sintered ones, because electroplated ones generally have only one layer of abrasive grains, while sintered ones can have multiple layers. However, the geological drill bit made by the electroplating process can be coated with multiple layers of diamond, which has high wear resistance. Both techniques have their own advantages and uses. For small, precise grinding tools must be made by electroplating process. The electroplated diamond process also has many advantages: low operating temperature, simple equipment, low investment, precision special-shaped products can be produced, easy to rework and recover diamond, and so on.
