What is grinding cup wheel
A grinding cup wheel or a diamond cup wheel is a metal bonded metal diamond tool packed with diamond segments that are welded after cold pressed on a steel wheel body and on the other metals such aluminum which generally represents that of a cup. In manufacturing, the removal of metal by a rotating abrasive wheel is similar to a milling cutter. The cutting wheel is composed of many small grains bonded together, each one acting as a miniature cutting point.
 
A grinding wheel cup is very important equipment used in the concrete building materials that generally are used to perform good finish on the surfaces. The Cup grinding wheel is suitable for the grinding of chilled steel, cutting tools and workpieces of alloy steel as well as the precision grinding of measuring tools and parts of instruments and apparatus, etc.
 
 
What is the importance of grinding cup wheel?
 
Grinding wheels come in various shapes, like a cup, dish, and cylinder. The shape of the wheel changes every time with its use. When you notice that the wheel's shape is completely different from that which was initially displayed. A cup wheel is predominantly used in Tool and Cutter grinders where the orientation of the wheel and a slim profile are required. These wheels are used on the side face and have the advantage of producing a truly flat surface on the side of lathe tools. They are used in jig grinders so to produce flat surfaces or counterbores. Grinding wheel tools are an extremely hard and efficient option. They are best known for their sparkle and elegance, but they also have a durable quality which makes them ideal for dressing tools.
 
 
Various uses of the grinding cup wheel
 
The various style and specifications of the cup wheels are designed on the basis of the various requirements and its applications. One thing that has to be understood is that the big segments can take up the various workloads. For instance, for the grinding of concrete and stone can be done with the big segments and the small and sparse diamond segments are normally used for the removal of paints, wallpapers, glues, epoxy, and other surface coatings requirement.
 
The diamond segments on the diamond grinding cup wheels can exist in different bonds, varied diamond grits along with the different diamond quality and different diamond concentrations that will entail the various uses of the diamond cup wheel. For instance, the bond has to be softer in cases when the material ground is hard and if the material is soft and the bond development should be harder.
 
 
Component of grinding wheel
 
The abrasive grain is the element that actually performs the cutting activity in the grinding process.

The role of the bond is to hold the individual grains together. Bond depends on the operating speed of the wheel, type of operation and the surface finish required.

The pore is the exist between grains and bond. In order to provide chip clearance, air space must exist between grain and bond. Dense spacing is denoted by low numbers and open spacing by high numbers.

 
Functions of grinding wheel
 
Removal of stock
Generation of curved, cylindrical and flat surface
Production of highly finished surfaces
Cutting off operations
Production of sharp edges and points.
 
 
The manufacturing process of the diamond grinding cup wheel
 
There are generally two methods of manufacturing diamond grinding cup wheels, one is the hot-pressing method and the other is the cold pressing method. In the hot-pressing method, the diamond segments are put in the molds under pressure through sintering press machine. In the cold pressing, the method is to fit the press the working layer that contains the diamonds and then form the grinding wheel’s body.
 
 
Choosing the right grinding wheel
 
The grinding wheel is an abrasive cutting tool. The grinding wheel has abrasive grains dispersed all over the wheel. Thousands of these solid, hard grains move against the workpiece to cut away tiny chips of material. Abrasive suppliers propose a wide range of products for a wide array of grinding applications in metalworking. Selecting the wrong product can cost the shop time and money.
 
 
Types of grinding wheels
 
 
Straight cup grinding wheel
 
They are the most common mode of a wheel that is originated on pedestal or bench grinders. They are widely used for centerless and cylindrical surface grinding operations. It forms a little concave surface on the piece when used on the periphery. It is used to gain on numerous tools like chisels. The size of the wheels varies to a great extent. Width and diameter of its face depend on the category of its work and machines grinding power. The Straight cup wheels form an option for cup wheels in cutter and tool grinders having an extra radial surface of grinding is favorable.
 
Tapered cup grinding wheel
 
The tapered Grinding wheel is a straight wheel that tapers externally towards the midpoint of the wheel. It is stronger than straight wheels, it accepts advanced lateral loads. Straight wheel with a tapered face is chiefly used for gear teeth and grinding thread etc.
 
Dish cup
 
This is used mainly in jig grinding and cutter grinding. It is a very thin cup-style grinding wheel which authorizes grinding in crevices and slot.
 
 
Features of Straight cup grinding wheel
 
High performance
Operational fluency

Specification of Tapered cup grinding wheel
 
It has an Elevated durability
It gives Perfect finish
A tapered grinding wheel is Impact resistance
Benefits of Tapered cup grinding wheel
Cool burn free cutting.
It provides excellent performance
It has a long life
It is a Versatile product
 
 
Conclusion
 
The grinding wheel is an abrasive cutting tool. It performs the same function as a tooth in a saw. Abrasive supplier offers a wide array of products for a wide grinding application in metalworking. Choosing the wrong product can cost shop time and money.
