What is Grinding? - Definition from Corrosionpedia

Grinding is a method of reducing the size of hard materials or sharpening tools, generally accomplished in several stages. To produce desired fineness of end products, grinding is done after crushing. For example, through crushing the mineral ore to below a certain size and finishing by grinding it into powder, the ultimate fineness depends on ...

What is Electrochemical Grinding and How it's done ...

Hard materials pose a difficulty to other types of machining due to the tool wear that is associated with machining hard materials. It may come as a bit of a surprise that electrochemical grinding can remove material from a hard surface and experience minimal wear. Because most material is removed through electrochemical reactions, the ...

Grinding the Hard Stuff - SME

To grind hard materials, such as ceramics or carbide, it's essential to have a stiff machine. This allows the use of "hard" wheels and precise truing and dressing. The results are good surface finish and quality part size and geometry. "For someone just starting this type of work, the main issue is understanding the entire process.

[Solved] Grinding of hard materials requires

Soft wheels lose grains readily, whereas hard wheels retain their abrasive grains. Soft wheels are generally used for applications requiring low material removal rates and grinding of hard work materials. Hard wheels are typically used to achieve high stock removal rates and for grinding of relative soft work materials.

Hard Metals - NETZSCH Grinding & Dispersing

Hard metals are used extensively for mounting tools and parts for machining, chipless profiling and abradant attrition. Considered as composite materials, this materials group is characterized by its metallic nature and the particular combination of the properties hardness and toughness. As a general rule, hard metals are made up of 90 - 94% ...
