How To Choose Metallographic Sandpaper And Diamond Grinding Disc For Rough Grinding?

Image
In the big family of metallographic consumables, there are many consumables with the same functions and consumables, such as metallographic sandpaper and diamond grinding discs . These two consumables are used for rough grinding of samples. These two functions are the same, so how to choose? In the preparation of metallographic samples, in addition to cutting and inlaying, the most critical step is probably the grinding and polishing process. In the case that the cutting does not produce deep, irremovable defects, the mosaic is also reasonable, so the key is to grasp the grinding and polishing process. In the case of skilled sample preparation, the quality of sample preparation depends on whether the consumables selected for each grinding and polishing process are appropriate. As metallographic sandpaper and diamond grinding disc are both used for rough grinding process, there are still differences in application between the two. If you understand these differences, you can choose t

How To Polish Marble?

Before polishing the marble, it should be glued according to the material. After the gluing treatment is completed, grinding and polishing are carried out. A single line drawing should be roughly ground, and 0.5mm of fine grinding and water grinding allowance should be left during rough grinding. The lines are spliced according to the installation drawing, and the color of the line surface is selected and assigned to ensure the good effect of color and pattern. After water grinding 500 lines, firstly number them according to the requirements of the installation drawing, and then disassemble and grind. This will not cause the polishing and polishing lines to be uneven at the interface; when the interface is misaligned, the grinding of the transition section should be extended, the longer the better and use a ruler to check the straightness when grinding; when polishing marble, carefully check the grinding and polishing of the smooth surface of each abrasive or grinding disc after grind

Applications Of Ceramic Bond Diamond Abrasive Tools

Ceramic bond diamond abrasive tools have excellent performance. They have the characteristics of high hardness, high wear resistance, high thermal conductivity and sharp abrasive grains, etc. The characteristics such as heat resistance, water resistance, oil resistance, acid and alkali resistance make them not only have stronger grinding ability than ordinary abrasive grains, but also have less wear and longer service life, and can withstand grinding higher temperature, and at the same time has higher grinding accuracy. They can maintain a good shape for a long time and in addition, the ceramic bond diamond abrasive tools also have more pores, which can facilitate cooling and chip removal, and it is not easy to block and burn the workpiece during grinding. The ceramic bond diamond abrasive tools have good self-sharpening, long dressing interval, easy dressing and low maintenance cost. It is precisely because of the excellent performance of ceramic bond diamond abrasive tools, they have

Grinding During The Use Of Concrete Curing Agent Is Also Important

Image
Some people will ask when using concrete curing agent: Can I use the curing agent without grinding and just apply the material? The answer is: Grinding is still necessary. If the ground is uneven, loose, etc., the ground will be smoother after grinding, and the gloss of the ground will be better. The grinding after the curing agent material is also used to make the material to penetrate into the ground better, so that the curing effect is better. To grind the concrete floor better, premium grinding tools are crucial. TransGrind Tools manufacture aggressive and effective diamond grinding tools for you, make your concrete grinding process easier. Ground grinding is the basis for the use of curing agent to have a good effect. The best step in the construction of concrete sealing curing agent is to polish the concrete base surface. Grinding is an important factor in determining the quality of the floor project. The purpose is to open the capillary pores of the concrete and make the con

What Is Polished Concrete?

Image
Polished concrete refers to the concrete surface formed after the concrete is gradually polished by abrasive tools and combined with chemical hardeners. Constructors use chemical hardeners to penetrate the naturally poured concrete to strengthen its surface strength and density, and improve its flatness and reflectivity through mechanical grinding and polishing, so that the concrete floor has both performance and special decorative effects and it is suitable for commercial floors, such as restaurants, cafes, specialty stores, schools, shopping malls, upscale-offices private garages, etc.   Advantages Of Polished Concrete Floors: 1. Hardness: the Mohs hardness of the ground treated with concrete sealing and curing agent will reach 9, and the Mohs hardness will increase by 45.3%; 2. Wear resistance: The concrete sealing and curing agent can solidify various components in the terrazzo into a hard entity to increase the hardness and compactness. After the ground is cured with the ter

Grinding Features

Image
Grinding is a method of cutting a workpiece with a grinding wheel as a cutting tool on a grinding machine. The features of this method are: (1) Since the abrasive grains of the grinding wheel have high hardness and heat resistance, grinding can process materials with high hardness, such as hardened steel and cemented carbide. (2) The characteristics of the grinding wheel and the grinding machine determine that the grinding process system can perform uniform micro-cutting, generally ap=0.001 ~ 0.005mm; the grinding speed is very high, generally up to v=30 ~ 50m/s; the grinding machine has good rigidity; using hydraulic transmission, so grinding can economically obtain high machining accuracy (IT6 ~ IT5) and small surface roughness (Ra = 0.8 ~ 0.2μm). Grinding is one of the main methods of finishing parts. TransGrindTools manufacture wide range kinds of diamond grinding tools which can make your grinding work easier and more effective. ​​ (3) The temperature of the grinding zone

Refinement Management Of Concrete Pouring

Concrete engineering is one of the main construction tasks in engineering construction, and the molding quality largely determines the final appearance of building products. The construction cost of concrete engineering accounts for about 20%-30% of the total project cost, which is the focus of the cost management of the construction unit. Concrete construction management is one of the main ways to improve project quality and reduce construction cost. Concrete pouring is one of the main construction tasks in construction projects, which usually includes foundation concrete pouring, structural concrete pouring, and secondary structure and sporadic component concrete pouring. Concrete pouring construction generally includes the main contents of concrete mixing and transportation, concrete pouring, vibrating, curing and quality defect repair. Due to the limitation of construction technology, concrete construction usually has to be poured continuously, so nighttime construction is often
