The bond of a CBN grinding wheel is what holds the abrasive material in place. Most vitrified wheel bonds consist mainly of naturally occurring raw materials like kaolin, feldspar and glass frits – all of which are subject to variations in quality.
the grain within the grinding wheel until the grinding process blunts the grain particle; at this point, the bond-ing should release the grain, thus pre-senting a new and sharp particle. The bonding type and the percentage of bonding used depends on the grinding application. ATLANTIC grinding wheels are manufactured in two basic bonding types:
Bond is a combined of different materials to hold the abrasives. Generally speaking, there are four main types: resin bond, vitrified bond, metal bond and electroplated bond. 1. Resin code: B.

Eagle Superabrasives, Inc. offers CBN wheels in three different bond systems: Hybrid, Resin, and Vitrified. The bond is what holds the abrasive material in place. Hybrid Bond CBN Grinding Wheels. Used in the manufacture of D2, M2, Alloy and Super Alloy End Mills, Drills, and Reamers.
27 - DEPRESSED CENTRE GRINDING WHEELS; The Type 27 grinding wheels are a very popular group of general purpose and specialized abrasive tools intended for rough grinding on various materials. They are commonly used in building, shipbuilding, metal, foundry, engineering, chemical and other industries as well as in smaller workshops ...
A Better Way to Dress Bonded Diamond Grinding Wheels Bonded diamond grinding wheels occasionally need to be trued and dressed. This may be a result of normal tool wear, or excessive grinding loads if not using optimal processing parameters (i.e. – tools speeds, and feed rates).
Jul 19, 2019· Metal bond diamond grinding wheel is mostly used for grinding automotive glass, optical glass, monocrystalline silicon,High bonding strength, good wear resistance and long service life,However, there are also disadvantages in that the wheel is …
Metal bond diamond grinding wheels are usually manufactured by powder metallurgy. The manufacturing technology includes mixing, pressing, sintering. There are 3 kinds of main production methods of metal bond diamond grinding wheel blank: cold pressed sintered, hot pressed sintered, semi-hot pressed sintered.
Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. The grinding process itself has been compared to machining operations which ...
The purpose of the bonding material is to hold the abrasive grain particles together. Vitrified Bonds Vitrified wheels have a glass bond composition. Vitrified wheels hold form extremely well and produce a high ratio of stock removal to wheel use. Vitrified wheels are commonly used for precision grinding in the tool and die market. Porosity
Apr 06, 2015· The grade of a grinding wheel refers to the hardness with which the wheel holds the abrasive grains in place. It does not refer to the hardness of the abrasive grains. The grade is indicated by a letter of the English alphabet. The term 'soft' or 'hard' refers to the resistance a bond offers to disruption of the abrasives.
A grinding wheel is a self-sharpening tool composed of discrete abrasive grains held together by a bonding agent with composite structure of many clearance allowance for the cutting edges. The characteristics of a grinding wheel depends upon the combined elements of abrasive, grit size, grade, structure and bond. GRINDING WHEEL
RESIN BOND Diamond Wheels. Resin bond is the most commonly used bond system that is used for grinding all types of Tungsten Carbide tools, Ceramics, Glass, ferrites, refractories and semi-conductors. It offers good elasticity, superior surface finish and highly efficient grinding performance at a very cost effective price. Phenolic Resins ...
A grinding wheel consists of three elements: abrasive grain, bond and pore, as shown in figure 1. As the wheel turns in high speed, its innumerable grains quickly grind workpiece to beautiful finish and precise measurement. Mechanism of grinding whetstone This process is called grinding process.
Resin wheels are made much like a traditional grinding wheel with a thick bond/grit layer usually between 1/16" and 1/4". Electroplated wheels are a much thinner thickness. In both cases, the bond layer is applied to a hub which is either aluminum or steel made to the specific profile required.
Jul 20, 2017· The amounts of each of these grinding wheel components can be adjusted as needed for a given application, and together make up a complex and functional composite intended to produce surfaces of interest. Figure 1. This schematic shows grinding wheel structure, showing abrasive grain, bond, porosity, and filler components.
Norton surface grinding wheels and segments are a universal choice for heavy, rapid stock removal and production work to precision tolerance operations. Our surface grinding wheels come in a variety of abrasive grain types and bonds and can increase grinding performance anywhere from 100-600%. See the full Surface Grinding Wheels range
Vitrified bond: Vitrified bonds are used on more than 75 percent of all grinding wheels. Vitrified bond material is comprised of finely ground clay and fluxes with which the abrasive is thoroughly mixed. The mixture of bonding agent and abrasive in the form of a wheel is then heated to …
The bond of grinding wheel is for the purpose of holding the abrasive grains of cutting edges. It is also to withstand a grinding force and rotary stress and simultaneously need characters to generate the abrasive grains adequately in accordance with the increase of grinding force by abrasive grain wear.
Jun 24, 2019· Dressing/conditioning diamond and CBN Borazon grinding wheels, resin- and metal-bond only, is one of the most overlooked processes. And most dressing is done insufficiently. The simplest and basic dressing process is to use a white aluminum oxide dressing stick. Maximum exposure is necessary to optimize the wheel performance.
Proper grinding wheel selection is essential to ensure that the required part quality, production rate, and overall cost per part is achieved. Although the type of abrasive grain is often a primary driver of wheel selection, the bonding type can also play a key role in optimizing a grinding operation.
