Cylindrical grinding is a common process used to finish workpieces. But how many centers hold the workpiece during cylindrical grinding?

Checkout this video:


Cylindrical grinding is a machining process that holds the workpiece in a rotating chuck and supports it with a center to rotate it around an axis. The grinding wheel then removes any material that remains on the surface of the workpiece.

What is Cylindrical Grinding?

Cylindrical grinding is a process used to shape workpieces like cylindrical gears and workpieces with diameters greater than 100mm. Grinding allows for tight tolerances, a smooth surface finish, and the ability to shape the outside of the workpiece. The process can be performed on many different materials including metals, plastics, and composites.

How Many Centers Hold the Workpiece?

There are two types of grinding machines conventionally used in metalworking shops for grinding cylindrical surfaces–“plain” or “universal” cylindrical grinders and specialized centerless grinders. Plain cylindrical grinders have a wheelhead with one wheel installed and anotherWheel mounted on a separate slides. The workpiece is supported between centers, or on a chuck, and rotated during grinding. The wheelhead can be swiveled from 0° to 90° to accommodate various workpiece shapes, such as conical or angular surfaces. Centerless grinders save time by not having to load, unload, and reposition the workpiece for successive operations, as each new surface is generated during the grinding process. In certain cases, however, it may be necessary to hold the workpiece on more than one center when extensive machining of the periphery is required–this necessitates using multiple slides simultaneously.

Advantages of Cylindrical Grinding

Cylindrical grinding is a handy process for creating smooth, consistent surfaces on workpieces of all shapes and sizes. Whether the workpiece is cylindrical in shape or not, grinding can provide the necessary dimensional accuracy and surface finish you’re looking for.

One of the main advantages of cylindrical grinding is that it can be easily automated. Automating the process allows for increased efficiency and consistency, as well as reduced operator fatigue. Cylindrical grinding can also be used to create uniform surfaces on workpieces with irregular shapes.

Disadvantages of Cylindrical Grinding

There are several disadvantages of cylindrical grinding. First, it is not able to produce as fine of a finish as other grinding methods. Second, it can only be used on very small parts. Third, the setup time is very long and it is not able to be used on complex shapes. Finally, the cost of cylindrical grinding is very high.


Based on the information above, it appears that the majority of workpieces in cylindrical grinding are either held between centers or by a chuck.There are advantages and disadvantages to each method, and it is important to consider them before deciding which is best for your particular application.If you have any questions or would like more information, please contact us.
