Classifications & Attributions Of Bonded Abrasives

 

Bonded Abrasives are a kind of tools that are made by abrasive grains and bonding agent, with a certain shape and grinding ability. Usually, according to different abrasive grains, they are divided into ordinary bonded abrasives which are made by conventional abrasives (Aluminium Oxide, Silicon Carbide) and superhard bonded abrasives which are made by superhard abrasives (Diamond, cBN); or, according to different bonding agent, they are divided into vitrified bond, resin bond, rubber bond, metal bond, etc. Based on actual situation, in iAbrasive.com (www.iabrasive.com), they are included in the category ofBonded Abrasives, made by conventional abrasive grains, and there is no metal bond type to choose from. Suparhard bonded abrasives are included in another independent main category of iAbrasive.com, namely Super Abrasives.

As shown in Figure 1, Bonded Abrasives is sub-classified into 7 further levels in iAbrasive.com. It’s not hard to see that, iAbrasive.com takes shape as the criterion; it is also in conformity with the principle of intuitive and universal. Cut-off & Grinding Wheels is further classified into two more levels within these by shape and application; the same goes for Mounted Points, also with two further levels.

Ⅰ. Grinding Wheels

There is a great variety of grinding wheels, but here, no further sub-categories within them, why? Because in the industry, there are different opinions about it, some classify them by model, some by bonding agent, and some by application. So, iAbrasive.com complies with the principle that when users add products they can identify their unique products by different attributes illustrated as following.

The mains characteristics of grinding wheels are determined by abrasive grains, grit size, bonding agent, hardness, structure, shape, diameter, etc., so iAbrasive.com set following attribute fields for grinding wheels:

Shape: Straight, Cylinder, Tapered, Recessed, Straight Cup, Flaring Cup, Dish, Relieved, Disc / Ring, Other
Diameter: Common diameters 10mm-1200mm are available to choose from;
Application: Cylindrical/ Centerless, Internal/ Bores, Surface/ Creepfeed, Toolroom/ Sharpening, Cutting-off, Snagging, Polishing, Specialty
Abrasive Grain: Aluminum Oxide, White Aluminum Oxide, Silicon Carbide, Zirconia Alumina, Ceramic Aluminum Oxide, Boron Carbide, Natural Abrasives, Combination, Other
Grits: 16-220
Bonding Agent: Vitrified, Resin, Resin Reinforced, Rubber, Rubber Reinforced, Magnesite, Shellac, Plastic, PVA, Other
Hardness: Soft, Medium, Hard
Structure: Dense, Open
Work Condition: Dry, Wet, Dry/ Wet

Seen from above attributes, it’s not hard to see that, Shape does not cover all existing values, only the most commonly used shapes are listed, neither for Diameter which does not contain the value over 1200mm, these will be further adjusted according to data; ForHardness and Structure, the reason for not being marked by letters or numbers is that, there is not a universally accepted standard for each country, so here they are indicated by words for rough screening.

Ⅱ. Cut-off & Grinding Wheels

Cut-off & Grinding Wheels are the most consumable products within bonded abrasives, and they appear as one main category independently in many product catalogues and websites. Based on actual situation, and in order to avoid misunderstanding, iAbrasive.com classifies them under Bonded Abrasives. Because the quantity is so huge, iAbrasive.com further classifies them into Straight Cutting Wheels and Depressed Center Wheels, their attributes have both similarities and differences, details of which are as following:

Diameter: Common diameters 10mm-1200mm are available to choose from;
Abrasive Grain: Aluminum Oxide, White Aluminum Oxide, Silicon Carbide, Zirconia Alumina, Ceramic Aluminum Oxide, Combination, Other
Grits: 24-120 are available to choose from
Style: High Speed, Chop Saw, Portable Saw, Stationary, Thin(<2mm), Circular Saw, Street Saw, Gas Saw, For Rail
Materials Abraded: Aluminum, Brass/ Bronze, Cast Iron, Cast Steel, Ceramic, Chrome, Gray Casting, Glass, Nickel Alloy, Plastics, Steel/ Steel Alloys, Stainless, Stone/ Masonry, Titanium, Universal, Other
Type: Grinding Wheels, Cutting-off Wheels, Combo

Style is specially set for Straight Cutting Wheels, and it is a multiple choice, users can select according to their products features. Type is specially set for Depressed Center Wheels, because there are grinding wheels, cut-off wheels, as well combo wheels for both grinding and cutting-off, all in depressed center shape. Materials Abraded is also a multiple choice, iAbrasive.com does not suggest selecting all values, while if the supplier does think all the listed materials are applicable, Universal can be selected. Selecting the most appropriate one or several materials abraded may improve product visibility; on the contrary, selecting all values for one product may result in lower ranking in screening, decreasing product visibility, and leaving a dishonesty impression to buyers.

