What You Need To Know About Diamond Grinding Wheels

Posted on by

Do you know how diamond wheels are classified?

Diamond wheels are actually classified according to shape, concentration, bond, and grit size. These wheels are used in various grinding and abrasive machining operations. Consequently, diamond grinding wheels are used in grinding machines. In any machining or grinding process, it is always important to use the appropriate grinding wheel.

 

One of the most widely used grinding wheels today is the diamond and CBN wheels. These come in several types including resin, vitrified, metal, and electro-plated. The most common among these types is the resin wheels. These are used in most tool room and production applications. On the other hand, the vitrified and metal types are newer bond types and are used in specific applications. These are rare and are more expensive. Moreover, these are usually custom made order items. However, electro-plated wheels are typically found in cut-off wheels and low demanding abrasive grinding such as that for plastics.

 

It is very important to know the different types of diamond grinding wheels and their applications because each of these types is particularly used on specific applications only. Moreover, if you are not using the appropriate wheel type, grinding operations may not be done effectively. Thus, before embarking on any grinding operations, it is essential to determine the type of material to be worked on, and the type of grinding wheel as well.

 

Diamond and CBN grinding wheels are used in a variety of processes and materials. However, diamond wheels are used strictly on carbides while CBN is used on steels. In some cases though, there are some manufacturers that produce a special grit that can be used on both carbides and steels.

 

The three types of diamond grinding wheels that are available in the market are synthetic diamond, cubic boron nitride (CBN), and alumina-zirconia. Among these three types, the synthetic diamond is the hardest, while alumina-zirconia is the softest. In selecting the particular type of wheel, there are some important factors to consider.

 

First and foremost, it is essential to determine the hardness of the item you will be grinding. You should always remember that CBN is most advisable for iron or steel. If the metal is nonferrous though, and a large amount of metal must be removed, a synthetic diamond blade is the most appropriate wheel to use. For soft metals, alumina-zirconia should be used.

 

Second, look at the nomenclature plate on the grinding apparatus. The speed rating in meters per second is very important in ensuring that the bond of the diamond grit will not separate or disintegrate when used on the grinding apparatus.

 

Third, determine if the grinding will be done wet or dry. A wet diamond grinding wheel is used for precision cutting while a dry diamond grinding wheel is used for moderate grinding purposes.

 

Finally, select the coarseness of the wheel according to the amount of metal that will be removed. A coarse grit is most appropriate for fast cutting while a fine grit is used for a finish quality cut.

Applications and Overview about Fiberglass Cloth

Posted on by

There are a variety of applications for industrial fabrics when weight, strength, and durability are important, and one common solution to these needs is fiberglass cloth. Fiberglass cloth is a strong and durable woven textile used mainly for industrial, non-apparel applications. Its unique set of valuable properties makes it ideal for many industrial uses, such as for the interiors of circuit boards and conveyor belts.

 

Fiberglass cloth is woven in various configurations from four basic weave patterns, called plain, leno, satin, and basket. It is sold in rolls that range in length from 150 feet (45 meters) to 9,000 feet (2740 meters), and in many different widths. It also offers a wide choice of controlled properties depending on the industry it will be used in.

 

Fiberglass clothes have numerous applications as thermal insulation, electrical insulation in the electronics industry, and even as a component in armor plating on U.S. Military vehicles, helmets, and aircraft carrier decks. Light-weight cloths also provide a smooth finish and are ideal for producing a waterproof layer over wood or other surfaces, such as are needed in boat repair and other marine applications.

 

Perhaps the most notable quality of fiberglass cloth itself is its high tolerance of extreme heat. It not only dissipates radiant heat with remarkable efficiency, but some types of cloth can withstand temperatures of up to 3000 degrees Fahrenheit (1648 degrees C) for as long as a minute. Another notable attribute of fiberglass fabric is its high tensile strength. At a much lower weight and cost, it has a greater tensile strength than steel wire of similar diameter. Also, fiberglass cloth is composed of inorganic materials, making it impervious to damage from sunlight, bacteria, or fungus of any kind.

 

Glass fibers are known to produce fabrics with excellent dimensional stability as well, meaning that fiberglass fabric stretches only very minimally under stress- usually about three percent or less. Like glass itself, fiberglass is highly resistant to most harsh industrial chemicals. Oddly enough, despite its resilience and resistance to almost every possible type of industrial hazard, it is important that fiberglass cloth be rolled onto a tube for shipment, and not folded, regardless of how large or small the order may be. Folding it for shipment can damage the cloth where it is creased. If this one precaution is followed, the structural integrity of the fabric will be preserved to provide strength or protection in whatever context it is needed for.
