Grinding and Polishing Introduction
The following is the introduction to Grinding and Polishing. Grinding and polishing involve a step-by-step reduction of the roughness of a surface to access the undeformed structure. Grinding uses fixed abrasives—the abrasives particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on cloth; the abrasives particles are suspended in a lubricant and can roll or slide across the cloth and specimen. This process is based on using abrasives particles in progressively finer grain sizes. In materialographic grinding, these abrasives are bonded in resin or metal matrix, with the most frequently used grinding abrasives being silicon carbide particles. These particles are often used when working with softer, medium or hard materials, composites and electronics. It is also possible to utilize diamond particles for harder components like ceramics, carbides, glass or stone. Welcome to contact us to exchange what is Grinding and Polishing meaning? and look forward to your information.
Can i get sample in free , how long is the time?
Yes, certainly. We will provide the sample is in free below 5 kgs for free, and the freight cost for free in 1kg. We could arrange the existing samples express delivery immediately. For any special samples requirement, it need max 7 days finished. Usually we send samples by TNT ,FEDEX,
Can you customized quality, size, package according to customer?
Yes, of course. The OEM is available. We will do the creation in your requirement and make ur image come true.
What is the refractive index of white fused alumina compared with that of glass?
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
Can customer ask for the third party certification?
Yes, No problem, but Customer resposiable for the charge.
What is the difference between aluminium oxide and white fused alumina?
Al2O3 alumina is the starting material of aluminium production, both of metallic aluminium and aluminium oxide. It is porous an has a large reactive surface.
What is the warranty policy?
Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.
What is the shelf life of fused aluminum oxide?
fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely
Sample cost is refundable or not?
Yes, Sample cost below 5 kgs can be refunded when bulk order confirmed,But freight cost for more than 1kg don’t be refunded.
What is a mesh vs. Grit size?
If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through, then that sieve would be called a 10 mesh sieve. Typical sieve
Type of glue required:
This decision is made by the type of abrasive you have selected or the type of process you will be performing. Glue – A straight animal hide glue that is used to adhere the abrasive particles to the backing. Referred to as “Glue Bond”. Resin – A synthetic resin that
Coarseness of the abrasive mineral:
Commonly referred to as “grit”, this number designation is determined by the amount of abrasive mineral that can pass through a mesh screen with specific size openings. Therefore, a 40 grit abrasive particle will pass through a mesh screen that has 40 openings in one linear inch. Consequently, the higher
