Encyclopedia > Diamond blade

A diamond blade is a circular saw blade used for cutting hard or abrasive materials. They are commonly used in the construction industry for building, remodeling and repairs. A blade is the flat part of a tool or weapon that normally has a cutting edge and/or pointed end typically made of a metal, most recently, steel intentionally used to cut, stab, slice, throw, thrust, or strike an animate or inainimate object. ... Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. ...

A red diamond blade

Diamond blades can be used for cutting concrete, brick, block, stone and other materials with similar properties. A diamond blade is composed of a steel core (unlike diamond wire) and powder metal which is combined with diamond crystals and then heated and pressed into a molding which form the diamond segments, also known as the "cutting teeth" of the blade. The diamond segments are then welded to the steel core. Image File history File links Diamond-Blades-www. ... Image File history File links Diamond-Blades-www. ...

Diamond Wire Cutting (DWC)is the process of using wire of various diameters and lengths, impregnated with diamond dust of various sizes to cut through materials. ... Powder metallurgy is a forming and fabrication technique consisting of three major processing stages. ... Molding (US) or moulding (UK) can be: moulding or molding, a decorative feature used in interior design and architecture molding or moulding, a process used in manufacturing This is a disambiguation page — a navigational aid which lists pages that might otherwise share the same title. ... Welding is a joining process that produces coalescence of materials (typically metals or thermoplastics) by heating them to welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler material. ...

The steel core can vary in design. Some of them have spaces (known as gullets) between each segment to provide cooling and slurry removal, while others have a single continuous rim for smoother chip-free cutting. The type of core that has to be used depends of the type of materials that will be cut. A slurry is in general a thick suspension of solids in a liquid and may be: Look up slurry in Wiktionary, the free dictionary. ...

How do Diamond Blades cut?

A Diamond Blade doesn't actually cut, instead it grinds. They have rectangular teeth (segments) which contain diamond crystals on the tip of each segment for grinding through very hard materials. The word grinding can mean many things: Grinding is a manufacturing process that uses friction with a rough surface to wear away or smooth the surface of a work piece - see grinding machine. ...

The bond is a term used for the softness or hardness of the powder metal being used to form the segments and hold the diamonds in place. The bond controls the rate at which the Diamond Segments wear down and allow new diamonds to become exposed at the surface to continue grinding with a "sharp" edge. The most important step is matching a blade with the right bond to your specific cutting material. Powder metallurgy is a forming and fabrication technique consisting of three major processing stages. ... This article is about the gemstone. ...

Selecting the correct diamond blade

First thing you should know is how hard, or abrasive, the material you wish to cut is. Each Diamond Blade is unique in its combination of: bond, diamond concentration, diamond sizes/shapes, width, segment design, core design, etc. Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. ... In chemistry, concentration is the measure of how much of a given substance there is mixed with another substance. ...

To get the most efficient cutting you should always try to match the type of blade to the specific material it's designed to cut.

Cutting with or without water

Diamond tools and blades require wet cutting. The water will prevent the blade from overheating, greatly reduce the amount of harmful dust created by cutting, and will remove the slurry from the cut. Diamond cannot withstand the forces involved at the elevated temperatures of dry cutting ceramic and abrasive materials, and will be subject to rapid tool wear and possible failure.

When water cannot be used (electrical saws for example), measures should be taken so the operator does not inhale dust created by the process, which poses a very serious health risk. When doing dry cutting, the blade should be allowed to cool off periodically. Cooling can be increased by allowing the blade to spin freely out of the cut. This allows cool air to pass between the segments. Dry diamond cutting is dangerous for persons unfamiliar with the risks and process.

  • Always take safety precautions when using any type of power tools: Wear safety equipment. High levels of dust or improper usage of diamond blades can be harmful.
