The demand for Abrasive cutting and grinding discs are growing in the market with the time and this is mainly due to the vast advantages of Abrasive cutting and grinding discs.
A grinding disc is a disc composed of an abrasive compound and is used for abrasive cutting. In this disc, the abrasive plays the role of cutting as the teeth play in the cutting saws. A large number of hard, extreme grains move against the work-piece in order to remove little chips of material.
The abrasive grains used in it:
- Aluminum oxide (A)
- Silicon carbide (S)
- Ceramic (C)
- Diamond (D, MD, SD)
- Cubic boron nitride (CBN)
Types of grinding discs used :
- Straight grinding wheels
- Cylinder or wheel rings
- Tapered grinding wheels
- Straight cup
- Dish cup
- Saucer grinding wheels
- Diamond grinding wheels
Applications of the grinding discs :
- Slitting and parting of the material
- Descaling
- Deburring
- Stock removal finishing of the cylindrical and flat surfaces.
- Surface finishing
- Grinding of the tools
Advantages of the abrasive cutting and grinding discs:
1) Ability to withstand impact load: The bond in the grinding disc is known as Resin bond. The conventional abrasive resin bonded wheels are widely used for the heavy-duty grinding because of their ability to withstand impact load. This bond is also known for its vibration absorbing behavior.
2) Good surface finishing: The grinding discs provide good surface finishing and they are also well known for their ability to provide better surface finishing than the other tools. Even they reduce the masses of the material from the surface according to the need. Due to such quality service that can be provided with the help of grinding discs, they are in high demand in the market nowadays.
3) Provides chip clearance: The characteristic known as "Pores", which is available due to the arrangement of the abrasive grains and the bond present in the grinding wheel. These pores are actually designed on the basis of application needs and for providing chip clearance. This characteristic helps in cutting the material smoothly.
4) High dimensional accuracy: By using the abrasive grains in these discs, it provides high dimensional accuracy up to 0.025 µm. Due to such factors of abrasive cutting discs, they are also known as precision cutting tools. So, where ever high precision or dimensional accuracy is needed, Abrasive cutting and grinding tools can be used.
5) Applicable to a vast variety of materials: It is applicable for machining both the hardened and unhardened materials, which makes it a versatile tool for cutting and grinding purposes. Its structure helps it to achieve such strength to grind hardened materials and also work on delicate things.
6) Efficient and Cost-effective: Its initial cost is a bit high, but the service it provides, makes the total production cost low at the end. By seeing this, we can conclude that it is a very effective tool for cutting and grinding.
The vast usage and high demand for abrasive cutting and grinding disc are due to its advantages and benefits.