Ⅲ.Mounted Points

Mounted Points can be introduced individually, but in the actual supply and demand, they usually appear in sets. So, iAbrasive.com further classifies Mounted Points into Mounted Points and Mounted Point Set. The attributes and values are described as following by iAbrasive.com: 

Shape: Ball, Cone, Cone-Ball Nosed, Countersink 60° 60, Cylinder, Cylinder-Ball nosed, Inverted Cone, Other
Head Diameter: 1.5mm-75mm are available to choose from
Shank Diameter: 2.5mm-10mm available to choose from
Abrasive Grain: Aluminum Oxide, White Aluminum Oxide, Silicon Carbide, Zirconia Alumina, Ceramic Aluminum Oxide, Combination, Other
Grits: 16-220 are available to choose from
Bonding Agent: Vitrified, Resin, Rubber, Shellac, Plastic, PVA, Other
Hardness: Soft, Medium, Hard
Number of Piece8-100 are available to choose from

There are various mounted points, such as vitrified ones, rubber ones, etc. and suppliers may select by different abrasive grains and bonding agent; There is also a great many of shapes for mounted points, but no uniform symbols for each company, so iAbrasive only list the most popular shapes for selecting. Number of Piece is specially set for Mounted Point Set, with the most popular piece numbers for selecting.

Hone/ Sharpening Stone

Hone/ sharpening stones are strip-shaped boned abrasives made by abrasive grains and bonding agent. During the machining process, they usually need lubricating oils. They are generally used for manual sharpening for cutting tools & accessories, or clamped on machine tools for honing or super-finishing. Hone/ sharpening stones are either natural or synthetic, with various shapes. iAbrasive.com does not make further classification within them, still, using following attributes for differentiating:

Type: Abrasive File, Bench Stone, Water Stone, Honing Stick, Rubbing Brick, Slip/Slip Stone, Specialty
Shape: Rectangular, Square, Round, Half Round, Triangle, Wedge, Specialty
Dimension: Customized
Abrasive Grain: Aluminum Oxide, Boron Carbide, White Aluminum Oxide, Silicon Carbide, Zirconia Alumina, Ceramic Aluminum Oxide, Arkansas Stone, India Stone, Combination, Other
Bonding Agent: None, Vitrified, Resin, Rubber, Other
Coarseness: Coarse /Metal Removal, Medium/ Deburring, Fine /Stoning, Extra Fine/ Superfinishing, Combination Grits
Application: Internal /Bores, Flat Surfaces, Shafts/ Connecting Rods, Wheel Dresser/ Dressing Tool, Specialty

It’s worth mentioning that grit size is not easy to confirm, so here this field and value don’t appear, while replaced by Coarseness. There are other more applications besides above mentioned ones, which are only industrial applications but still not complete, we will further adjust according to data and buyers buying situations.

Ⅴ. Grinding Segments 

Grinding Segments are blocky bonded abrasives make by abrasive grains and bonding agent. The majority is made by aluminum oxide or silicon carbide and resin; also some are made by ceramic aluminum oxide and magnesite. Usually, several segments are fixed on the chuck of a grinding wheel as an assembly; there is a certain distance between each segment for easy thermal dissipation and chip removal. iAbrasive.com tries to satisfy all suppliers’ posted products as possible as we can, collecting current existing bonding agents and abrasive grains as the attributes and values, details of which are as following:

Shape: 3101, 3102, 310, 3104, 3105, 3109, Specialty
Dimension: Customized
Abrasive Grain: Aluminum Oxide, Boron Carbide, White Aluminum Oxide, Silicon Carbide, Zirconia Alumina, Ceramic Aluminum Oxide, Combination, Other
Bonding Agent: Vitrified, Resin, Magnesite, Other

The Shape symbols here are only applicable on iAbrasive.com. When posting products, suppliers can click to select by skeleton diagram.

Ⅵ. Cones & Plugs 

Compared with mounted points, Cones & Plugs don’t have handles. As a kind of bonded abrasives, they do exist in many products catalogue and websites in many countries, although the quantity is much smaller inChina. iAbrasive.com also show them up as one sub-category here.

Shape: Round, Taper, Square, Cylindrical, Other
Diameter: 25mm-70mm is available to choose from
Grit: 16, 20, 24, Other

Ⅶ. Other Bonded Abrasives

Simply selecting this category without careful thinking is strongly discouraged by iAbrasive.com, unless you do ensure that your product is ordinary bonded abrasive but above mentioned six categories all do not match, because products in this category will show in the bottom of this category listing.
