What is Cylindrical Grinding: Un guide définitif

Cylindrical components are used in different industries. Cylindrical grinding is usually used to manufacture them or add a surface finish to them.

If you are looking forward to learning more about what is cylindrical grinding, the guide below offers everything in detail, so let's go through it.

What is Cylindrical Grinding?

The process of cylindrical grinding is used in industries where highly accurate and precise cylindrical components are required. The process uses cylindrical grinding machines with cylindrical grinding wheels.

These wheels are of abrasive nature and when they come in contact with the components, they end up removing material from the surface and help create the required shape.

Fundamental Principles of Cylindrical Grinding

The process of cylindrical grinding requires technicians to have an understanding of the basic principles that are associated with the machining process. These fundamental principles help in making informed decisions regarding production.

Cylindrical grinding is also a machining process in which most of the components are manufactured keeping precision and tight tolerance as a prime consideration.

Hence, understanding the selection of the right equipment, tools, and operating parameters is very crucial to getting the right components.

Advantages of Cylindrical Grinding

The process of cylindrical grinding has various benefits, and some of these are as follows:

• The process allows tight tolerance of the components, ensuring uniform results due to the high accuracy and precision offered.
• The grinding process is known for ensuring appropriate surface finishing, and hence, cylindrical grinding also ensures the properly finished surfaces of cylindrical components so that the need for polishing is eliminated.
• It is a versatile process that can cater to multiple materials and shapes.
• The process helps in relieving the internal stress of the components and hence improves their durability and strength.
• The cylindrical grinding process is suitable for all sizes of cylindrical components, which include large as well as small sized parts.

Disadvantages of Cylindrical Grinding

The process, along with benefits, also has some downsides, and these are as follows:

• The cost of a cylindrical grinding machine is high, and hence, a high initial investment is needed.
• The machine cannot be operated by everyone and needs skilled labor.
• There is a limitation on the shapes as only cylindrical components can be machined using this process.
• The process of cylindrical grinding is time-consuming compared to other types of machining processes.
• A lot of heat is generated during the process, which leads to tool wear.

Types of Cylindrical Grinding

The three types of cylindrical grinding processes are as follows:

External Cylindrical Grinding

External cylindrical grinding, as the name suggests, helps with grinding the outer part of the workpiece in cylindrical shapes.

The rotating grinding wheel removes the material from the component and creates the required finish. It is mostly opted for manufacturing pistons and shafts in the aerospace and automobile sectors.

Internal Cylindrical Grinding

Internal cylindrical grinding helps in machining the inner surface of the cylindrical component. The process uses internal grinders in which a rotating wheel is passed inside the component, which helps to attain a smooth finish and precise dimensions.

The process of internal grinding is very common in the medical industry and helps in grinding tubes.

Centerless Cylindrical Grinding

Centerless cylindrical grinding is the type of grinding in which no centers are required to support the component during the process.

The components are held using a regulating wheel and a grinding wheel. This offers excellent efficiency and high precision and is suitable for manufacturing bars and rods in cylindrical shapes that have uniform diameters.

Applications of Cylindrical Grinding

The process of cylindrical grinding is used in multiple applications, some of these are as follows:

Industrie automobile

The automobile industry requires several components that are cylindrical in shape to be machined with precision. Hence, cylindrical grinding is used in engine components, which include camshafts and crankshafts.

Industrie aérospatiale

Aerospace is a very critical industry and requires components that help in meeting the tight tolerance and strict dimensions. Aerospace components like turbine blades and other components of aircrafts are manufactured using a cylindrical grinding process.

Industrie médicale

Custom medical implants and prothèses can be manufactured using cylindrical grinding. Also, different surgical tools that are cylindrical in shape and need a smooth finish are subject to cylindrical grinding.

Alternatives to Cylindrical Grinding

Cylindrical grinding also has some alternatives that can be opted for instead of this process, and some of these are as follows:

Tournage

Tournage is a process in which a cutting tool helps in shaping the workpiece by removing material from it. The process of turning has the workpiece rotating while the tool cuts the material and helps it achieve a cylindrical shape.

It is a suitable process for components having uniform diameters, like pins and shafts, and it also helps with producing internal and external details on the cylindrical components like grooves, threads, and tapers.

Fraisage

Fraisage is a process in which the workpiece is stationary, and the cutting tool keeps on rotating. Milling works with cylindrical as well as non-cylindrical components and can even work with complex geometries.

The cutter moves in different directions to cut the material and allows the production of detailed components. It is mostly opted for manufacturing molds, gears, and components that have contours.
