Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.
The Basics: Diamond Sintered Bond - Diamond Productions
The Process. Like all diamond tools, diamond grit is suspended or held within a matrix. In the case of the sintered bond, the matrix is comprised of varying metal powders subjected to high heat and high pressure fusing the matrix and diamond grit into a solid metal segment. The resulting piece is a multi-layered segment designed to grind.

Grinding Precision and Productivity Reach New Heights
Grinding, like all machining processes, is generally thought of as a process of tradeoffs. To gain one attribute, you have to sace another. However, that is not always true. For example, one logical attempt to achieve good material removal rates as well as limited wheel wear is to fix diamond or CBN super-abrasives in a sintered metal bond.

Define Lapping: The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.
Sintered Carbide - an overview | ScienceDirect Topics
Cemented (or sintered) carbides, known collectively in most parts of the world as hard metals, are a range of very hard, refractory, wear-resistant alloys made by powder metallurgy techniques. The minute carbide or nitride particles are cemented by a binder metal that is liquid at the sintering temperature.
What Is Powder Metal Manufacturing? | L&L Special Furnace Co.
Powder metal (PM) parts are created from a very fine metal powder that is compressed and sintered to achieve its final shape. This is quite different from cast parts, which begin their life as a liquefied metal, or from machine or forged parts, which start off as stock metal. The powder metal manufacturing process makes it possible to create ...

Sintering Process. The aim of the MEBIOS process is the formation of a ventilation route in the sintering bed by creating a low-density area around the large pellets arising from a kind of wall effect and suppression of sinter bed shrinkage due to support of the load by the dense large pellets in the upper part of the sinter bed.
Metal Powder Manufacturing | Modern Techniques
3. Atomisation Processes. Atomisation is the breakup of a liquid into a fine spray. If done on a molten material, the resulting spray commonly freezes into powder. There are many ways to atomise metal ( 8 ), but for the modern manufacturing methods discussed here, the only processes widely used are water and gas atomisation.

Dressing And Trueing | NORITAKE CO.,LIMITED
Dressing. When the sharpness of grinding wheel becomes dull because of glazing and loading, dulled grains and chips are removed (crushed or fallen) with a proper dressing tool to make sharp cutting edges and simultaneously, make recesses for chips by properly extruding to grain cutting edges. Thus, these operations are for the dressing. Trueing.
